Shield the free cable end to
prevent short circuits
Connecting of heaters 1800 t and 2400 t
With the heaters
1800 t
and
2400 t
the operating switch turns on 8V voltage, which
runs the
4430
unit, but the voltage reading on the display is incorrect (8V). It is ad-
visable to take the power for these units directly from the accumulator via a sepa-
rate fuse, in which case the reading on the display will be correct.
The power cable must have
at least a 1 A fuse
