LCD Control Panel (1000W version only)
This panel and the CANCEL, SCROLL and SELECT buttons below it let you monitor and
control the UPS. More information is given in Section 3, “Operation.”
6
Battery Voltage Test Points (1000W version only)
These let you measure the battery voltage. They accept 2mm diameter test probe tips. The
battery circuit breaker must be on to measure the voltage. NOTE: It is not a power outlet.
7
RS-232 Port
This DE-9 female connector allows you to use a straight-through DB-9 to DE-9 connector
computer cable to connect the UPS to a computer for remote control and monitoring. More
information is given in Section 4, “Communication.”
8
Battery Temperature Sensor
This connector accepts the battery temperature probe from the battery so that the UPS
can monitor the battery temperature. The charging voltage is temperature dependent and
the UPS’s microprocessor adjusts it for optimum charging.
The probe MUST be attached to the UPS for normal operation. Firmly attach the sensor
end to the centre battery’s case with high-strength ameproof tape (such as duct tape)
as shown in Section 2.3, “Wiring the UPS.” Otherwise, a “Temperature Probe Unplugged”
alarm will appear on the LCD. See Section 3.6, “Troubleshooting”, “Temp Probe
Unplugged”.
9
User Input C7 (1000W version only)
This optically isolated input let you attach an external switch panel for remote control of the
UPS (Figure 1.3.5).
19 (S1): Shorting this contact starts the UPS’s self test. Also see Section 3.4, “Battery Test.”
20 (S2): Shorting this contact activates an alarm. Also see Section 3.6, “User Input Alarm.”
21 (S3): Shorting this contact shuts down the inverter and disconnects the input voltage. A manual
restart is required to put the UPS back to normal operation.
22 (C): Isolated return for contacts S1, S2 and S3.
