INSTALLATION REGULATIONS
The module has been designed for vertical installation on a DIN 46277 rail.
For optimal operation and long life, adequate ventilation must be provided.
Avoid positioning ducting or other objects that obstruct the ventilation
slots. Avoid mounting modules over heat-generating equipment. Installation in
the bottom part of the electrical panel is recommended.
ATTENTION
These are open-type devices and intended for installation in an end enclosure
/ panel offering mechanical pro-tection and protection against spread of fire.
ELECTRICAL CONNECTIONS
CAUTION
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc…).
