Problems
Action to take
1
The dry contact output signal does not change with the
UPS status
Verify that the relay card is properly inserted into the
Intellislot port
2
The UPS does not respond to the UPS turn-on dry contact
input signal
Verify that bit 8 of the DIP switch of the relay card is
placed in the “ON” position
8.2.9 Modbus Card
The Modbus card can realize the conversion from UPS internal protocol to Modbus RTU protocol, so you can use
your host monitoring software to manage your UPS through Modbus RTU protocol, to learn about the UPS operating
status by acquiring the UPS electrical parameter data, operating data and alarm data, thus achieving UPS monitoring.
One UPS can be fitted with up to two Modbus cards, which allows you to monitor the UPS through multiple hosts.
For the installation and setting of the Modbus card, refer to
UPS JBUS/MODBUS Adapter User Manual
.
8.2.10 SiteMonitor Monitoring Software
SiteMonitor monitoring software is designed to monitor the UPS (UH11, US11R, UH31, UL31, UL33, 2G, Nfinity, NX,
Hipulse, Hipulse U), air-conditioner (CM+, DataMate3000, DME, Deluxe), and LTS series STS developed by
Emerson. It can also perform centralized monitoring over various ambient signals, such as temperature, humidity,
smoke and fog, water logging, infrared, through optional equipment developed by Emerson, like UPS ambient signal
adapter.
SiteMonitor can run on Windows, Linux, Solaris, AIX and HP-UX operating systems. It is accessed with a Web
browser. You may use any computer over the network to log in SiteMonitor to conduct equipment monitoring and
maintenance management.
For the installation and operation of the SiteMonitor monitoring software, refer to

8.2.11 Common Input Assembly/Cable/Copper Bar
For UPSs in common input configuration, a common input assembly/cable/copper bar option is required to short the
main input terminals with the bypass input terminals of the UPS. This option is fitted in factory.
8.2.12 Common Battery Assembly
The common battery assembly is a requisite part designed to ease the user wiring. The battery input cables should
be connected to the copper bar of the common battery assembly, and then the flexible cables of the assembly
transmit the battery current to the battery terminals of each power module. This requisite part is fitted in factory.
8.2.13 Maintenance Switch Assembly
The assembly is a part designed for the user who has not prepared external maintenance switch for the external
distribution cabinet. First use M8*50 screws (4 pcs) and M10*30 screws (18) to install the switch (16010161) in the
bypass cabinet, and then install the auxiliary contact, extension bar, label, handle and cover board in turn. Installed in
factory, this assembly is applicable to 600kVA and 800kVA UPSs.
8.2.14 No Switch Assembly
This assembly contains the connection copper bar, and is optional for 500kVA ~ 600kVA E UPS. If the user selects
the cabinet without switch, then this assembly is a must. Note that this option is fitted in factory.
8.2.15 Two Switches Assembly
This assembly contains the connection copper bar, Q2 and Q5, and is optional for 500kVA ~ 600kVA E UPS. If the
user selects the cabinet with two switches, then this assembly is a must. Note that this option is fitted in factory.
