NOTE

The emergency stop action within the UPS shuts down the rectifier, inverter and static bypass. It does not internally disconnect the input power supply. To disconnect ALL power to the UPS, open the upstream feeder breaker(s) when the remote EPO is activated.

NOTE

Normally closed EPO – X2: 1,2, these terminals are supplied factory-linked on the monitor board and must remain installed if using NC contacts.

NOTE

All auxiliary cables of terminal must be double insulated. Wire should be 0.5-1.5mm2

(16-20AWG) stranded for maximum runs between 25 and 50 meters (82-164ft.) respectively.

X5: Auxiliary DC Power Output

Auxiliary DC power for modem or external SNMP card. The voltage is between 9V to 12V. The maxi- mum current is 500mA.

X6: Analog Input Interface

Two analog signal channels with an input range is from 0 to +12V. The precision of detection is ÷3%.

•X6 pin 1: Not used

•X6 pin 2: +12V

•X6 pin 3: ENV-T – environment temperature detection

•X6 pin 4: GND

X7: External Battery Temperature Detector Interface

Interface for TMP12Z temperature detector, normally connected to an external battery cabinet (see Figure 26).

Pin reference:

•X7 pin 1: Not used

•X7 pin 2: +12V (Power supply for Temperature Monitoring Probe)

•X7 pin 3: BAT-T (Battery Temperature signal)

•X7 pin 4: GND
