4. Loosen the mounting bracket screws enough to allow for the mounting
collar and panel thickness. Place each mounting bracket into the
mounting slots (head of the screw facing the back of the controller).
Push each bracket backward then down to secure it to the control
case. To guarantee a proper NEMA 4X seal, Series 996 and 998
units (vertical) must have the mounting brackets located on either
side of the unit. When installing Series 997 and 999 units (horizon-
tal) the brackets must be on the top and bottom of the unit.
5. Make sure the case is seated properly. Tighten the installation screws
firmly against the mounting collar to secure the unit. To ensure a
NEMA 4X seal, there should be no space between the bezel and
panel. Overtightening the screws will distort the case and make it diffi-
cult to remove or replace the controller.
6. Insert the controller chassis into its case and press the bezel until all
four tabs snap. Make sure the inside gasket is seated properly and not
twisted.
7. To release the mounting brackets, loosen the mounting bracket screws
and push the brackets forward, then pull it up and out.
ç
CAUTION:
Follow the installa-
tion procedure
exactly to guaran-
tee a proper NEMA
4X seal. Make sure
the gasket between
the panel and the
rim of the case is
not twisted and is
seated properly.
Failure to do so
could result in dam-
age to equipment.
