An external transformer may be required with certain input/output voltage configurations. Consult factory for details.
Input voltage on 17.5KVA model limited to 277 and 347VAC only.
102. Receiving, Moving and Storing Systems and Batteries
102.1 Shipping Damage
LSN inverter systems and batteries are normally shipped separately.
Carefully inspect all cartons upon receipt for evidence of shipping damage.
Notify carrier immediately of leaking or damaged cartons for possible concealed damage.
All LSN electronics cabinet cartons are shipped with tip and vibration indicators.
Refuse all shipments in which the tip or vibration indicators have been activated.
102.2 Moving Units and Batteries
CAUTION: Batteries and LSN Electronics cabinets are very heavy. Proper equipment should
always be used to move batteries and units to avoid damage and personal injury.
WARNINGS:
• ALWAYS WEAR PERSONAL EYE PROTECTION WHEN WORKING WITH BATTERIES - SEE PAGE 10
• Batteries contain liquid caustic or acid electrolytes which CAN CAUSE SEVERE BURNS.
Care must be taken when moving batteries to avoid tipping and spillage of electrolyte material.
In case of accidental spill.
ANTIDOTE:
• EYES: Flush immediately with flowing water for at least 15 minutes. Seek medical attention.
• EXTERNAL: Flush immediately with water. Seek medical attention.
102.3 Temporary Storage of Units and Batteries
For temporary storage of LSN inverter systems and batteries prior to installation, select a clean, cool, dry location with
normal ventilation for human habitation and level floors.
CAUTION: Batteries and LSN Electronics cabinets are very heavy. Check to assure that the floor in the
temporary storage area is capable of safely bearing the load.
IMPORTANT:
Lengthy storage of batteries will cause irreversible damage to the cells.
Failure to connect LSN inverter system batteries to an energized charging circuit within 90 days from the date
of shipment will void the battery warranty.
Storage Temperature:
Store all batteries at 0° to +40° C (32° to +104° F). Batteries will have a longer shelf life if stored at 25° C (77° F).
The LSN electronics and battery cabinets may be stored at -20° to +60° C (-4° to +140° F).
Ventilation: The air around the unit must be clean, dust-free, and free of corrosive chemicals or other contaminants. Do not place
the LSN inverter system or batteries in a sealed room or container.
DANGER: EXPLOSIVE - CAN CAUSE BLINDNESS OR OTHER SEVERE INJURIES.
Every type of battery can produce hydrogen gas, even sealed, maintenance-free batteries. The gas is vented through
the vent caps and into the air.
Do not allow smoking, sparks, or flames in battery storage location because hydrogen is concentrated under
the vent cap of each cell of the battery. Hydrogen is highly explosive, and is hard to detect because it is
colorless, odorless, and lighter than air.

103. Installation Requirements
103.1
Operating Environment
Install the LSN inverter system in a clean, cool, dry place with normal ventilation for human habitation and level floors.
CAUTION: Batteries and LSN Electronics cabinets are very heavy. Check to assure that the
floor is capable of safely bearing the load.
Operating Temperature: LSN inverter Systems are UL Listed for 20° to 30° C (+ 68° to +86° F) operation.
The LSN Inverter System has a designed operating range of 0° to +40° C (+32° to +104° F) at up to 95% relative
humidity. Installation in environments at the temperature extremes of the designed operating range may effect unit
performance or reduce service life.
Battery performance and service life is maximized if the operating temperature is maintained at 25° C (77° F) .
Ventilation: The air around the unit must be clean, dust-free, and free of corrosive chemicals or other contaminants. Do not place
the LSN inverter system or batteries in a sealed room or container.
Batteries:
The temperature should be near 25° C (77° F) for optimum battery performance.
Temperature Effect On Performance:
Batteries will be less efficient at temperatures below 18° C (65° F), and high temperatures will reduce battery life.
Typically, at 35° C (95° F), battery life will be half of what it would be at normal temperature of 25° C (77° F). At 45° C
(113° F), battery life will be one-fourth of normal.
