Installation

Wiring Connections and

Startup (contd.)

5.Refer to Table 2-5. Install appropriate external lightning arrestors on the input power supply lines as close as possible to the CCR’s input terminal block TB3 (12).

NOTE: If optional lightning arrestors are ordered with the regulator, they are factory-installed.

NOTE: Since lightning is a phenomenon that varies in intensity and frequency with geographical locations, it is recommended that each installation evaluate the need for additional lightning protection.

6.Short-circuit the output terminals on TB1 (10) using AWG 10 (minimum) wire.

7.Refer to Table 2-4. Connect the voltage supply lines from the disconnect switch or main circuit breaker to the CCR input terminal block TB3 (11). Tighten all connections.

NOTE: Do not route the output cable in the vicinity of other wiring sensitive to EMI or RFI.

8.Energize the regulator by engaging the main circuit breaker or disconnect switch. Turn the regulator’s circuit breaker CB1 (7) to the on position, and turn rotary selector switch S1 (6) to all brightness steps. Verify current values on the panel ammeter (1) correspond to those in Table 2-8.

9.De-energize regulator by disengaging the main circuit breaker or disconnect switch. Turn the rotary switch S1 to the OFF position.

10.Connect the remote control lines, if required, to remote control terminal block TB2 (11). All CCRs use AWG 19, 300 V or larger control wire size. See Figures 3-4 and 3-5 for remote control connections.

NOTE: Tables 3-2 through 3-4 give the necessary connections for remote control. Terminal B1 (or B10) does not need to be wired. Brightness step B1 (or B10) occurs when the regulator is switched on.
