Introduction
Figure 7.1 UPS Interface board (DPA-50 details shown)
Each UPS cabinet is fitted with an interface board, as shown in Figure 7.1, which enables various external monitoring and
control applications to be connected to the UPS system to satisfy particular site requirements. The interface board’s input
and output connections are shown above in Figure 7.1
The interface board has two LEDs:
• The green LED indicates the status of the interface and blinks twice per second when the board is fitted to the
‘master’ UPS (1st cabinet in the parallel system), and once per second when the board is fitted to a ‘slave’ UPS.
• The red LED is an alarm indication and illuminates to indicate a possible faulty board.
The following ports are active on the interface board when fitted to the ‘master’ UPS cabinet:
• The Input ports (X1)
• The Output port (X2, X3, X4)
The following ports are active on the Interface Board when fitted to a Slave cabinet:
• The Output ports X3/6 … X3/10
• The Output ports X4/1 …X4/10 (Means Alarm. Module 1, 2, 3,4, 5)
• All other input or output ports on the Slave boards are not activated
These interfaces are described below.
• Dry port customer interface – X1 (customer inputs), X2-X4 (customer outputs)
(see paragraph 7.2)
• RS232 Computer serial interface – USB & JD11
(see paragraph 7.3)
• RS232 Interface for multidrop – JD12