WARNING: Every type of battery can produce hydrogen gas, even sealed, maintenance-free batteries. The gas is
vented through the vent caps and into the air, mainly when the unit is charging the batteries. The batteries produce the
most hydrogen when maximum voltage is present in fully charged batteries. The amount of current that the charger
supplies to the batteries (not the battery ampere-hour) determines how much hydrogen is produced.
Do not allow smoking, sparks, or flames in battery storage location because hydrogen is concentrated under
the vent cap of each cell of the battery. Hydrogen is highly explosive, and is hard to detect because it is
colorless, odorless, and lighter than air.
!
CAUTION
NEVER INSTALL BATTERIES IN A
SEALED ROOM OR ENCLOSURE
IMPORTANT:
Lengthy storage of batteries will cause irreversible damage to the cells.
Failure to connect LSN inverter system batteries to an energized charging circuit within 90
days from the date of shipment will void the battery warranty.
103.2
High Altitude Operation:
The maximum operating temperature drops 1° Celsius per 300 meters (2° F per 1000 feet) above sea level. Maximum
elevation is 3000 meters (10,000 feet).

105. Battery Installation and Connection
Installing the Batteries and DC Wiring
Important Safety Precautions
The installer must take these precautions:
1. Wear protective clothing, eye-wear, rubber gloves and boots. Batteries contain corrosive acids or
caustic alkalis and toxic materials and can rupture or leak if mistreated. Remove rings and metal
wristwatches or other metal objects and jewelry. Don’t carry metal objects in pockets where the
objects can fall onto the batteries or into the LSN inverter system or battery cabinet.
2. Tools must have insulated handles so that they will not short battery terminals. Do not allow a tool to
short a battery terminal to another battery terminal or to the cabinet at any time. Do not lay tools or
metal parts on top of the batteries, and do not lay any objects where they could fall onto the batteries
or into the cabinet.
3. Install the batteries as shown on the battery wiring diagram provided in this manual or with the
battery cable kit. When connecting cables, never allow a cable to short across a battery’s terminals,
the string of batteries, or to the cabinet.
4. Align the cables on the battery terminals so that the cable lug will not contact any part of the cabinet
even if the battery is moved. Keep the cable away from any sharp metal edges.
5. Install the battery cables so they cannot be pinched by the battery cabinet or the LSN inverter system
doors.
6. External battery cabinet chassis ground (or earth) must be connected to the LSN inverter system
unit’s chassis ground (or earth). The ground conductor must be insulated. If you use conduit, this
ground conductor must be routed in the same conduit as the battery conductors.
7. Where conductors may be exposed to physical damage, protect conductors in accordance with NEC
requirements.
8. Full voltage and current are always present at the battery terminals. The batteries used in this
system can produce dangerous voltages, extremely high currents, and possible risk of electric
shock. Batteries may cause severe injury if the terminals are shorted together or to ground (earth).
Be extremely careful to avoid electric shock and burns caused by contacting battery terminals or
shorting terminals during battery installation. Do not touch uninsulated battery terminals.
9. A qualified electrician who is familiar with battery systems and required precautions must install and
service the batteries. Any battery used with this unit shall comply with the applicable requirements
for batteries in the standard for emergency lighting and power equipment, UL 924. Cabinets are
designed to be used with, and batteries must be replaced by identical cells or a Dual-Lite approved
equivalent. If using substitute batteries not supplied by Dual-Lite, the unit’s UL listing will be void,
and the equipment may fail to perform properly. The installation must conform to national and local
codes as well. Keep unauthorized personnel away from batteries.
10
105.1
Tools
The following tools are required to install the system batteries. Other tools may be necessary if optional batteries have
been ordered.
CAUTION: Always use insulated tools for battery installation. Always torque to the manufacturer’s recommendations.
• Petroleum Jelly
• Slotted Screwdriver • 3-inch Socket Extension • Ratchet
• Electrical Tape
• Digital Volt-Ohm Meter
105.2

Installation Considerations
This section explains how to install the LSN system’s batteries, fuses, and cables. A qualified electrician who is
familiar with battery installations and applicable building and electrical codes should install the batteries.
