Requirements for the electrical connection
Work on the electrical part of the machine may only be undertaken by specialist
personnel.
The customer must guarantee the following points relating to the connection:
The correct voltage and type of current must be available
Safeguard the power supply cable according to regulations and provide it with a
power disconnection device in the fixed electrical installation.
The machine must be connected to the potential compensation system!
If an unearthed neutral (N) is used with alternating current, the power
disconnection device must have 4-poles (with alternating current 2-poles).
Conductor colors: live conductor L1 = black/1, L2 = brown/2, L3 =grey/3, neutral
conductor N = blue/4, protective earthing conductor PE = green-yellow.
Connection to be effected with the attached power supply line with plug. The
mains plug is the main switch and must be freely accessible after installation of
the machine.
CAUTION!
Current applicable standards and requirements of local utility companies are to be
adhered to with regard to protective measures and connection of the potential
compensation system.
Do not protect by fuses any additional consumers together with the machine.
All conductor fixing screws must be re-tightened before commissioning the
appliance.
The wiring diagram is behind the front panel, resp. front cladding of the appliance. The
enclosed wiring diagram must remain in the appliance.
Note to customers/
Dishwashing machines, bedpan rinsing units and systems are intended for fixed, electrical
power supply installation as well as connection to the locally available equipotential
bonding and have been equipped with a corresponding connection option.
Operators may decide at their own discretion and responsibility to implement personal
protection in locally available services in collaboration with a specialist electrician
registered at the corresponding energy supplier using the following:
AC/DC sensitive fault current protection switch with at max. 30mA EN 62423
or
Automatic shutdown of the supply in the event of loss of protective earth conductor
conductivity (EN 60204-1, Section 8.2.8.c)
7.5
Requirements for the fresh water connection
Fresh water connection must be made according to EN 1717 or according to local
regulations.
CAUTION!
The minimum flow pressure of the clean water supply upstream of the solenoid
valve must be 2.5 bar. The maximum pressure must not exceed 5 bar.
If the flow pressure is below the minimum, increase the flow pressure with a
booster pump; if the maximum pressure is exceeded, limit it with a pressure
reducer.
Suitable protective measures must be taken to ensure that no iron particles can
enter the appliance via the mains water supply. Similarly, precautions must be
taken to prevent the entry of other metal particles, for example copper turnings.
Corresponding instructions are contained in the installation drawing. Therefore
suitable measures must be taken.
A dirt trap must be fitted into the fresh water supply to protect the solenoid valve.
