Step 5:

Make the power and data connections on the backplane.

a: Install the dimmer output ribbon cables. Open the black retaining tabs for each

connector until they are at a 45° angle to the backplane. Press the connectors

into their respective locations until the tabs lock in place at a 90° angle to the

backplane. Make sure the proper side is facing up on each connector and

that each connector is fully seated.

b: Install the power harness (Look at the pin shapes for proper orientation. It will

only fit one way.)

c: Install the DMX connections. (The wires travel out of the top on both styles of

connectors.)

d: Install the 3-pin beacon connector (The wires travel out of the bottom of the

CEM3.)

e: Connect the CAT5 Ethernet cable to the RJ-45 connector on the CEM3

backplane. (Not shown in the drawing below for clarity.).

Step 6:

Push the backplane completely into place in the rack. Be careful not to disrupt

the power and data connections you just made. Make sure none of the wiring

becomes stressed or pinched.

Step 7:

Insert the backplane tabs in the side of the rack.

Step 8:

With the tabs fully inserted in the

sides of the rack, pull the

backplane towards the front of

the rack to line up the screw

holes in the upper side corners

to line up.

Step 9:

Install one screw with a sleeve in

each side upper-corner of the

backplane.

N o t e :

You cannot use the old screws without the additional shoulder-sleeve as they will

block the CEM3 from being fully inserted.
