2. Safety advice
1. Please read this advice carefully.
2. Keep this operations manual for use near the machine.
3. This is an electral device driven with high voltage, please respect
the usual VDE- and safety regulations.
Mains voltage and every voltage greater than 42 volts is
dangerous!
4. Connect to a power source following the identification plate on
the device.
5. Avoid contamination of the interior with debris, liquids or sprays.
Risk of short-circuit, fire or electric shock !
6. Before dismantling the controller insert from the frontpanel,
remove the blocking screw (upper side of the carter, red
point), switch mains power off and prevent unintentional
restart.
Put blocking screw in place after having restored the insert!
Non-compliance with this advice can cause contact to
dangerous high voltage inside the device!
7. Don‘t place the device on hot machine surfaces or near radiation
sources of hot parts.
8. Keep the power connection cable clear of hot parts or sharp
edges.
9. Disconnect the power cable immediately, if
- it was damaged,
- liquid or parts penetrated the device,
- the device was damaged by falling down or other mechanical
impacts,
- you have the suspicion of any malfunction.

10. The operator must be thoroughly instructed by a qualified
person for the work to be carried out.
11. Intervention at the device must only be carried out by qualified
staff members.
For repair, the device should be send back to our factory.
Attempted self-repair causes immediate termination of the
warranty period !
If spare parts are required, only parts recommended
by the supplier must be used. The use of other parts may
cause damage and/or hazard for operation personnel.
12. Please respect further recommandations and warnings
described in this operations manual.

4. Installation and wiring:
4.1 Installation:
The installation site must provide easy access for the operator
without hazard. Sufficient mechanical stability must be
guaranteed, also secure the device from slipping on the
installation surface.
Protect from heat, radiation and allow free air circulation.
Protect power cable from heat and mechanical stress.
Do not place the device on hot surfaces.
4.2 Connection of the power supply:
This device must only be operated at the voltage indicated on
the name plate. Please check for a sufficient fuse protection of
the power outlet foreseen for the device.
Protective earth conductor must be provided
4.3 Connection of heater and thermocouples:
Please compare the connecting diagram on the temperature
controller (backside, near the outlet) with the diagram of the
mould. Inappropriate connection can destroy controller, heater
and TC!
Available mould connecting cables contain heater–and FeCu-Ni
compensation wires for TC. Never use compensation wires to
connect a heater.
