Maintenance

In order to verify and ensure explosion-proof integrity, perform regular 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.

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.

Note: 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.

5. Reinstall the amplifier into the enclosure.

6. Re-bolt the cover using the appropriate torque specification. Refer to the Mounting section.

7. Restore power to the unit.
