5 Electrical connection
E210 and E220 clutches have to be supplied with direct
current and are factory fitted with 500 mm long wires.
The polarity does not affect operation.
5.1 Important recommendations
All works on the electrical connections have to
be made with power off.
Ensure compliance with the nominal supply
vol tage (inadequate supply causes a reduction
in the starting distance and transmissible
torque).
The connecting wires should be of sufficient diameter
to prevent voltage drops between the source and
equipment supplied.
Tolerance in the supply voltage to the clutch terminals
+5% / -10% (NF C 79-300).
5.2 Supply
For controlling these clutches, we advise the use of
Warner Electric’ supply units.
Sizes 400 to 1600:
CBC 400-24, CBC 450-24
CBC 500-24, CBC 550-24
CBC 140-5
Sizes 3200 to 12800:
CBC 140-5
Warner Electric supply units provide protection for
coils and circuits. Where a clutch is used without our
supply units, with switching on the DC, it is essential
for the coil to be protected against surges by a varistor
fitted in parallel.
