Decommissioning; Maintenance; General; Earth Leakage Circuit Breaker (Elcb) - Ingersoll-Rand 7/26E Operation & Maintenance Manual

Options
To ensure an adequate flow of oil to the compressor at low
temperature, never allow the discharge pressure to fall below 3.5 bar.

Decommissioning

When the machine is to be permanently decommissioned or dismantled, it is important to
ensure that all hazard risks are either eliminated or notified to the recipient of the machine.
In particular:-
• Do not destroy batteries or components containing asbestos without containing
the materials safely.
• Do not dispose of any pressure vessel that is not clearly marked with its relevant
data plate information or rendered unusable by drilling, cutting etc.
• Do not allow lubricants or coolants to be released into land surfaces or drains.
• Do not dispose of a complete machine without documentation relating to
instructions for its use.

Maintenance

General

Ensure all electrical equipment is properly maintained and controlled.
Ensure all earth connections are secure and regularly maintained.

Earth Leakage Circuit Breaker (ELCB)

The earth leakage circuit breaker must be mechanically tested daily by pushing the test
button with the machine in its no load condition. The ELCB should trip to the OFF (down)
position.
The earth leakage circuit breaker should also be tested every 3 months. A proprietary test
meter should be used to induce live to earth preset flow at each socket outlet. This current
flow will produce the required earth fault check. The test should be conducted in
accordance with appropriate national standards.

Instruments and Controls

A Voltmeter is provided to indicate the output voltage.
Miniature circuit breakers provide over-current protection. In the event of excess current
the appropriate circuit breaker will trip to the OFF position
NOTE: The current trip rating is quoted at a nominal 40° C ambient
temperature.
