Keep away from high voltage lines and power lines.
Considering ease of maintenance and safety of operation, keep away from high voltage
devices and power lines, or, if this is impossible, separate the system from these other
devices, for example by an iron plate.
Do not mount a terminal block unit horizontally, since this obstructs ventilation.
To increase the mouting stability, fix the DIN
rail in place with screws approximately in the
center of the unit to which it is attached.
(If the terminal block is mounted flush, the
interval becomes about 240 mm.)
