WARNING
Overheating of power cables when permissible cross-sections are fallen below
Excessively thin power cables can result in overheating. This can result in severe injury or death
due to re and smoke.
• Only use power cables with suciently large cross-sections. Take into account the routing
type, ambient temperature and cable length.
• If smaller cross-sections are selected, you must ensure the appropriate level of conductor
protection in another way, e.g. by suitably setting closed-loop control parameters.