1. Location
The system batteries install in separate battery cabinet(s). Before installing the batteries, install the LSN inverter
system and any battery cabinets in their permanent location. See Section 103 to choose a location and Section
104 for instructions on securing the LSN inverter system and battery cabinets to the wall.
CAUTION: Do not move the LSN inverter system or separate battery cabinet(s) after installing the batteries. The
unit, cabinet and/or batteries may be damaged.
2. Inter-Cabinet Connections
Wherever conductors may be exposed to physical damage, the conductors must be protected in accordance with
NEC requirements. This includes battery cables between the LSN inverter system and battery cabinet(s) and
cables between battery cabinets.
Dual-Lite recommends routing the battery cables through the chase nipples supplied with the unit. The battery
cables shipped with the unit are designed for an installation with the battery cabinet(s) installed in the standard
configurations shown in Section 104.1
IMPORTANT: If cabinets are installed in configurations other than those shown in

106. AC Connections
CAUTION
A. All LSN inverter system units contain hazardous AC and DC voltages. Because of these voltages, a qualified
electrician must install the LSN inverter system, AC line service, and batteries. The electrician must install the AC
line service according to local, state and NEC codes and must be familiar with batteries and battery installation.
B. Before installing, maintaining, or servicing the unit, always remove or shut off all sources of AC and DC power and
shut off the LSN inverter system. Disconnect AC line input at the service panel and turn off the Main DC Switch,
the Main AC Switch, and the Master Switch to make sure the unit will not supply output voltage.
C. Whenever AC and/or DC voltage is applied, there will be AC voltage inside the LSN inverter system unit; the
unit can supply power from AC line or from its batteries. To avoid equipment damage or personal injury, always
assume that there may be voltage inside the LSN inverter system.
D. Remove rings, watches, and other jewelry before installing the AC wiring. Always wear protective clothing and eye
protection and use insulated tools when working near batteries. Whenever servicing an energized unit with the
inside panel open, electric shock is possible; follow all local safety codes. TEST BEFORE TOUCHING!
E. Before installing an external bypass switch, make sure that both the bypass switch and the AC disconnect switch
are off.
F. To reduce the risk of fire or electric shock, install the LSN inverter system and the batteries in a temperaturecontrolled and humidity-controlled indoor area free of conductive contaminants. See Section 103 for operating
environment specifications.
Preparations
1. Open the circuit breaker access door. Make sure all breakers are in the off position.
2. Make sure the LSN inverter system input and output voltages are correct for the particular application. Remember
that the LSN system provides single-phase power only.
3. The input circuit breaker in the input service panel provides the means for disconnecting AC to the LSN inverter
system. If using a bypass switch, the bypass enclosure also includes a separate AC Disconnect switch. Only
authorized persons shall be able to disconnect AC to the unit. (See NEC 700-20 and 700-21.) Bypass switches
with AC Disconnect have handles that can accept a lock to restrict control to authorized persons. If using the input
circuit breaker to disconnect AC, make sure that only authorized persons have control of the circuit breaker panel
to meet the requirements of NEC 700-20.
4. If installing a bypass switch, use the installation and wiring instructions supplied with the bypass switch.
NOTE: Systems not using a bypass switch may have optional output circuit breakers and/or a normally off relay.
18
CAUTION
To prevent electrical shock or equipment damage, for all units, with and without a bypass switch, make sure the
Master Switch, the Main AC Switch, the Main DC Switch on the inverter and the bypass switch (if applicable), all
output circuit breakers, and the AC input at the service panel are all off before making AC connections to the LSN
inverter system.
5. If not previously done, remove knockouts for AC Input and AC Output in the top of the LSN inverter system (See
Figure 1 in Section 104.1).
CAUTION: Do not drill the cabinet; drill filings may damage the unit and prevent it from operating. If larger
knockouts are needed, use a chassis punch to enlarge the appropriate knockout. Do not add additional or
unnecessary knockouts.
If planning to connect a computer or terminal to the LSN inverter system unit’s RS232 port, remove one of the
knockouts in the top of the unit at this time (See Figure 1 in Section 104.1). If necessary, enlarge the knockout; it
should be able to accept at least 1.25-inch (32 mm) conduit.
