fittings in all conduit entries within 18 inches (46cm) of enclosure per the
National Electrical Code requirements.
To avoid risk of explosion, hazardous location information specifying
Class and Group listing of each device is marked on the nameplate of
each enclosure. Class and Group list for and device penetrating the
enclosure must be suitable for the classification of location in which the

4. Ensure the operator is in the OFF position and then remove the cover
bolts while securing cover. Carefully open the cover fully to prevent
damage to the machined joint flame path and cover gasket.
To avoid the risk of explosion, hammers or prying tools must
not be allowed to damage the flat machined joint surfaces or cover
gasket. Do not handle covers roughly or place them on surfaces that
might damage or scratch the flat machined joint surfaces.
To avoid the risk of explosion, do not use cover bolts as a means to
lift the enclosure. Excessive force on the partially retracted cover bolts
may damage the bolt. Use appropriate lifting method for safety.
5. Pull wires into enclosure, making sure they are long enough to make
the required electrical connections. Install the proper wire clamps or
other approved devices to hold the wires securely in place. Install the
ground, line and load wires. Tighten the wire binding screws to torque
