cover.
To open an Explosion-Proof moisture.IQ unit, remove all 24 bolts from around the periphery of the enclosure
cover. Do not open an Explosion-Proof moisture.IQ unit that is energized.
To facilitate wiring, Weatherproof and Explosion-Proof moisture.IQ units are equipped with a hinging Chassis
that can be swung out and rested on a rod support. During normal use, the Chassis is fixed in place by a latch
mechanism located at the center of the mounting panel.
To release the Chassis from its locked position, the latch pin at the center of the mounting panel is pushed
upwards (in the direction indicated by the surrounding label). To lock the Chassis in place, the Chassis is
pushed down towards the mounting panel until the latch engages. In order to safely move the Chassis after
cables are installed, service loops for the Weatherproof units shall be at least 20 inches. Service loops for the
Explosion-Proof units shall be at least 18 inches