6. Install the input and output conduit.
7. IMPORTANT: Run the AC Input service conductors and AC Output conductors through separate conduits.
Emergency output conductors and non-emergency output conductors must also be run through separate conduits.
LSN inverter system emergency output circuits shall be installed in dedicated conduit systems and not shared with
other electrical circuits as described in NEC 700-9(b).
106.2 AC Input and AC Output Connections
Make all AC input and output connections to the LSN inverter system as indicated on labels within the cabinet. If
system was supplied with internal output circuit breaker distribution option, remove circuit breaker distribution cover
and make wiring connections directly to the circuit breakers and re-install cover.
If the LSN system is to incorporate a bypass switch, it is recommended that the "Phase Check Procedure" as
described in Section 109 be performed - wiring instructions are supplied with the bypass switch.
IMPORTANT: To make sure phasing is correct, make all terminal strip connections exactly as they are labeled. Good
ground connections are necessary to reduce electrical noise and ensure safe operation of the LSN inverter system
unit and the loads.
Caution: Torque all connections in accordance with the following tables.
Failure to do so may create an unsafe condition or fire hazard.

109. Maintenance Bypass Switch Phase Check
If you are not using a bypass switch with the LSN inverter system, the phase check is not necessary, so you can
skip this section and go directly to Section 110 to complete the system start-up. If the LSN unit does have a bypass
switch, complete the following phase check once you have made all of the terminal strip connections and installed the
batteries.
!
CAUTION: Before you switch the bypass switch from “UPS” to “AC Line,” make sure you follow the steps below to check for correct operation.
1. Make sure the main circuit breaker at the load service panel is off, or make sure the connected loads (protected
equipment) cannot receive power from the LSN inverter system. Turn the bypass switch to the “OFF” position. At the AC service panel, apply power to the LSN system and the bypass switch. Turn the LSN Master ON/OFF
Switch to the "ON" position. Turn the bypass switch to the "ON" position.
2. Press the precharge switch for ten seconds. Release the precharge switch and immediately turn the LSN Main
DC Switch to the "ON" position.
3. Turn the Main AC Switch inside the LSN system to the "ON" position. The loads (protected equipment) should still
be off at this time. After a short startup, the READY LED and AC-ON LED will illuminate. The LSN inverter system
is ready to supply output power.
4. Make sure the voltage from the LSN system to the connected loads is close to the voltage from AC line to the
bypass switch. (There may be slight differences.) To measure this, use an AC voltmeter check the voltage
between the following points on the bypass switch terminal strip. (See the terminal strip label). Record the
voltages below.
AC from LSN Output
AC Line Input
(60 Hz 208 or 240VAC only) 7 to 8_________VAC
11 to 12_________VAC
(60 Hz 208 or 240VAC only) 6 to 8_________VAC
10 to 12_________VAC
(All other voltages)
7 to 8_________VAC
11 to 12 _________VAC
The voltages recorded in the first column should be similar to the voltages in the second column. The voltages may
vary slightly. If the voltage readings vary more than a few volts, shut down AC line and the LSN system. Check
all connections at the terminal strip, and correct any wiring problems. If help is required, contact Dual-Lite’s
Technical Support Center at 1-800-848-6439.
Important: If the AC Input voltage is 208 volts, you will normally measure 88VAC between output terminals 6 and 8. Never connect any 120-volt load to the 88-volt terminals.
5. If a Break-Before-Make type bypass switch is being used, proceed to step 8.
If a Make-Before-Break bypass switch is being used, make sure the AC voltages from the LSN system output and
the AC line input are in phase. To do this, measure the AC voltage between the following points on the bypass
switch terminal strip. These measurements should not be more than 100VAC; if measurements exceed 100VAC,
contact Dual-Lite’s Technical Support Center at 1-800-848-6439.
(60 Hz 208 or 240 V only) 8 to 12_________VAC
(All other voltages) 7 to 11_________VAC
6. Measure the AC voltage between the following points on the bypass switch terminal strip. This reading should not
exceed 1VAC; if measurements exceed 1VAC, contact Dual-Lite’s Technical Support Center at 1-800-848-6439.
