➤ Collect condensate in a suitable container and dispose of in accordance with environmental
regulations.
Further information The dimensional drawing in chapter 13.3 gives the size and position of the condensate drainage
connection ports.
6.5 Making the Power Supply Connection
This is a Tri-Voltage machine.
The machine can be set up to one of the following supply voltages:
■ 208V
■ 230V
■ 460V
Precondition The power supply disconnecting device is switched off.
The disconnecting device is locked in the off position.
A check has been made to ensure no voltage is present.
1. Have the electrical connections carried out by authorized personnel only.
2. Carry out protection measures as stipulated in relevant regulations (IEC 364 or example) and in
national accident prevention regulations. In addition, the regulations of the local electricity supplier
must be observed.
3. In case of a fault, check the disconnecting time of the supply disconnecting device.
4. Use supply conductors and fuses in accordance with local regulations.
5. The user must provide the machine with a lockable supply disconnecting device.
This could be, for example, a switch-disconnector with fuses. If a circuit breaker is used it must
be suitable for the motor starting characteristics.
6. Check that the correct taps on the control voltage transformer are connected according to the
supply voltage.
If this is not correct, change the connection to suit the power supply voltage.
DANGER
Danger of fatal injury from electric shock!
➤ Switch off and lock out the supply disconnecting device and check that no voltage is present.
7. If necessary: Set up the machine for the correct power supply voltage as described in chap‐
ter 6.5.1.
8. Connect the power supply.
Further information The electrical diagram 13.4 contains further specifications for electrical connection.
