EVC standard bus cable when there are several helm
stations (HCUs) in the system. Also please refer to
the Building a network, requirements chapter.
IMPORTANT! The Y-connector must always be
connected directly to the PCU (X2) or the HCU

IMPORTANT! There must always be one key
switch to operate each engine. The key switch
shall be connected to the main helm station.
On additional helm stations start/stop panels
should be used.
Locate a dry, suitable place for the switch and make
a hole according to the drawing.
Fix the adhesive label.
The switch fits to 2 mm (0,08”) panel. If the switch
is installed in a thicker panel the switch housing can
be trimmed by up to 10 mm (0,4”), 1 mm (0,04”) bet-
