Automation DC Power • Powering the Network
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 fi rst 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 specifi cation 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 suffi cient air fl ow. 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.
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.
Function Setting
Battery Test ON
Insert Jumper: Pos. 4
Pos. 4
Insert jumper at position 4 to enable Periodic Battery condition
test process. (Fault reported by LED diagnosis blink code, see
Table 6):
•
Battery wiring connection
•
Battery efficiency/sulfation (impedance tesst)
•
Shorted Cell
Load Priority Disable
(Makes full power
available
for charging)
Insert Jumper: Pos. 7
Pos. 7
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.
