890 Installation Kit
The 890 Installation Kit is shown in the diagram attached to the bottom of
the 890CD units. It can also be fixed to the top of the unit.
The kit provides several options for earth/ground connections. It also
includes the brackets for DIN rail mounting the unit. Refer to the instructions
in the kit and use the appropriate parts.
* Permanent Earthing
The unit must be permanently earthed according to EN 50178: A cross-
section conductor of at least 10mm² is required. This can be achieved either
by using a single conductor (PE) or by laying a second conductor though
separate terminals (PE2 where provided) and electrically in parallel.