(60 Hz 208 V or 240 V)
(60 Hz 120 V or 50 Hz 220/230/240 VAC)
6 to 10_________VAC
8 to 12_________VAC
21
CAUTION: If a Make Before-Break type bypass switch is being used, equipment will be damaged if the switch position is changed while AC line voltage is applied and the LSN system is turned off
or operating in inverter (DC) mode. Make sure the LSN system is running on line (AC mode) and supplying
output voltage before changing the bypass switch position. See the instructions supplied with your bypass
switch.
7. Turn the bypass switch to the “LINE" position. Using an AC voltmeter, verify the voltage to your protected
equipment load is correct. Voltage can be verified at the Load Distribution Panel.
8. Turn the bypass switch to the “UPS” position and measure the voltage to your protected equipment load once
more (at the Load Distribution Panel). Verify the voltage is correct.
9. If all readings during the voltage and phase check are acceptable, reattach the bypass switch cover. Tighten the
retaining screws securely. Proceed to Section 110 to complete the system start-up.

the front panel "AC-ON" and "READY" LEDs should illuminate, and the system LCD display will begin to
scroll the system parameters.
11. Depending on the state of charge of the batteries, the front panel Charging LED may illuminate.
111. System Verification
At this point, the connected load should be energized, the "Ready" and "AC On" LEDs should be lit, and the display
is scrolling through 18 operating messages. Wait 2 minutes while the system completes its final set up, and then look
at the various messages and make sure they are within expected limits. If any alarms sound, go to section 205 for
further instructions. If you need assistance, call Dual-Lite's Technical Support Center at 800-848-6439.
If no alarms sound, perform the following inverter test to verify its operation:
Once the “Ready” LED is illuminated, simulate a power failure by opening the AC input circuit breaker. The inverter
and the cooling fans will begin operating. All connected loads should be energized and operational, HID fixtures
should not “wink-out”.
Allow the inverter to run for several minutes or until satisfied with its operation. Close the AC input breaker to end the
test and return the unit to standby mode.
Note: It will take a few seconds for the unit to re-synchronize with the input line. The inverter will turn off when
synchronization is achieved.

202. System Self-Diagnostics
Self-testing/self-diagnostic electronics perform continuous testing of subsystems, insuring performance to prescribed
operating parameters. Operation outside of prescribed limits or system malfunctions will result in an alarm indication
on the system’s user interface display panel. Depending on the type of alert, the panel alarm indication may be visual
or audiovisual.
User-programmable discharge tests are automatically performed on a monthly and annual basis. Date, time and
duration of these tests can be programmed to meet state, local authority and individual requirements. All testing events are automatically logged in memory and can be displayed on the user interface panel.
203. System Auto Testing
The LSN inverter system automatically performs three sophisticated, microprocessor-controlled system discharge
tests; a weekly test, a monthly test and an annual test. The following parameters affect these tests:
Weekly test

Annual Test
• Schedule (264) • Time of day for monthly test (73) • Time of day for annual test (185)
• Date for monthly test (127)
• Date for annual test (184)
• Monthly test duration (129)
• Annual test duration (129)
• Monthly reschedule interval (183)
• Annual reschedule interval (186) 203.1

Extended Power Outages
Every week (at a time and date specified in parameter 264) the system will automatically operate the inverter for one
minute. During this test, the system will monitor inverter output and connected load. The unit automatically records
the results of the test in parameter 26, which can be displayed from the user interface panel.
Every month (or at the interval specified in parameter 183) the LSN Inverter System automatically performs a
discharge test to check battery capacity and emergency inverter operation. The duration of the monthly test cycle is
controlled by parameter 129, set at the factory for 5 minutes. The unit automatically records the results of the test in
parameter 26, which can be displayed from the user interface panel.
Once a year, the unit automatically performs a battery exercise cycle/discharge test by running the unit in emergency
mode for 90 minutes. It is recommended that it be scheduled at a time when the area protected by the LSN system
will be unoccupied for a full 48 hours to allow the batteries time to recover to full capacity. The date on which the
annual test takes place is stored in parameter 184 .
During extended power outages, the LSN inverter system will provide power to all connected loads for its full rated
discharge time.
