Installation
5.6 Connect to the energy supply network
DANGER Danger to life if the electrical installation has not been carried out profession-
ally!
Installation that has not been carried out professionally or properly can cause serious
injuries or death. The whole electrical system can be destructed.
Ø
The electrical installation must only be carried out by a qualified electrician ob-
serving EN 60204.
Ø
The main switch has to be provided by the user.
CAUTION
Property damage due to wrong energy supply!
Wrong operating voltages, frequencies or currents can cause loss of power or dam-
ages to the machine.
Ø The conditions at the installation location must comply with the details on the mo-
tor data plate.
Ø
Permissible tolerances:
• ± 5 % voltage deviation
• ± 2 % frequency deviation
5.6.1 Connection of motor
a) The electrical motor data can be found on the data plate (Fig. 2/N, 3/N) or the motor data plate (Fig. 2/
P1). The motors comply with DIN EN 60034 and are designed in protection class IP 55 and insulation
class F. The appropriate connection diagram is located in the terminal box of the motor (not existing for
the version with plug connection). Compare the motor data with the data of the existing mains network
(current type, voltage, network frequency, permitted current value).
b) Connect motor via motor protection circuit breaker (For strain relief provide for a screwed cable con-
nection to connect the connecting cable).
We recommend using motor protection circuit breakers with delayed switch off, depending on a possible
excess current. Temporary excess current can occur when the machine is started under cold conditions.

5.6.3 Connect fan / circulation pump (circulating cooling)
a) Connect the circulation pump (Fig. 3/W1) (use supplied connector) and get it run at the highest level
(level III).
Voltage: 1~, 230 V (50 Hz / 60 Hz)

See connection diagram of circulation pump (product documentation)
b) Connect fan (Fig. 3/V
A
) to the terminal box (Fig. 3/V
