Note: When using wire end ferrules with isolating collar, make sure you do not
introduce the insulation of the wire end ferrule into the clamping area of the
terminal.

3.8 Power Supply Line
Select the cross-section of the power supply line such that line losses are as low as possible.
• However, observe the following points:
o Due to the construction, the recommended feed line for all cross-sections is a fine-
strand line.
o The cable fitting of the standard connector housing supplied allows a 5 x 6 mm²
cable to be connected. The maximum outside diameter of the power supply line
may be 18 mm (e.g. Lapptherm 145, 5 x 6 mm²).
o Optionally, you can also order a larger connector housing allowing connection of a
5 x 10 mm² power supply line.
The table below shows the maximum line lengths in relation to the conductor cross-section
with a voltage drop of <= 1%.
Line cross section 4.0 mm² 6.0 mm² 10.0 mm²
Max. line length 20 m 30 m 50 m
Note: To ensure protection class IP65, the connectors and power supply
lines must be matching each other and all unused connections must
be provided with blanking plugs.
