General Information

1.1 INTRODUCTION

This manual has been prepared especially for the purpose of familiarizing personnel with the design, application, installation, operation and servicing of the applicable equipment. Read the manual carefully and comply with all instructions. This will help to prevent accidents or damage to equipment that might otherwise be caused by carelessness, incorrect application, or improper procedures.

Every effort has been expended to make sure that the contents of this manual are both accurate and current. The manufacturer, however, reserves the right to change, alter or otherwise improve the product at any time without prior notice.

1.2 UNpACkING

Carefully unpack the transfer switch. Inspect closely for any damage that might have occurred during shipment. The purchaser must file with the carrier any claims for loss or damage incurred while in transit.

Check that all packing material is completely removed from the switch prior to installation.

1.3 EqUIpmENT DESCRIpTION

The automatic transfer switch is used for transferring electrical load from a UTILITy (NORMAL) power source to an GENERATOR

(STANDBy) power source. Such a transfer of electrical loads occurs automatically when the UTILITy power source has failed or is substantially reduced and the GENERATOR source voltage and frequency have reached an acceptable level. The transfer switch prevents electrical feedback between two different power sources

(such as the UTILITy and GENERATOR sources) and, for that reason, codes require it in all standby electric system installations.

The transfer switch consists of a transfer mechanism, UTILITy

SERVICE DISCONNECT circuit breaker, a relay control, fuses, terminal strip, and fuse holder for connection of sensing wires.

This transfer switch is suitable for use as service equipment.

1.3.1 transfer switch mechanism

These switches (Figure 1.1) are used with a single-phase system, when the single-phase NEUTRAL line is to be connected to a

Neutral Lug and is not to be switched.

Solderless, screw-type terminal lugs are standard.

• The conductor tightening torque is 375 in-lbs. (Line), 275 inlbs. (Load - ATS)

1.3.3 Load shed modULe (Lsm)

The Load Shed module is designed to prevent an overload on the generator when it is supplying the customer loads (see Figure

1.2). Up to six loads can be managed by the LSM; 2 air conditioner loads and 4 other loads. The LSM manages the loads by

“shedding” the connected loads in the event of a drop in generator frequency (overload). Loads to be “shed” are grouped in 4 priority levels on the LSM.

• Priority 1 and 2 has connections for both one air conditioner and one contactor. Both an air conditioner and a contactor can be used at the same time if desired. To control an air conditioner, no additional equipment is required. Internal relays interrupt the thermostat 24VAC control signal to disable the air conditioner load.

• Priority 3 and 4 have connections for one contactor only.

• Four LEDs, located on the load shed module, will indicate when a load priority level is enabled.

• Any loads, including central air conditioners, can be controlled via a contactor that must be purchased separately. Up to four contactors can be controlled by the load shed module. The LSM supplies the 120 Vac to energize each contactor coil.

• Generator overload condition is determined by generator frequency. Loads are shed when the frequency is <58Hz for 3 seconds or <50Hz for ½ Second (For 60Hz).

The LSM has a Test button which forces the unit to act as if an overload has occurred. This button operates even when the transfer signal is inactive.

1.6 SAFE USE OF TRANSFER

SwITCH

Before installing, operating or servicing this equipment, read the

SAFETy RULES (inside front cover) carefully. Comply strictly with all SAFETy RULES to prevent accidents and/or damage to the equipment. The manufacturer recommends that a copy of the

SAFETy RULES are posted near the transfer switch. Also, be sure to read all instructions and information found on tags, labels and decals affixed to the equipment.

Three publications that outline the safe use of transfer switches are the following:

• NFPA 70; National Electrical Code

• NFPA 70E; Standard for Electrical Safety in the Workplace

• UL 1008, STANDARD FOR SAFETy-AUTOMATIC TRANSFER

SWITCHES

NOTE:

It is essential to use the latest version of any standard to ensure correct and current information.

2.1 INTRODUCTION TO

INSTALLATION

This equipment has been wired and tested at the factory. Installing the switch includes the following procedures:

• Mounting the enclosure.

• Connecting power source leads and load leads.

• Connecting the generator sensing and transfer relay circuits.

• Connecting any auxiliary contact (if needed)

• Connect load shed module loads (as required)

• Testing functions.

2.2 mOUNTING

Mounting dimensions for the transfer switch enclosure are in this manual. Enclosures are typically wall-mounted. See “Installation

Diagram”.

‹

Handle transfer switches carefully when installing. Do not drop the switch. protect the switch against impact at all times, and against construction grit and metal chips. Never install a transfer switch that has been damaged.

This transfer switch is mounted in a UL type 3R enclosure. It can be mounted outside or inside and should be based on the layout of installation, convenience and proximity to the utility supply and load center.

