The valid local regulations must be observed
For operation of the controllers in UL-approved systems:
• Use only UL-approved fuses and fuse holders:
– 500 V to 600 V in the mains input (AC)
– 700 V in DC-bus voltage (DC)
– The activation characteristic is defined by ”H” or ”K5”.
• Use only UL-approved cables.
Tip!
UL-approved fuses and fuse holders can be obtained from, e.g. Bussmann or Ferraz.
Connection of the motor cables
• The protection of the motor cables is not necessary for functional reasons.
• Refer to the data listed in the table ”Operation with mains filter”.
