Changing any key parameters such as supply voltage or cable length will result in the output power differing from the design, which may require recalculation of the entire system and a change in the heating cable type.

Crossing heating cable strands with constant power is not permitted. The minimum permissible gap between heating cable strands is 20 mm.
