ENC1 with PS3 Installation
Installing a unit with a PS3 attached requires some planning. It is
recommended that the unit with the PS3 attached be temporarily installed
in the enclosure to determine the best location for the conduit fitting to avoid
interference with the PS3.
1. Mark the location of the conduit fitting and drill the necessary hole.
2. Apply adhesive side of panel gasket to rear enclosure opening.
DO NOT APPLY THE ADHESIVE SIDE OF THE GASKET TO THE
ACCESS PANEL.
3. Slide the panel gasket over the rear of the unit to the back of the bezel .
4. Remove the common and V+ screw terminals from the rear of the unit (save
for later use) and replace them with the hex drive stand-offs (supplied with
the PS3).
5. Assemble nut fastener and mounting screw onto both sides of the mounting
clip. The tip of the screw should not project from the hole in mounting clip.
6. Route the wire to be connected to the unit from the conduit fitting through the
mounting clip, and then through the rear of the enclosure and out the front.
7. Connect the necessary wires to the unit for the application desired.
8. Install the unit through the opening in the front of the enclosure until the
bezel flange contacts the panel mounted gasket.
9. Slide the mounting clip over the rear of the unit until the mounting clip is
against the inside of the enclosure. The mounting clip has latching features
which engage into mating features on the unit’s housing.
Note: It is necessary to hold the unit in place when
sliding the mounting clip into
position.
10. Alternately tighten each screw to ensure uniform gasket pressure. Visually
inspect the front panel gasket. The gasket should be compressed to about 75
to 80% of its original thickness (Recommended torque is 28 to 36 in-oz.). If
not, gradually turn mounting screws to further compress the gasket.
11. If the gasket is not adequately compressed, and the mounting screws can no
longer be turned, loosen the mounting screws and check that the mounting
clip is latched as close as possible to the inside of enclosure. Repeat the
procedure for tightening the screws.
12. Connect AC power to the terminal block of the PS3.
13. Mount the PS3 and optional sensor wires needed, to the stand-offs
using the screw terminals from the unit with the supplied square washers.
14. After all electrical connections have been made, attach the rear access panel
to the enclosure with the eight screws provided.
15. Alternately tighten each screw to ensure uniform gasket pressure. Visually
inspect the sponge rubber gasket. The gasket should be compressed to about
75 to 80% of its original thickness.
ENC1 INSTALLATION
It is recommended to wire the unit before mounting it in the enclosure to
ensure good electrical connections. The following steps outline the most
common sequence for installing a unit without an PS3 attached.
1. Determine the location of the conduit fitting and drill the necessary hole.
2. Apply adhesive side of panel gasket to rear enclosure opening.
DO NOT APPLY THE ADHESIVE SIDE OF THE GASKET TO THE
ACCESS PANEL.
3. Slide the panel gasket over the rear of the unit to the back of the bezel .
4. Assemble nut fastener and mounting screw onto both sides of the mounting
clip. The tip of the screw should not project from the hole in mounting clip.
5. Route the wire to be connected to the unit from the conduit fitting through the
mounting clip, and then through the rear of the enclosure and out the front.
6. Connect the necessary wires to the unit for the application desired.
7. Install the unit through the opening in the front of the enclosure until the
bezel flange contacts the panel.
8. Slide the mounting clip over the rear of the unit until the
mounting clip is against the inside of the enclosure. The
mounting clip has latching features which engage into
mating features on the unit’s housing.
Note: It is necessary to hold the unit in place when
sliding the mounting clip into position.
9. Alternately tighten each screw to ensure uniform
gasket pressure. Visually inspect the front panel
gasket. The gasket should be compressed to about
75 to 80% of its original thickness (Recommended
torque is 28 to 36 in-oz.). If not, gradually turn
mounting screws to further compress the gasket.
10. If the gasket is not adequately compressed, and the mounting screws can
no longer be turned, loosen the mounting screws and check that the
mounting clip is latched as close as possible to
the inside of the enclosure. Repeat the
procedure for tightening the screws.
11. Attach the rear access panel to the enclosure
with the eight screws provided.
12. Alternately tighten each screw to
ensure uniform gasket pressure.
Visually inspect the sponge rubber
gasket. The gasket should be
compressed to about 75 to 80% of its
original thickness.
