c.Reattach or replace the faceplate as follows (see the illustration at right):

i.Making sure that both the MLC and the faceplate are upright, hold the MLC with its circuit board against the back of the faceplate, aligning the two tabs on each side of the MLC with the two slots on each side of the faceplate.

ii.Each tab has a ridge that must snap into a slot on the side of the MLC. Press the MLC into the faceplate until the ridges on all four tabs snap into place.

3.Attach the metal mounting bracket to the junction box.

a.Place the metal bracket on the electrical box, aligning the slotted holes in

the bracket with the round holes on the box.

Electrical

NOTE: To keep the MLC securely in place and prevent it from being Junction Box

easily pulled from its mounting, ensure that the side of the

bracket with the word “Front” engraved on it faces out

(away from the electrical box). If you want to be able to

remove the MLC easily from its mounting, attach the bracket with “Front” facing inward, toward the junction box.

b.Insert two of the included screws in the slots at the top and bottom of the

bracket as shown at right.

c. Tighten the screws to secure the bracket to the mounting surface. Metal Bracket

(5 mm) Max.

4.Connect the cables to the MLC rear panel ports.

Attach the cables and IR emitters to the rear panel of the MLC and to the display device or switcher as required.

Supply

in the example at right) to this port. The relay ports are normally open and rated for 24 VDC, 1 A).

NOTE: If you use both relay ports,

connect the ground wires

of both devices to common pin 3.
