Connection to the power supply
Electrical safety
The electric motor has been designed for one voltage only. Always check that the power
supply corresponds to the voltage on the nameplate.
Do not change the plug unless you are duly authorised to do so!
Take the DDM3 - 230 to your nearest Marcrist Distributor.
In-line protector RCD
The DDM3 – 230 features a residual current device that cuts off the unit within 15
milliseconds in the event that there is a difference (>10 mA) between the currents flowing in
and out of the unit. The user is therefore protected should any water come into contact with
any of the electronic components.
Never use the tool without the RCD provided with the tool. Always test the correct
operation of the RCD before starting work (see below).
To test the RCD unit is working correctly, proceed as follows:
• Plug in machine into the appropriate power supply (11).
• Depress the reset button on RCD (10) (Red light indicator is illuminated).
• Switch on the machine by depressing trigger (1).
• Depress the test button on RCD (10).
• The switch must break the circuit (red light indicator goes off and machine switches off).
• RCD is working correctly.
If in the test mode the switch does not break the circuit DO NOT USE.
Take the DDM3 - 230 to your nearest Marcrist Distributor to arrange inspection &
repair.
It is not permitted to make any modifications to the machine, in
particular it is not allowed to open the RCD or to repair or to replace the cable. If it
is need of inspection or repair take to your nearest Marcrist distributor.
Never use the RCD as a main switch. Always switch on the RCD under no
load condition.
If an extension cable is to be used always ensure it is of an approved type
for application and the cable is of a minimum rating for the machine. Always
operate extension cord with the cable reel fully unwound.
Use in ambient conditions.
It is not recommended to use your DDM3 - 230 machine in conditions that are extreme hot
or extreme cold. Do not use the machine in wet conditions.
