Selecting cables
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
● Observe the information 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.
● 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

Terminal box
Hazardous voltage
Electric motors have high voltages. When incorrectly handled, this can result in death or
severe injury.
Switch off the machine so that it is in a no-voltage condition before you open the terminal box.
