Wait Indicator
Instructions for mounting, replacing Helios signal heads, pedestrian signalling and demand
equipment and mounting items such as the Solar Cell can be found in the Helios Handbook
667/HB/30000/000.
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 4.1 for details), using the
six-way dropper cable.
PDU and Wait Indicator Earthing Requirements
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.