NOTE: During emergency operation of the LSN system, parameter 9 allows the user to determine how many minutes
of runtime remain in the normal discharge period. At a set number of minutes prior to the end of the runtime (factory
default setting is 30 minutes), the unit will sound a “Low Runtime” alarm. The unit may also simultaneously sound a
“Near Low Battery” alarm. When either of these alarms occur, an orderly shutdown of any non-emergency equipment
that may be connected to the system should be conducted in order to allow the inverter to operate critical emergency
equipment for a longer period of time. Following the normal discharge period, the unit will continue to operate normally until battery capacity reaches a preset disconnect limit. At this point, the inverter will automatically disconnect inverter AC output power to the load. The
unit’s electronic controls will remain powered by the system batteries until the batteries reach a second pre-set low
imit at which point the unit will shut down completely to prevent deep discharge damage to the unit batteries.

205. Alarms
What They Mean And How To Respond
When the LSN system detects a problem, it:
• Sounds an alarm
• Illuminates the red "ALARM" LED on the User Interface Panel, and
• Displays an error message
If the system was ordered with an optional e-mail device and the alarm condition lasts for more than five minutes, the
unit will automatically send an alarm e-mail to all programmed e-mail locations.
In The Event Of An Alarm Condition
1. Read the user interface panel display to determine the specific alarm condition.
2. Temporarily silence the alarm by pressing [MAN],3,2 on the user interface panel. The display should read "Alm
Silenced". This procedure silences the indicated alarm only. Should another failure be detected, the alarm for
that condition will sound.
3. Find the message or code in the following table. The table provides alarm information and appropriate response
procedures.
For illustration purposes, the model used is a 120-volt in, 240-volt out, 15 KVA unit operating with a nominal battery
bank of 144 volts DC. The first number in the alarm messages is the actual measured value, the second is the preset
limit. This table is offered as a guide only, other factors may cause the various alarms to activate.
NOTE - Whenever contacting the Dual Lite Technical Support Center, it is desirable to use a telephone as close to
the system as possible in order to help our technicians determine the cause of the alarm condition.

300. Maintenance
300.1
Safe Shut Down Procedure
CAUTION
To avoid possible equipment damage or personal injury, assume that there is AC voltage present inside the LSN
inverter system unit any time AC input power or DC battery voltage is applied. The inverter is capable of providing
output voltage from the batteries even when there is no AC input line voltage. When AC input voltage is present, the
unit can provide output voltage even when the batteries are disconnected.
AC AND DC VOLTAGES WILL BE PRESENT INSIDE THE UNIT UNTIL LINE AC IS
DISCONNECTED AND ALL INTERNAL SWITCHES ARE TURNED OFF.
Do not touch components inside the unit. DC voltage is always present at the batteries and battery cables.
If an external bypass switch is not used, turn off all connected equipment (loads) at their source and proceed
to “Final Shut Down Procedure” below.
A. Bypass Switch Disconnect
If the unit utilizes a bypass switch, check the label to determine whether it is Break-Before-Make or Make-BeforeBreak.
Follow the instructions for the type of switch identified:
Break-Before-Make: If a Break-Before-Make (BBM) external bypass switch is used, the switch will temporarily
break input power as it switches from emergency inverter power to utility power (LINE) or back to CIS power. 1. Shut down all connected equipment (loads)
2. Turn the bypass switch to the LINE position.
3. If necessary, restart connected equipment.
Make-Before-Break: If a Make-Before-Break (MBB) bypass switch is used.
1. Make sure the AC Line light is on
2. Make sure the “Emergency Power” light on the user interface panel is off.
3. The LSN system must be providing utility AC pass-through to the connected equipment.
CAUTION:
If a Make-Before-Break bypass switch is used, equipment will be damaged if the switch position is changed when
line is applied and the LSN system is operating in the “Off” or “On” (Emergency Battery Operation) Mode. See the
instructions packed with the bypass switch.
