CONNECTING THE PANEL
Connect AVAC’s internal wiring immediately prior to commissioning and after you have refit-
ted the lid, chassis mounting plate, lid/base connecting cable and earth straps by reversing the
process described on page 10.
Before connecting any wiring to the PCBs, we recommend you check all third-party equipment
(loudspeakers, emergency microphone, paging panels, background music sources, etc) to ensure
they are correctly fitted and that cable integrity is verified throughout the installation.
It is essential that the wiring and loudspeakers are tested with a Loadmaster or LCR meter to
ensure that the total load connected to each of the loudspeaker circuits is not greater than
60 watts (not less than 167 Ohms) at 1 kHz. See page 15 for important information on the
loading of loudspeaker circuits.
DO NOT use a high voltage insulation tester with any electr
onic devices connected.
