(1) For 200 - 250 V range only
Minimum for safe value means the smallest fuse that can be used with
respect to power consumption and start up current.
Maximum allowed must not be exceeded due to the dimensions of the
internal wiring and components.
AC Power Cables
There are four external power cables for the radio cabinet, one for each
Power Supply Unit. They are connected to the ACCU main switch with
screw terminals.
The conductor area can be 1.5 – 2.5 mm

and the cable diameter can be
8.5 – 12.5 mm.
