Planning and Installation Guidelines
The supply lines for a primary loop must be twisted with each other or held closely together in any
other way (e.g. by cable ties, heat shrinkable tubes, etc.) over the entire distance to the power
supply.
The total length of all supply lines for one pair of primary loops can be max. 8 m.
The line length required for one primary loop can be calculated as follows:
line length = circumference x number of windings + 2 x supply line length.
Due to double insulation the supply lines can also be laid open.
For higher stability the supply lines for a primary loop (twisted with each other or held closely
together in any other way) can be laid in armored plastic or steel conduits or similar materials.
