Protect the supply voltage line for the relay box and
the control unit with the same fuse (see chapter "Spec-

1 ON indicator for supply voltage
2 Cable entries with strain relief
3 Connecting cable for control voltage
4 Power cable for supply voltage
f Set the cable grommets with strain relief into the casing.
f Route all connecting cables through the cable grommets
with strain relief. For this, knock out the knock-outs pro-
vided in the casing.
f Use the connecting cable supplied for the control voltage
from the control unit and the power cable for the supply
voltage to the relay box.
