TS_622_02 PowerWAVE 9500DPA User Manual 26/2/19
A customer interface board, which is fitted to the front right-hand side of each UPS cabinet, provides various means of
connecting ‘cabinet’ and ‘system’ level UPS monitoring and control interfaces to external devices
(see Figure 9.1)
.
The customer interface board connections include:
• Dry-port inputs for customer remote control options (X3).
• Relay operated dry-port alarm outputs for remote monitoring (X2).
• RS232 computer interface for remote monitoring/control applications (JD1)
• RS232 computer interface for multidrop (JR2)
• USB port for computer monitoring applications
• An SNMP/CS141 card slot
• An SNMP slot for Modem/Ethernet card
9.2.1 Serial RS-232/ USB Computer interface – JD1 & USB (Smart Port)
JD11 is an intelligent RS 232 serial port which allows the UPS cabinet to be connected to a computer for monitoring
purposes. Its connector is a 9-pin female D-type and it can be connected to a computer using standard computer serial
communications cable wired as shown below in Figure 9.2. The maximum length of the RS232 cable is 15m.
When used in conjunction with suitable software, this port allows the connected computer to continuously monitor the
input mains voltage and UPS status, and display a message if there any UPS system changes.
The USB port on the customer interface board is connected in parallel with JD11 and output the same data stream.

9.2.2 Dry ports customer interface (X2, X3)
Customer I/O interface facilities are made to Phoenix spring terminal blocks (cable 0.5 mm² to 1.5 mm²). All voltage-free
contacts are rated at 250VAC/8A, 30VDC/8A, 110VDC/0.3A, 220VDC/0.12A.
On the Master board the following ports are active:
• The Input ports (X2)
• The Output port (X3)
On the Slave boards the following parts are active.
• The Output ports X2
• All other input or output ports on the Slave boards are not activated
Key Point:
If the UPS is operating as a parallel cabinet system and the ‘Multidrop’ application is enabled, the
customer interface board I/O is disabled in the ‘slave’ cabinet(s) and the interface connections should be made
on the customer interface board fitted in the ‘master’ module only.
