Connection to the Wait Indicator is via the standard housing aperture on the rear. The signal and power
cable will be derived from the Pole Top Board (reference section
for
details), using the six-way dropper cable.
Important:
The PDU and Wait Indicator require a separate Earth wire to be fed from the Pole Top
Earth Terminal or other Pole Earth points (sometimes derived from the CET gland on the
armoured cable termination) and connected to the earth terminal on the PDU or Wait Indicator
equipment.
