conditions and the hours of operation. The recommendations given
within IEC/EN60079-17 for recurring checks must be observed. If the
luminaire is opened for maintenance purposes or to replace the lamp,
ensure that the "nR" properties are not affected.
This could be done by testing the restricted breathing properties as
per Section 10.

8.3 LAMP REPLACEMENT

The suggested interval between lamp changes given by the lamp
manufacturer must be followed (see Section 6.7 for details).
After replacing the lamp, ensure that the "nR" properties have not
been affected. This could be done by testing the restricted breathing
properties as per Section 10, for example.
9.0 REPAIR/OVERHAUL/MODIFICATIONS
Repairs and overhaul may only be carried out with genuine Cooper
Crouse-Hinds spare parts.
Before replacing or disassembling individual parts, observe the
following:
Disconnect the power supply to the equipment before
maintenance/repair.
Make sure that there is no explosive atmosphere when opening the
equipment.
Only use original spare parts.
If the luminaire was previously in operation, wait 10 minutes before
