Communication Interfaces

18.1

Remote Contacts

The remote contacts interface is provided as a set of solid state switching devices. The switches are available through a
DB9 male connector on the rear of the UPS. The following chart shows the pin assignment for each signal.
MAXIMUM CURRENT CARRYING CAPACITY
Voltage
48 Vdc peak
30 Vac rms
(42 Vac peak)
Pin Signal Function
1 Fault Signal
2 UPS stop common
3 UPS stop signal input
4 Normal input power supply
5 Signal common
6 Bypass operation
7 Battery voltage drop
8 UPS operation
9 Power failure signal
NOTE: Pin switches are shown in their inactive states. For example, if battery voltage is low, pin 7 will be connected to pin 5.
1: When not applying +3 to +15V, the voltage supplied to pins 2 and 3 should be reverse biased (-3 to -15V) to avoid
unintentional closure due to signal noise.
