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.
