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 MR-GW is intended for fixed installation and operation inside enclosed rooms in electrical
distribution boards and suitable control panels. The MR-GW 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.
