4. Battery Charge Discharge CAUTION To prevent battery discharge prior to system operation do not con nect the battery to the PS BC until the AC power is connected or imminent Each battery has a hardwired 6 foot battery charge discharge wire that originates at the battery housing and terminates at a modular connector The PS BC has two mating connector ports each labeled 48V 3A INPUT It does not matter which battery connects to which port To prevent heat buildup the battery charge current is limited to 1 amp per battery This elimi nates the need for temperature compensation Alarm Wiring The alarm relay output originates at a modular connector with a 6 foot wire stub Wiring termination of the output is customer designated The alarm outputs AC Fail Battery Low Voltage are assigned the following wire color codes e ACF orange orange white e BV blue blue white OPERATION The PS BC starts operation when AC or battery power is applied During operation ambient temperature can increase up to 50 C without affecting output If ambient temperature increases beyond 50 C output must be derated At 70 C ambient output load is limited to 5 amps CAUTION External PS BC surfaces can become hot during operation above 50 C ambient temperature MAINTENANCE The Total Access PS BC does not require routine maintenance for normal operation ADTRAN does not recommend that repairs be attempted in the field Repair servi
5. PP NN 2 61180043L2 5D Description Ca QC Battery Disconnect Protection Circuit During battery operation a protection circuit disconnects battery from the main output when battery voltage drops below 39 VDC preventing over discharge When AC returns the main output provides regulated 54 VDC batteries recharge and the system returns to normal Refer to LED Indication After the protection circuit initiates the LEDs remain on red continuing to slowly drain the battery When battery voltage drops to 35 VDC all load is removed from the battery If AC power will not be available for an extended period several days disconnect the battery to prevent unnecessary discharge DC Over Voltage Protection The PS BC has a protection circuit that disables the rectifier to protect the load from a high output voltage caused by rectifier failure The backup battery or redundant PS BC supports the load in this instance The over voltage event can permanently disable the PS BC Confirm this by performing the following procedure 1 Disconnect the PS BC from the AC source 2 Wait 30 minutes minimum 3 After 30 minutes plug back into the AC source A If the unit has recovered the AC FAIL UNIT FAIL OVERLOAD LED will turn on green and the unit returns to service If the LED does not turn on green replace the PS BC Alarm Relays There are two uncommitted alarm relays associated with PS BC operation e AC Fail ACF Alarms if AC
