6.6. External Connections
Cable access is normally from a cable duct beneath the cabinet.
However, suitable openings are available for fitting in the roof of the
cabinet, where cables have to enter from above. This requires the
replacement of the standard roof plates by plates fitted with dust-tight
cable glands.
6.6.1. Auxiliary Supply
The auxiliary supply connections is over the circuit breaker for the
power supply, type B9AS. From the circuit breaker a cable goes to
supply connections at the top of the left-hand side plate of the power
amplifier rack P7LA.
Faston plugs on the cables connected to the rack P7LA must be
covered with an isolation sleeve. Unused faston connectors have to be
covered.

The ETL600 can be equipped with the unit B5LA for 48 V DC supply or
with the unit B5LC for 115/230 V, 50/60 Hz AC supply.
The connections will be accordingly, either to the DC or the AC
terminals:
+ positive battery pole DC supply
- negative battery pole DC supply

DANGER
Make sure that the power supply B5LC is
programmed to the correct voltage of 230 VAC or
115 VAC as described in 1KHL015788 before
connecting the equipment to the power source.
6.6.2. Coaxial Cable
BNC coaxial connectors are provided on the rear of the power
amplifier rack P7LA for the RF signals. However when the ETL600 is
mounted in a cabinet, the RF signals are internally wired to a plate
mounted inside the cabinet. The external RF coaxial cable has to be
connected to this plate. Refer to the photographs in section 6.5.
