4. Repeat procedure (steps 1 through 3) to attach the remaining ear to the

opposite side.

Bussing Strip Installation

The MC2W is supplied with a brass bussing strip to facilitate commoning (linking)

of multiple terminal block connections. The bussing strip is constructed with four

terminal block positions and may be trimmed to size for various applications or

different devices. One strip is supplied for the 8-position terminal block (four

relays).

1. To utilize the bussing strip, determine the number of relays to be

commoned for the equipment being installed. If less than four, the strip can

be trimmed to size with a pair of scissors or wire snips.

2. Loosen the terminal block screws and insert the first leg of the bussing strip

into the first common position of the terminal block. The strip engages the

other common positions automatically.

3. Remove approximately 1/8” of the jacket from the common wire and insert

the conductor into one of the terminal block common positions. Tighten the

terminal block screws to lock the wire and bussing strip into place. Insulate

the strip by folding a piece of ¾” wide vinyl electrical tape (such as Scotch

33+) over the spine and as much of the individual legs as possible. Excess

tape at each end of the strip should be pressed closed, then trimmed to

within approximately 1/16” of the end of the strip.

4. When wiring the remaining conductors, remove approximately 1/8” of the

jacket and insert the wires into the proper terminal block positions. To

prevent the possibility of electrical shorts, it is essential that these

conductors do not touch any uninsulated portion of the bussing strip.

5. Securing a tie wrap around the bussing strip is a useful way to provide

strain relief for the wires connected to the terminal block.

Stacking

Four “feet” are provided with the MC2W so that if the unit is not rack mounted, the

rubber feet can provide stability when the unit is placed on a flat surface or stacked.

These feet should be attached prior to the hookup procedure.

Hardware Hookup

Make the necessary connections as called out in the illustration on the following

page. Refer to “Network Wiring” on page 8 before attaching the 4-position terminal

block connector. Apply power after all connections have been made.

When making connections to the MC2W, consider the following:

• Use Crestron power supplies for Crestron equipment.

• The included cable cannot be extended.
