Connecting the machine

• Carefully comply with the information provided in EN / IEC 60034-1 (VDE 0530-1) regarding

operation at the limits of A and B zones, especially in respect of temperature increase and

deviation of the operating data from the rated data stamped on the rating plate. Do not

exceed these limits. Do not use machines in zone B that are marked for zone A.

• Connect up so that a permanently safe electrical connection is guaranteed (no protruding

wire ends); use the assigned cable-end fittings (e.g. cable lugs, end sleeves).

Connect up the line supply voltage and arranged the disconnecting link in accordance with

the circuit diagram provided in the terminal box.

• Select the connecting cables in accordance with DIN VDE 0100 taking into account the rated

current and the installation-specific conditions – e.g. ambient temperature, routing method

etc. - according to DIN VDE 0298 and/or EN / IEC 60204‑1.

The technical specifications stipulate the following that have to be taken into account with

respect to the motor connection:

• Direction of rotation

• The number and arrangement of the terminal boxes.

• The circuit and connection of the motor winding

6.2.1

Take the following criteria into account when selecting the connecting cables:

• Rated current

• Rated voltage

• If required, service factor

• System-dependent conditions, such as ambient temperature, routing type, cable cross-

section as defined by required length of cable, etc.

• Configuration notes

• Requirements according to IEC/EN 60204‑1

• Dimensioning for bundled cable routing, e.g. according to DIN VDE 0298 Part 4 or

IEC 60364-5-52
