Installation
6 --- 32
Shut---off valve (2) to be installed by the user in the connection line.
Make the compressed air connection with a flexible hose (1) or an axial compensa-
tor (1).
6.4 Electrical Connection
Have the electrical connection made only by a qualified and authorised electrician.
Carry out protection measures as stipulated in relevant regulations (IEC 364 or DIN
VDE 0100, for example) and in national accident prevention regulations (BGV A2 in Ger-
many). Also observe the regulations of the local power utility company.
Use wire conductor dimensions and fuse ratings in accordance with local regulations (DIN
VDE 0100 parts 430 and 523 in Germany, for example).
Check the reaction time of overload protection devices (e.g. DIN VDE 0100 part 413).
Guide values are given in chapter 2.9.
The user must provide the machine with a lockable mains---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.
Before Initial Start---up
The control transformer in the control cabinet has connections for various supply volt-
ages. Check that the correct connections are made for the supply voltage provided for
the machine. If necessary, re---connect the transformer to match the supply voltage
using the
5% taps. (see Fig. 11 and chapter 13.1.4)
