MAINTENANCE

At regular intervals, depending upon the particular location of the MTL GECMA RT
COM module, the general state of the unit should be assessed for both its electrical
and mechanical condition.
The following item checks should be considered for inspection.
1. Check for any signs of wear, tampering, or impact damage to the RT COM
module. The equipment must be taken out of use immediately if the damage
is judged to be affecting its Ex protection.
2. Check all ground (earth) connections for integrity and condition. Check for
any signs of corrosion at terminals, and that all screw connections are
adequately tightened.
3. Check power connection from the MTL GECMA WS PSU module.
If there are signs of wear or cable damage the equipment must be taken
out of service immediately and not restored to use until any damaged
cables have been replaced.
4. Check the tightness of all mechanical fastenings.
5. Check for the presence or build-up of dust, dirt or contaminants on the module
and its surrounding equipment and deal with any accumulations appropriately.
6. Check for any other maintenance issues that may be dictated by site rules.
7. Avoid using aggressive acids or bases when cleaning.
