INSTALLATION AND MAINTENANCE MANUAL

– Make sure the supply voltage is always within the limits specified in the „3. Technical specification“ table
in all circumstances. When you have long distances in the electrical installation, it may be necessary to use
bigger cables to reduce the voltage drop.
– When the machine is connected near a large capacity power supply transformer (500kVA or more, wiring length
shorter than 10m) or there is a power capacitor switch-over, a power supply improving reactor must
be installed. If you do not install this, the inverter may get damaged. Contact your sales office for more info.
WARNING!
GROUNDING: IN EVENT OF MALFUNCTION OR BREAKDOWN OR LEAKAGE CURRENT,
THE GROUNDING WILL REDUCE THE RISK OF ELECTRICAL SHOCK AND SERVE AS A PROTECTING
DEVICE, BY PROVIDING A PATH OF LEAST RESISTANCE OF ELECTRICAL CURRENT.
THEREFORE IT IS VERY IMPORTANT AND THE RESPONSIBILITY OF THE INSTALLER TO ASSURE
THE WASHER IS ADEQUATELY GROUNDED AT THE POINT OF INSTALLATION TAKING
INTO CONSIDERATIONS THE NATIONAL AND LOCAL CONDITIONS AND REQUIREMENTS.
1. Residual current device (RCD)
2. Laundry electrical switchboard
3. Supply protection device
4. Washing machine
5. Phase conductors
6. Protective conductor
7. Main switch inlet terminal switchboard
8. Neutral conductor

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 :
– Tripping current : 100mA (if locally not available/allowed use a 30mA trip current, preferably selective type
with small time delay set)
– Install max. 2 machines on each RCD (for 30mA, only 1 machine)
– 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 preformance 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).
The machine control circuits are mostly supplied by 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 the table „Technical specifications“ for the rating of the nominal current and other specifications of the supply
protection device. In this table there is specified that the 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.