4. Turn the bypass switch to the LINE position.
B. Final Shut Down Procedure
1. Open the unit’s front door.
2. Turn off the Master Switch, the Main DC Switch, the Main AC Switch and any Output Circuit Breakers.
CAUTION: HAZARDOUS ENERGY IS STORED IN CAPACITORS INSIDE THE LSN UNIT. AFTER TURNING OFF
SWITCHES, ALLOW 5 MINUTES FOR CAPACITORS TO DISCHARGE BEFORE ATTEMPTING ANY SERVICE
PROCEDURES.
3. If the service technician does not need to access the inside of the unit, close and lock the unit’s front door.
4. If the unit will be shut off for an extended period of time, recharge the batteries every 60 to 90 days.
CAUTION: The batteries will be damaged and the warranty voided if not routinely recharged.
NOTE: To turn power back on, follow the “System Startup Procedure” outlined in Section 110. Be sure to
complete all of the steps to assure the unit will operate properly.
35
300.2
Routine System Maintenance
The LSN inverter system unit is designed to provide years of trouble-free operation. Its self-testing/self-diagnostic
microprocessor will check the batteries and inverter regularly to ensure proper operation.
The unit does require some routine attention to assure peak performance. Dual-Lite recommends a Preventative
Maintenance check be performed by a qualified service technician at least every six months. The technician must
observe important safety precautions while performing the following recommended tasks: •
•
•
•
•
•
•
Inspect and clean the unit interiors;
Inspect and record any Alarm and Inverter Logs;
Inspect all batteries for leaks, case swelling or terminal corrosion;
Check the AC and DC meter functions and recalibrate if necessary;
Perform an emergency operation test to check operation of all critical connected loads;
Check the values of metered parameters and system logs,
Change air filters (see below).
NOTE: If the LSN unit is installed in an area where audible alarm signals may not be
heard, a weekly visual check is advised.
300.3
Changing Air Filters
CAUTION
This procedure must be done by a qualified service person ONLY! Based on the installation environment, LSN inverter system air filters should be changed at least every six months to
assure sufficient airflow to prevent overheating of unit electronics.
To change unit air filters, follow these steps:
1. Follow the steps in Section 207.1 to safely shut down the unit. Remember to leave the system door closed for at
least five minutes to allow capacitors to discharge. 2. After five minute period, open the system door.
2. Remove old filters which are held in place by double-sided adhesive tape.
3. Clean off any tape adhesive residue from back of door.
4. Replace filters using Dual-Lite Filter Kit
5. Close the system door.
6. Follow the “System Startup Procedure” outlined in Section 109. Be sure to complete all of the steps to assure the
unit will operate properly.
36
300.4
Battery Maintenance and Replacement
This section provides precautions for qualified service personnel working with unit batteries. No user serviceable
parts are within the system's cabinets
Important Safety Precautions
The service technician must take these precautions:
1. Wear protective clothing, eye-wear, rubber gloves and boots. Batteries contain corrosive acids or
caustic alkalis and toxic materials and can rupture or leak if mistreated. Remove rings and metal
wristwatches or other metal objects and jewelry. Don’t carry metal objects in pockets where the
objects can fall onto the batteries or into the LSN inverter system or battery cabinet.
2. Tools must have insulated handles so that they will not short battery terminals. Do not allow a tool to
short a battery terminal to another battery terminal or to the cabinet at any time. Do not lay tools or
metal parts on top of the batteries, and do not lay any objects where they could fall onto the batteries
or into the cabinet.
3. Install the batteries as shown on the battery wiring diagram provided in this manual or with the
battery cable kit. When connecting cables, never allow a cable to short across a battery’s terminals,
the string of batteries, or to the cabinet.
4. Align the cables on the battery terminals so that the cable lug will not contact any part of the cabinet
even if the battery is moved. Keep the cable away from any sharp metal edges.
5. Install the battery cables so they cannot be pinched by the battery cabinet or the LSN inverter
system doors.
6. External battery cabinet chassis ground (or earth) must be connected to the LSN inverter system
unit’s chassis ground (or earth). The ground conductor must be insulated. If you use conduit, this
ground conductor must be routed in the same conduit as the battery conductors.
7. Where conductors may be exposed to physical damage, protect conductors in accordance with NEC
requirements.
