6.1 Connected parts can become loose
Material damage as a result of connection parts coming loose
If you use fixing elements made from the wrong material or apply the wrong tightening
torque, this could impair current transfer or cause connecting parts to become loose. This
could result in material damage to the machine or even in total failure, which could in turn
lead indirectly to material damage to the system.
● Tighten the screwed connections to the specified tightening torques.
● Observe any specifications regarding the materials from which fixing elements must be
made.
● When performing servicing, check the fastenings.
6.2 Connecting the machine
6.2.1 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.
