CAUTION:

If you do not have a thermal circuit breaker or fuse in your power circuit, e.g. fitted to the DC distribution panel, you MUST fit an in-line breaker or fuse to the positive (red) lead of the power cable.

The open array scanner has a power switch fitted to the pedestal. This switch can normally be left ON. However, if the scanner is being serviced or if any personnel are in the vicinity of the open array, the switch should be set to OFF.

Scanner connection

The inter-unit cable is connected to the scanner as described in Sections 2.1 and 2.2. If you are using an inter-unit extension cable, connect this to the display unit, and connect the supplied cable to the extension cable. The scanner connector pins are shown in the following diagram, together with the connections and core colors.

CAUTION:

The display connector on the inter-unit cable is a moulded plug that cannot be replaced. DO NOT remove this moulded plug.
