Residual current device (RCD)
In some countries an RCD is known as an “earth leakage trip” or “Ground Fault Circuit Interrupter” (GFCI)
or an “Appliance Leakage Current Interrupter” (ALCI) or “earth (ground) leakage current breaker”.
Specifications:
o
Tripping current: 100mA (if locally not available/allowed use a 30mA trip current, preferably selective type
with small time delay set)
o
Install max. 2 machines on each RCD (for 30mA, only 1 machine)
o
Type B. There are components inside the machine which make use of DC voltages and therefor a “type B”
RCD is necessary. For information only: Type B is better performance than type A, and type A is better than
type AC.
When locally allowed, there must always be installed an RCD. In some power network earthing systems
(IT, TN-C,…), an RCD might not be allowed (see also IEC 60364).
Some washer control circuits are supplied with a separating transformer. Therefore the RCD may not detect
faults in the control circuits (but the fuse(s) of the separating transformer will).
Supply protection device
A supply protection device basically protects the machine and wiring against overloads and short circuits.
As supply protection device, you can use either (glow-wire) fuses or (automatic) circuit breakers.
See “Technical data” for the rating of the nominal current and other specifications of the supply protection
device. Protection must be the “slow” type, for circuit breakers this means curve D.
Although not recommended, if for some reason you can not use a slow type, select the protection device
with 1 step higher nominal current rating to avoid disconnecting during start-up.
Supply cable
The supply cable is not delivered with the machine.
Specifications:
o
Conductors with copper cores
o
Stranded conductors are strongly recommended (flexible wiring) to avoid conductor breaking because
of vibration.
o
THE CROSS SECTION DEPENDS ON THE USED SUPPLY PROTECTION DEVICE.
SEE TABLE 24, FOR THE MINIMAL CROSS SECTION.
o
As short as possible, directly from the supply protection device to the washer without branching off.
o
No plug or extension cords: The machine is intended to be permanently connected to the electrical network.
Connection:
o
Insert the cable through the hole in the on the rear panel, insure a strain relief (turnbuckle) is used so that
the supply cable can not move.
o
Strip the conductor ends according figure 28.
o
The protective conductor must be longer so that when the cable is pulled out accidentally, this conductor
is disconnected the last one!
o
With stranded conductors, use “wire end tubes” with an insulated sleeve (6) for L1/U, (L2/V), (L3/W), (N)
conductors. Make sure there can not be make accidental contact, since the supply cable stays under
voltage even when the main switch is off.
o
Crimp a ring terminal (eyelet) to the protection conductor for good fixation to the PE terminal.
o
Connect the supply cable conductors to the incoming terminals (main switch (1)) marked with L1/U, (L2/V),
(L3/W), (N), and the terminal (copper screw) marked with PE, see figure 29.
o
Provide a sag in the cable, in front of the cable strain relief. This will avoid ingress of condensed water into
the machine, see figure 29.
