Opening/Closing the Enclosure

The enclosure opens/closes differently depending upon whether you have the fiberglass enclosure
or the aluminum enclosure.
DANGER
EXPLOSION HAZARD: Never remove end cap(s) in a hazardous location. Removing end cap(s) in a
hazardous location could result in an explosion.

Installation
Once you have installed the unit, run a ground wire between the ground stud on the
bottom of the battery compartment and a known good earth ground. You route the
ground wire through one of the conduit fittings.
Use stranded copper wire to earth ground and keep the length as short as possible.
Clamp or braze the ground wire to the ground bed conductor (typically a stranded
copper AWG 0000 cable installed vertically or horizontally).
Using a high-wattage soldering iron, tin the wire ends with solder before you insert
them into the chassis ground lug.
Run the ground wire so that any routing bend in the cable has a minimum radius of
30.48 cm (12 inches) below ground and 20.32 cm (8 inches) above ground.
Fiberglass Enclosure
The enclosure includes two fasteners at the top and bottom of the door. To open the door,
lift the clasp to loosen the latch and pull it free of the post, then repeat for the other fastener
and open the door. To fasten the door, place the latch on the post and press down the clasp;
repeat for the other fastener.
