Cable requirements
NOTICE:
Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep
the cable ends dry at all times.
• The cables must be in good condition, not have any sharp bends, and not be pinched.
• The cables must not be damaged and must not have indentations or be embossed
(with markings, etc.) at the cable entry.
• The cable entry seal sleeve and washers must conform to the outer diameter of the
cable.
• The minimum bending radius must not be below the acceptable value.
• If a cable is used again, then a short piece must be peeled off. Make sure that the
cable entry seal sleeve does not close around the cable at the same point again. If the
outer sheath of the cable is damaged, then replace the cable.
• The voltage drop in long cables must be considered. The voltage rated voltage of the
drive unit is the voltage that is measured at the cable connection point in the unit.
• The cables must be long enough for maintenance work.
• For SUBCAB
®
cables, the twisted pair copper foil must be trimmed.
• All unused conductors must be insulated.
• The cables must be run so that they cannot be sucked into the unit.
• The cables must comply with the local regulations.
• A screened SUBCAB
®
cable must be used between the pump and the gateway.
