When carrying out any work on the machine, observe the general safety instructions
(Page 13) and the specifications contained in EN 50110‑1 regarding safe operation of electrical
equipment.
6.1 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
6.2 Bringing in and routing the cables
1. The screw-mounted entry plate is not normally supplied with holes. Make sure the type,
number, and size of the screw connections are appropriate to the specific cabling
requirements.
2. Only use guide elements that meet the following requirements:
– Guide elements must be adapted to suit the type and diameter of the cables.
– Guide elements must guarantee IP55 degree of protection. The same applies to
insertion points, where sealing rings and adhesive should be used.
– Guide elements must be appropriate to cable installation conditions. For example, use
cable grips where cables are not securely installed.
3. Avoid chafing the cable insulation. Route the connecting cables and, in particular, the
protective conductors in the terminal box so that they do not touch the machine and excess
length remains.
4. Close unused cable entries with suitable seal inserts. Please ensure the following:
– The seals are made of resistant, approved material.
– The degree of protection is guaranteed. Use sealing rings or adhesive, if necessary
– Only open the cable entries with a tool.
