Electrics
The specifications in the "Electrical" section must be imple-
mented by a company which specializes in electrical installations.
The IEC conditions apply worldwide, the NEC conditions apply
only to Canada and the USA.

The central connection point is on the electrical cabinet and is
shown on the installation plan with the illustrated symbol.
Connected loads
Notes
■
Impermissible voltage fluctuations endanger the faultless
operation of the machines and reduce their performance. A
voltage stabilizer is necessary.
■
The tolerance range applies to brief fluctuations. Measures
to stabilize the mains must be taken in the event of continu-
ally non-permitted fluctuations. These measures must be
coordinated with the energy supplier.

The tolerance of the line must be determined if the nominal voltage is
380 V or 415 V at 50 Hz. No isolating transformer is required if the
tolerance is between 360 V and 440 V.

Specification complies with the American National Standard (ANSI),
C84.1 table 1, "Voltage range A".
