Installing & Removing Cover
(Refer to Diagram 1 and 2 below)
The cover goes from open to full closed with a turn of about 25 degrees.
Removing the Cover
I. Loosen cover lock screw to where the bottom of the screw head is
flush with top of the cover locking tab. This is the non-locking positon
and the way it is shipped from the factory.
II. Remove the cover by turning it approximately 25 degrees
counterclockwise until it hits the stop and lift the cover off.
Replacing the Cover
I. The cover O'Ring must be in place on the housing body.
II. Place the cover on the housing with the cover locking tab 25 degrees
counterclockwise from the hole between the conduit entries (see
diagram 1). The cover will fit properly on the housing only in this
position.
III. Twist the cover 25 degrees clockwise until the cover locking screw is
directly over the hole between the conduit entries (see diagram 2).
IV. To insure the IP67 enclosure rating the cover must be completely
closed and the O'Ring sealed to keep out water. This is acheived
when the cover is closed and locking screw can be easily screwed in
until the top of the screw head is flush with the top of the cover
locking tab. Check the cover O'Ring to make sure it is in place and
not buckled.
