Appendix 2 Parallel board signals
The parallel board has three sets of signals:
■ CAN bus (DB9) connectors. These must be connected as described in Wiring units in parallel on
page 12.
■ LBS (Load Bus Synchronisation) connectors. These may be used for a particular system
configuration as described below.
■ Optional dry contact relay signals described below.
LBS (Load Bus Synchronisation)
It is possible to synchronise the output of two separate paralleled systems, where each system can
consist of up to 4 paralleled units. It is only necessary to connect UPS number 1 of each system.
To do this, connect the LBS1 (pink) connector of system A to the LBS2 (green) connector of system B.
The LBS connectors are 3.5 mm 3-pole jack sockets.
Dry contact relay signals
To wire to the signals you will need:
■ A Molex connector, part no. 39-01-2120 (94V-2) or 39-01-2125 (94V-0).
■ Crimps (part no. 39-00-0039)
As an option you may want to fit a strain relief, part no. 15-04-0345 (94V-2).
Connections:
Pin no. Signal name Description
1 12V Provides a +12 V 100 mA isolated supply
2 GND Common return (0 V) for the +12 V supply and relays. This is not
connected to the chassis.
3 Remote ON Connect to +12V to turn on the UPS (pulse contact)
4 Remote OFF Connect to +12V to turn off the UPS (pulse contact)
5 EPO Emergency power off connect to +12V for complete power off (pulse
contact)
6 BAT_T4 Over temperature switch on battery 4. Feed +12 V via the switch
when the battery temperature is exceeded.
7 BAT_T1 Over temperature switch on battery 1. Feed +12 V via the switch
when the battery temperature is exceeded.
8 BAT_T2 Over temperature switch on battery 2. Feed +12 V via the switch
when the battery temperature is exceeded.
9 BP-C Anti-backfeed relay common
10 BP-O Anti-backfeed relay normally closed.
To prevent the input being energised by backfeeding in the event of
an internal failure, connect this signal to an external circuit breaker
trip.
11 BP-S Anti-backfeed relay normally open.
To prevent the input being energised by backfeeding in the event of
an internal failure, connect this signal to an external circuit breaker
trip.
12 BAT_T3 Over temperature switch on battery 3. Feed +12 V via the switch
when the battery temperature is exceeded.
