e.g.: line1/line 2 ready for operation, Q1 on / Q2 on. The values can be assigned via the
menu of the control device (see instruction leaflet PRC487).
• Switching back interlocking: On recovery of the voltage, switching back to the preferred
supply line can be disabled or enabled via an external contact. Please observe the requi-
rements of DIN VDE 0100-710 (VDE 0100 Part 710):2002-11 Abs. 710.537.6.1.f)

Instruction for connection
3.3.1 Alarm indicator and test combination
Ex works, the following pairs of terminals are provided for the connection of BMS bus devices:
X3:29 and X3:30 (A/B)
X3:31 and X3:32 (A/B terminals are terminated with 120 Ω at the factory)
Alarm indicator and test combinations, panels and other Bender-BMS-bus devices can be connec-
ted.
1. A BMS device or an existing BMS bus with several devices is connected to terminals
X3:29 and X3:30:
The last device at the other end of the bus must be terminated with 120 Ω. Terminals
X3:31 and X3:32 remain terminated.
2. An existing BMS bus that has already been terminated on both ends, is disconnected;
one open branch is connected to terminals X3:29 and X3:30, while the other one is con-
nected to terminals X3:31 and X3:32:
The 120 Ω resistor, provided ex works, must be removed and the open bus branches
must be connected to the specified terminals.
Please read the information on cable routing in the „BMS bus“ instruction leaflet.
The AN450 power supply unit can supply power to a maximum of 2 MK2430 alarm indicator and
test combinations via the terminals X3:33 and X3:34. In this respect, please refer to the documen-
tation for the relevant devices. The AN450 is not suitable for supplying power to TM... operator
panels.
3.3.2 TMX-HA
Connect the alarm indicator and operator panel TMX-HA to the terminals X3:39 ... X3:70 of the
changeover module UMC . 710D4-..-HA. The panel is supplied via the power supply unit AN450
via the terminals 33 and 34.
3.3.3 GLT/ZLT
If messages from the UMC710D4-.. changeover module are to be transmitted to a Building
Control System or to a Central Process Control System, you have the following options:
• Protocol converter (gateways)
• OPC server
• Common alarm via the relay outputs of the PRC487 control device
• Conversion between BMS bus and digital inputs and outputs by means of alarm indica-
tor and operator panels (TM...) or signal converters (SMO480-12, SMO482-12, SMI 473-12.
