Safe Power Connection/Disconnection
To satisfy Division 2 requirements, the equipment will not create arcs or sparks in normal operation when
completely installed and powered. Installing or removing an amplifier or plugging in a live enclosure is
not normal operation and can create arcs.
CAUTION
To guarantee safety, do not insert or remove equipment from live enclosures, unless the area is
known to be non-hazardous at the time.
A better arrangement uses a separate power disconnect, performed safely in either of two ways:
1. Explosion-proof disconnect switch (can be located in the Division 2 area).
2. Ordinary disconnect switch in a non-hazardous area (outside the Division 2 area).
Either method allows the use of the switch at all times. Connect field wiring as detailed in instructions
for the same equipment mounted in non-hazardous areas.
