Danger!
Danger to life from electric shock through degree of protection violation
Failing to ensure the degree of protection for the enclosure according to EN 60529 can result in
severe or lethal electric shock.
Ensure that the enclosure meets the required degree of protection during mounting and
installation activities:
- All seals must be undamaged and correctly fitted
- All screws of the housing/housing cover must be tightened with the appropriate torque
- Only cables of the appropriate size must be used in the cable glands
- All cable glands must be tightened with the appropriate torque
- All unused cable glands must be sealed or plugged with corresponding stopping plugs
Danger!
Explosion hazard from premature powering
Powering parts of the system during installation or maintenance leads to added currents. This
very likely results in a current flashover generating sparks. The sparks can ignite the
surrounding potentially explosive atmosphere.
Prior to installation and maintenance activities, ensure that the device is disconnected from the
power supply. Activate the power supply only after all the circuits required for operation have
been fully assembled and connected
