WARNING
Laying of cables
Explosion hazard
Cable for use in hazardous areas must satisfy the requirements for having a proof voltage of
at least 500 V AC applied between the conductor/ground, conductor/shield and shield/ground.
Connect the devices that are operated in hazardous areas as per the stipulations applicable
in the country of operation.
WARNING
Field wiring installation
Ensure that the national requirements of the country in which the devices are installed are
met.
