*NiCad Battery Charge Parameters
Caution! When configuring for NiCad use, the Battery Charging Level adjustment on front panel must be set to at least 30%
of the capacity of the battery being charged (ie at least 30% of battery rated Amp-Hour capacity), (Note, the adjustment
range of Battery Charging Level dial on the unit is 4 amps minimum, 20 amps maximum.)
If set below the prescribed 30% minimum Ah capacity, the control circuit may not be able to sense battery absorption
rate, and thus not terminate absorption charge cycle until 16 hours has passed, potentially resulting in battery overcharge.
Float Charge: Constant current, rate =10% of the set Battery Charging Level
Absorption Charge: 28.0 VDC (1.4 VPC x 20 cells).
Termination of absorption charge is determined by an automatic battery test applied after entering absortion mode:
• If test indicates battery will not maintain its voltage (ie drops by > 0.1 volts) absorption mode will continue for a
maximum 16 hours before reverting to float mode.
• If test indicates battery voltage is maintained (i.e. drops <0.1 volts), absorption mode times out after 10 minutes, and reverts to float mode.

• Shorted Cell
Jumper inserted into position 7 making all power from the unit
available for battery charging by disabling the load priority
output function. Under low battery charge condition, output
voltage to load will be equal to that of the battery voltage, thus
useful voltage to the load will not be available until the battery
recovers to proper levels.
1) General Information
This DIN rail mount DC UPS Combines all system power functions: power supply, battery charger, UPS circuitry and status
monitoring in one compact unit that produces 24 volt, 20 amps allocated via dual outputs for load and battery:
• Load output: “load priority” distribution ensures power is dedicated first to the load, with remainder then allocated to
battery charging, thus preventing a discharged battery from impacting operation of critical loads.
• Battery output: 3 step charging for rapid battery recovery, programmable for battery type, with optional temperature
compensation sensor
• Battery automatically on line to support load anytime AC fails
• Low voltage disconnect protects battery from total discharge
• Automatic periodic battery health diagnosis
• High operating temperature range to 70˚ C
• Alarm contacts: AC fail, battery status/condition
Materials Provided:
1 ea. DIN-UPS unit with integral DIN rail mount clip
4 ea. Jumper tabs for programming
1 ea. Jumper wire (orange) for 115 volt input operation
Optional Equipment:
Temperature Compensation Sensor, P/N: 468-4510-0
2) Safety Information
WARNING – Explosion Hazard. Do not disconnect loads or battery unless AC input and battery have been
switched off.
WARNING – Explosion Hazard. Substitution of components may impair suitability for class I, Division 2.
WARNING – Switch off or remove AC input and battery power before wiring the DIN-UPS 24-20. Never work
on the DIN UPS when it is connected to AC input and battery. The DIN UPS must be installed in accordance
with UL508 or local electrical codes depending upon the application. The DIN UPS should have a suitability sized AC input
circuit breaker feeding its AC input. See specification section for maximum AC input draw for your input voltage for circuit
breaker sizing.
CAUTION: Hot surface. Avoid touching the DIN UPS case while operating at or near its full load capacity. Remove AC and
battery power and allow DIN UPS at least 10 minutes to cool before removing from DIN Rail.
3) Installation/Wiring
A) Mounting:
The unit is designed for 35 mm DIN rail mounting in an enclosure and relies on convection (free air) cooling, thus must
have a minimum 4” (10 cm) of open space above and below DIN UPS in order to assure sufficient air flow. We recommend
approximately 1/2” (10mm) spacing between adjacent DIN Rail mounted devices. Note, that depending on the ambient
temperature and load of the device, the temperature of the case can become hot to the touch.
4
The unit is designed for vertical mount (+/- 5˚) and has an integral clip on the back to secure it to the rail. To mount, place
the top tabs over the top of the DIN rail, and using a long slotted screw driver insert it in the groove at the bottom of the
bracket and twist which will extend the spring loaded mounting bracket downward allowing the unit to be positioned
against the DIN rail, release the bracket with DIN UPS positioned vertically and the rail will be captured and the unit
secured.

The unit has dual output circuits: one for connection to the Load, the
other to the back-up battery. Note: the unit has a load priority circuit,
all produced power first is made available to the load with remaining
power made available for battery charging. Both outputs are isolated
from the case.

Fuse note: We recommend a 25 amp fuse be installed on the hot leg at battery. If using
both sets of battery terminals on DIN UPS (i.e. two pairs of wires, recommended for long
wire runs), connect both hot wires to one side of battery fuse.

C) LVD)
The unit contains a low voltage load disconnect that activates at 18 volts (1.5 vpc) which is factory set and cannot be user
modified. (See also Section 4-C regarding operation with battery time out circuit)
6) Protection
On the AC Input: the device is equipped with an internal fuse. If the internal fuse is blown, it is most probable that there is
a fault in the unit. If this occurs, the unit must be returned to the factory.
On the DC Ouput Battery and Load: The device is electrically protected.
Reverse polarity: the module is automatically protected against reverse of battery polarity and connection of reverse
polarity.
Over current and output short circuit: the unit limits the output current. Low voltage disconnect protects battery from deep
discharge.

Thermal protection
Operating temperature range -12 to 70˚ C. Unit will produce full rated power on continuous basis to 50˚ C, however;
system load must be reduced by 2.5% per 1˚ for continuous operation above 50˚ C. If the temperature reaches 70˚ C, the
unit will reduce its maximum output to approximately 50% of its rating. If the temperature exceeds 70˚ C, the unit will shut
off and restart once temperature drops.

8) Troubleshooting
Symptom
Possible Cause
Corrective Action
1.Reduce load or split load between
two separate DIN UPS units
A. Battery requires excessive
re-charge time
1.Load at or near max.
recommended load providing
minimal current available for
charging
2.Charging level current set to low
2.Adjust “Battery Charging Level”
control knob to higher level
1.Time buffer set to incorrect position
1.Verify correct setting with manual
2.Batteries not charged, due to high
load demand
2.Reduce load or split load between
two separate DIN UPS units
1. Absorption jumper not installed
1. Install provided jumper in
position 6
D. Unit does not turn on
1. AC input is 115 VAC, no
jumper wire installed
1. Install 115V jumper wire across j1
and j2
E. Trips AC input breaker
1. AC shorted to case
1. Verify correct AC input wiring
2. Defective unit
2. Contact technical service
1. DC output wired backwards
or shorted
1. Remove AC input and check DC
wiring
2. No AC input
2. Verify correct AC input and
jumper wire installed if powering
from 115 VAC
3. Excessive temperature or
blocked ventilation
3. Improve ventilation, unblock
vent holes
4. Defective unit
4. Contact technical service
1. No battery installed (voltage
required for battery output to
turn on)
1. Install batteries
2. Missing or blown battery
wiring fuse
2. Replace missing or blown battery
wiring fuse
1. Normal operation
1. Refer to Chart 2: Diagnosis Table
B. Load turns off after a couple
of seconds when running
on battery
C. No absoprtion voltage
F. No output
G. No voltage on battery
output terminals
H. Diagnosis LEDs always blinking
