Maintenance
In order to verify and ensure explosion-proof integrity, perform regular preventive maintenance and
inspection checks on the GAI-Tronics explosion-proof enclosure. The GAI-Tronics Field Service
Department can formulate a service contract to suit specific preventive maintenance needs.
CAUTION
Remove power from the enclosure before performing any maintenance.
Use the following procedures to ensure reliable operation of your equipment:
1.
Remove power from the enclosure.
2.
Unbolt the cover, and remove the amplifier from the enclosure.
3.
Visually check the interior of the enclosure for signs of contamination. Contamination inside the
enclosure could mean that the conduit seals or cable gland seals have been compromised.
4.
Ensure the gasket and hardware are in place and in good condition. Restore power to the unit.
In certain circumstances, it may be necessary to re-terminate wire connections to some or all of the
enclosures in a system. When this is done, strip the wires back to clean copper, reconnect to each
terminal.