8. If replacing batteries or repairing battery connections, follow the procedure in this manual to shut
down the LSN inverter system and remove both AC and DC input power.
9. Full voltage and current are always present at the battery terminals. The batteries used in this
system can produce dangerous voltages, extremely high currents, and possible risk of electric
shock. Batteries may cause severe injury if the terminals are shorted together or to ground (earth).
Be extremely careful to avoid electric shock and burns caused by contacting battery terminals or
shorting terminals during battery installation. Do not touch uninsulated battery terminals.
10. A qualified electrician who is familiar with battery systems and required precautions must install and
service the batteries. Any battery used with this unit shall comply with the applicable requirements
for batteries in the standard for emergency lighting and power equipment, UL 924. Cabinets are
designed to be used with, and batteries must be replaced by identical cells or a Dual-Lite approved
equivalent. If using substitute batteries not supplied by Dual-Lite, the unit’s UL listing will be void,
and the equipment may fail to perform properly. The installation must conform to national and local
codes as well. Keep unauthorized personnel away from batteries.
37
CAUTION:
A battery can present a risk of electrical shock and high short circuit current. Battery replacement should only
be performed by qualified service personnel familiar with battery systems. All safety precautions outlined at the
beginning of this section must be observed when servicing, maintaining or replacing batteries
Routine Battery Inspection and Maintenance
Sealed Lead-Calcium Batteries (Includes Type S and Type G batteries)
Lead-Calcium cells are the most common type of battery used today in standby equipment. By design it is as
maintenance free as a battery can be. Coupled with the diagnostic and self-testing capabilities of the LSN system,
these batteries provide one of the most reliable and carefree inverter systems available today. It is recommended,
however, that some simple steps be taken to increase system life and maximize reliability:
•
If system is installed in a remote area where the system's alarms may not be heard, it is recommended that the
system be checked weekly for alarm conditions,
•
A quarterly visual check of the batteries should be conducted to look for deformities in the cases and terminal
corrosion. Any defective batteries should be replaced. All corroded terminals, regardless how slight, are to be
cleaned and retightened at once to prevent failure of the entire battery bank.
•
Once a year, all battery connections should be checked for tightness and re-torqued if necessary. Torque
specifications can be found on the battery label.
Nickel-Cadmium Batteries
Used in harsher environments, the wet nickel cadmium battery is designed for a 25-year life. When properly
maintained it will give years of reliable performance. Care must to be taken to maintain adequate electrolyte levels
and terminal cleanliness. Use only distilled water when necessary. Never use any kind of acid to refill the battery,
serious damage and injury may occur.
The same frequency and procedures as listed above for the lead-calcium batteries should be followed.
If you have any questions, contact Dual Lite's Technical Support Center at 1-800-848-6439.
Please dispose of all batteries properly.
Battery Replacement Procedure
WARNING: Always use the same quantity and type of battery as replacements.
Substituting batteries not supplied by Dual-Lite will void the UL listing of the system and may cause equipment failure.
To ensure the superior performance of your LSN inverter system and to maintain proper charger operation, replace
spent batteries only with Dual-Lite cells having the same part number, voltage and ampere-hour rating as the original
batteries.
1. Follow the proper shut down procedure as described in Section 300.1.
2. Remove battery cabinet fuses and test them for continuity. Faulty fuses will prevent batteries from charging and
render the battery bank useless during a power outage.
3. Break down the battery bank beginning with the intercell connectors. These cables tie the batteries installed on
the same shelf together.
4. Next remove the inter-tier cables. These cables connect the batteries located on different shelves together.
38
5. Remove the batteries from the cabinet. Batteries can be very heavy, use proper lifting methods when removing
battery.
6. Install new batteries following the instructions outlined in Section 105.3.
Battery Disposal
WARNINGS:
Do not dispose of batteries in a fire, the batteries could explode.
Do not open or mutilate batteries.
Released electrolyte is highly toxic and harmful to the skin and eyes.
CAUTION:
Batteries contain lead. Many state and local governments have regulations about used battery disposal. Please
dispose of the batteries properly. For help, contact the Dual-Lite Technical Support Center.
301. Warranty Information
