Each CMC uses an auto-ranging 85 to 264 VAC power supply, 47 to 63 Hz, 330 Watts, 4.5 Amps (100-120 VA C) or 2.3 Amps (200 to 240 VAC), at 500 VoltAmps (VA). The AC power source can be 1 phase of 120 VAC with neutral (100 V AC fo r Japa n) with 15 Amp ci rcuit b reaker, or 1 p hase of 220 or 240 VAC (200 VAC for Japan) with 10 Amp circuit breaker. The AC cord uses a NEMA 5-15P plug or an IEC 320 plug.

Before powering up the system, check the AC power in the equipment room using a KS-20599 digital voltmeter (DVM) (or equivalent).

1. Measure the AC voltage between the hot and neutral side of the receptacle.

2. Depending on the AC power source, verify that the meter reads 90 to 132 VAC or 180 to 264 VAC. If not, have a qual ified electrician correc t the problem.

3. Measure the voltage between the neutral and ground side of the receptacle.

Uninterruptible Power Supply

An optional UPS (Uninterruptible Power Supply) may b e used for power holdov er. The type of UPS depends on the holdov er requirements. Hold ov er times vary from less than 10 minutes to up to 8 hours. The UP S must provide surge protection for all connected c abinets.

1. Connec t the UPS to an electrical outlet capable of handling the po wer requirements of all cabinets:

a. For 100 VAC, multiply 4.5 Amps times the number of cabinets. b . For 120 VAC, multiply 3.8 Amps times the number of cabinets. c . For 200 VAC, multip ly 2.3 Amps times the number of cabinets. d . For 220-240 VAC, multiply 2.0 Amps times the number of ca binets.

2. Be sure that Cabinet A (control carrier) is connected to an “unswitched” or

“al ways on” electric al outlet on the UPS.

Install Coupled Bonding Conductor

The Coupled Bonding Conductor (CBC) provides for mutual inductance coupling between the CBC and the telephone cables that are exposed to lightning. The conductor can be a 10 AWG (#25) (6 mm cables, a metal cable shield around the exp osed cables, or 6 spare pairs from the expos ed cable.

In a high rise building, connect the CBC to an approved building ground on each floor. To provide the coupled bond i ng p ro tection:

1. Connec t 1 end of the c onductor to a telephone c able building ent rance p rotector ground that is connected to an approved ground.

2. Route the rest of the conductor next to the exp os ed telephone cables being protected until they reach the cross-connect nearest to the telep hone s ystem .

3. Position the non-exposed telephone c ables at least 12 inc h es (30.5 cm) away from exposed telephone cables whenever possible.

4. Terminate the other end to the single-p o int ground block provided for the telep hone s ystem .
