Pin
Description
1, 9
GND of SNMP card
2
SNMP card power provided by DSP panel
3
Signal from the SNMP card, which connects with RXD of the DSP
4
Signal to SNMP card, which connects with TXD of the DSP
5
Connect with RX of the RS232 communication port of the host
6
Connect with TX of the RS232 communication port of the host
7
Reserved
8
Selected communication signal, +9_TR is introduced into this pin after the SNMP card is plugged
10
The power supplied by DSP panel, for selecting the card
Note
If you wish to connect the SNMP card (model: UF-SNMP810) to Emerson temperature sensor (model: RDU-A-S01T) to make it be
the battery temperature compensation, please connect the COM1 port of the SNMP card, and set the temperature sensor DIP
address to ‘1’.
Warning
The DIP switch on the UPS front panel (see Figure1-1) is used to set the parallel address for each UPS single in parallel system
installation. You are not required for setting the DIP switch in UPS single system installation. Set the DIP switch at will can result in
UPS fault!
2.8 Parallel System
The UPS parallel system provides the user with N + X (2≤N + X≤4) parallel configuration, N stands for the basic
parallel sets, X stands for the redundant sets.
The UPS parallel system has 1 + 1 parallel POD options, which can provide safe and reliable distribution function for
parallel system. The 1 + 1 parallel system only needs one 1 + 1 parallel POD; if N≥2, the self-distribution will be
required for the parallel system.
Parallel system installation includes:
• Mechanical installation
• Setting parallel addresses
• Parallel cables connection
• 1 + 1 parallel POD cables connection
2.8.1 Mechanical Installation
Taking the rack installation of the 1 + 1 parallel system including battery module for example, the mechanical
installation method of the parallel system is as follows:
1. The installation method of 1 + 1 parallel POD is the same as that of the UPS. Refer to 2.4.2 Rack Installation for
details.
2. As shown in Figure 2-18, the battery module should be installed at the bottom, the UPS should be installed in the
middle, and the 1 + 1 parallel POD should be installed on the top, so as to facilitate the cable connection and
operation.
