Maintenance and servicing

• Select maintenance cycles so that problems can be recognized in good time. Check the
following:
– The device for visible damage
– That the permitted temperatures are not exceeded
– That the cables are securely connected,
– Damage to cable and wiring entries
– Enclosure gaskets for cracks and damage
– Bonding of seal on the enclosure cover and at the bonding positions
– Surface of seal for damage
• If the seal is damaged, replace the complete cover if necessary.
• If there is damage to the enclosure, there is a risk that the degree of protection is no longer
valid. In some cases, this might necessitate replacement of the enclosure.
• If there is damage to cable and wiring entries, only replacement with original parts is
permitted.
• Check regularly, once a year, that the cable and line entries are securely in place and properly
sealed. Check the tightening torques.
If necessary, re-tighten the glands to the torques specified by the manufacturer. For
information on the torques, refer to the respective manufacturer documentation.
• Functional checks must be carried out in accordance with the EN 60079-17 guidelines.
