Installation Instructions
1. Mount cabinet per mechanical dimensions and knockout locations given in Section IV.
2. Connect 120VAC, 60Hz., single phase to the black and white leads of the transformer in accordance
with Article 725 or Article 760 of the National Electrical Code or Article 16 or 32 of the Canadian
Electrical Code.
3. Low Volt AC Input - Connected to secondary winding of the transformer.
v
Fused at 10 Amps (Fuse Type AGC-10)
4. Verify output voltage at "DC Output" and "Battery" terminals.
12V system measures approximately 13.8VDC.
24V system measures approximately 27.6VDC.
5. Connect battery set to "Battery" terminals.
CAUTION: Observe polarity; incorrect polarity will destroy battery fuse.
Fused at 10 Amps (Fuse Type AGC-10).
Recommended battery type - PowerSonic (PSSeries) or YUASA (NPSeries) sealed lead acid/gel cell.
The Battery terminals are Nonpower limited. Wiring of the batteries must conform to the Power Limited
Wiring Requirements in Section V, and to Article 760 of the National Electrical Code or Article 16 of the
Canadian Electrical Code.
6. Connect "DC Output" to input of user system.
CAUTION: Observe polarity; incorrect polarity may damage user system.
Refer to Section I for Maximum Allowable System Current.
Output terminals are POWER LIMITED
7. Visual Indicators:
AC Presence LED1:
Green LED
System OK LED3:
Green LED
LED2 (Red LED) serves no user function.
8. Connect "Fault Output" to system fault annunciation.
Form "C" Relay Contacts rated 1 Amp @ 24VDC resistive
Relay Contacts labeled in the non-operational (fault) condition.
Fail-safe; active until an actual fault condition.
9. Fault Conditions:
Low AC / No AC / Blown AC Fuse / Low Battery / Blown Battery Fuse
CAUTION: Fault condition reporting may be delayed dependent on power supply loading.
The battery set is NOT supervised for presence.
10. Battery Standby Information:
a) For 60 hr. standby with 36Ah battery set - Max standby draw: .5A, Max 5 minute alarm current: 2A.
b) For 24 hr. standby with 36Ah battery set - Max standby draw: 1A, Max 5 minute alarm current: 2A.
c) For 4 hr. standby with 20Ah battery set - Max standby draw: 2.5A, Max 5 minute alarm current: 2.5A.
11. Power Supply System Draw (No AC, No load) is 25mA.
