3Installation
3.1 Installation location and state
The electrical installation and device connection may only be carried out by qualified personnel in
compliance with VDE regulations and local regulations. Before working on the system, it must be
disconnected from the power supply. The BMT-RTR is intended for fixed installation and operation inside
enclosed rooms in electrical distribution boards and suitable control panels. The BMT-RTR is designed
for mounting on TH35 mounting rails in accordance with IEC 60715. It can be installed in any position.
Horizontal installation is recommended. It is possible to add them to other control cabinet components
without spacing.
3.2 Mounting
The BMT-RTR is suitable for decentralized mounting in electrical sub-distribution boards or in switch
cabinets on TH35 mounting rails according to IEC 60715. The BMT-RTR can be snapped onto a TH35
mounting rail according to IEC 60715 for installation in an electrical distributor or small enclosure. The
device has to be accessible for operating, testing, inspection and maintenance.
Figure 1 Mounting of BMT-RTR
3.3 Dismounting und disposal
Before disassembling, it must be ensured that the BMT-RTR has been taken out of operation and that
all supply lines are de-energized. Once all supply lines have been removed, use a slotted screwdriver to
move the bolt on the BMT-RTR outwards and remove the device from the mounting rail.
