Place your unit in the desired location for use. Connect all equipment power cords to the receptacles on the rear of the UPS. Please insure you confirm total power requirements and do not overload the units.
Press and release the main power switch on the front of the unit to turn on the unit. Press and release again to turn off the unit. Some models have a circuit breaker on the rear panel that must be turned ON first and then press the front panel switch to turn the unit ON.
The unit will turn on, perform a self diagnostic test, switch to bypass mode and then turn on to full inverter mode automatically.
ALARMS
ON BATTERY
When the UPS is operating in the battery mode, the Battery Mode Icon will illuminate and the audible alarm will sound every 10 seconds. The alarm will stop and the Battery Mode Icon will extinquish once the UPS returns to AC normal operation.
UPS FAULT
When the UPS detects a fault, the Unit Fault Icon will illuminate and the UPS will emit a sustained tone. The unit will also display a failure code if available. (see section 5 Trouble- shooting for failure code definition)
OVERLOAD
When the amount of load attached to the UPS exceeds its power rating, the Unit Overload Icon will illuminate and the UPS will emit a sustained tone. This alarm will remain on until the excess load is removed or the UPS’s self protection circuit takes control. If the unit self protection circuit takes control, the unit will switch to bypass mode until the overload is removed. If the load is excessive, the input circuit breaker will open and the unit will shut down.
REPLACE BATTERY
The UPS automatically tests the battery’s condition and will illuminate the Unit Battery Icon and emit a short beep. This tone will be repeated every hour until the batteries passes a self test. It is recommended that the UPS be allowed to charge overnight before performing a battery test to confirm a Weak/Bad Battery condition.
LOW BATTERY WARNING
The UPS will emit two consecutive beeps every five seconds when the battery reserve runs low. This continues until AC returns or the UPS shuts down from battery exhaustion.
COMMUNICATIONS PORT
Communications port information for 700VA and 1000VA units only:
The communications port is a standard DB9 female with both RS232 and relay contact closure capability. The units will poll the port and activate the port for RS232 or contact closure in accordance with the type of cable it finds connected to the port. To change the port configuration requires the unit be turned off and restarted with the desired cable connected. The pinout for the port is depicted per the chart below.
Pin 1: | Instant off ( pull and hold this pin low to turn off output receptacles) |
Pin 2: | /TXD |
Pin 3: | /RXD and receive ups shutdown command |
Pin 4: | AC fail, NO closes on event |
Pin 5: | Ground |
Pin 6: | Low battery warning, NO closes on event |
Pin 7: | Common return for all relays |
Pin 8: | Summary alarm, NO closes on AC fail, low battery warning, overload, UPS failure |
| or unit on bypass |
Pin 9: | Not Used |