3

Installation

Install the transfer switch as close as possible to the electrical loads that are to be connected to it. Mount the switch vertically to a rigid supporting structure. To prevent switch distortion, level all mounting points. If necessary, use washers behind mounting holes to level the unit.

2.3 CONNECTING pOwER SOURCE

AND LOAD LINES

+

make sure to turn OFF both the UTILITY

(NORmAL) and GENERATOR (STANDbY) power supplies before trying to connect power source and load lines to the transfer switch.

Supply voltages are extremely high and dangerous. Contact with such high voltage power supply lines causes extremely hazardous, possibly lethal, electrical shock.

Wiring diagrams and electrical schematics are provided in this manual.

NOTE:

All installations must comply with national, state and local codes. It is the responsibility of the installer to perform an installation that will pass the final electrical inspection.

The utility supply connection is made at the UTILITy SERVICE DIS-

CONNECT circuit breaker terminals. The generator and customer load connections are made at the transfer switch mechanism, inside the switch enclosure.

Conductor sizes must be adequate to handle the maximum current to which they will be subjected, based on the 75°C column of tables, charts, etc. used to size conductors. The installation must comply fully with all applicable codes, standards and regulations.

All power cables must enter the enclosure through the knockouts provided. If not using the knockouts, conduit entry into the enclosure must be at or below knockouts to maintain the Type 3R rating.

Conduits should be arranged to provide separation between the

Utility and Generator supply conductors inside the enclosure.

Before connecting wiring cables to terminals, remove any surface oxides from the cable ends with a wire brush. If ALUMINUM conductors are used, apply corrosion inhibitor to conductors. Tighten terminal lugs to the torque values on "Utility Service Disconnect

Circuit Breaker", and on the decal located on the inside of the door.

After tightening terminal lugs, carefully wipe away any excess corrosion inhibitor.

‹

Use a torque wrench to tighten the conductors, being sure not to overtighten, or damage to the switch base could occur. If not tightened enough, a loose connection would result, causing excess heat which could damage the switch base.

Connect power source load conductors to clearly marked transfer mechanism terminal lugs as follows

UTILITy (NORMAL) power source cables to UTILITy

SERVICE DISCONNECT circuit breaker.

2. Connect the GENERATOR (STANDBy) source power cables to switch terminals E1, E2.

3. Connect customer LOAD leads to switch terminals T1, T2.

Conductors must be properly supported, of approved insulative qualities, protected by approved conduit, and of the correct wire gauge size in accordance with applicable codes.

Be sure to maintain proper electrical clearance between live metal parts and grounded metal. Allow at least 1/2 inch for 100-400 amp circuits.

2.4 CONNECTING START CIRCUIT wIRES

Control system interconnections (Electrical Data section) consist of UTILITy 1 (N1), UTILITy 2 (N2) and LOAD (T1), and leads 23, 0 and 194. Recommended wire gauge sizes for this wiring depends on the length of the wire, as recommended in the following chart:

2.5 CONNECTING LOAD SHED mODULE (LSm) CONNECTION

The LSM can control an air conditioner (24 Vac) directly or a separate contactor (120 Vac) which can control any load connected to it. See Figure 2.1.

2.5.1 seqUence of operation

The 4 green status LEDs will indicate when a load priority level is enabled.

• All loads are enabled when the transfer signal is off. (ATS in

Utility position).

• If the transfer signal is pulled low (Active)

• All loads are enabled until an overload is detected

• When an overload is detected all loads are disabled

• After 5 minutes priority 1 loads are enabled.

• After another 30 seconds priority 2 loads are enabled

• After another 30 seconds priority 3 loads are enabled

• After another 30 seconds priority 4 loads are enabled

If an overload is detected within 30 seconds of a level being enabled, all loads are disabled again and the sequence repeats.

However, the level that caused the overload and all levels higher will not be enabled again for 30 minutes.

24 VAC, 5.0 Amps Max

NOTE:

These instructions are for a typical air conditioner installation.

Control of heat pump and 2-stage air conditioners will require special connections.

Control of a Separate Contactor

A separate contactor relay module can be purchased from the manufacturer. If a different relay is used it must have a 120 Vac coil voltage. The LSM supplies a fused (5A) 120 Vac to energize the coils of the relay contactors (L1, L2, L3 and L4).

1. Mount the contactor module and connect the load to the main contacts.

2. Connect the contactor coil to the desired LSM L1-L4 terminals on the terminal strip.

3. Connect additional load shedding contactors in a similar fashion.

NOTE:

It will be necessary to determine the order of “shedding” the connected loads and connect the loads to the lSM in that order.

One is the highest priority and four is the lowest priority.
