Cable gland assembly and power line connection
Risk of electric shock when the connection box lid is not installed.
When you work with the power connections make sure that electricity has been disconnected and the electric device has
discharged. Measure the level of the remaining voltage before you touch the power terminals.
All electrical connections must be done according to instructions. It is essential to make sure that
all terminal connections are installed properly and the and the intended application is suitable for
the product in terms of electrical requirements/characteristics.
The high current and high voltage cable harness for AC and DC connections needs to be
terminated with cable lugs and cable glands. It is recommended to use IP67/68 rated, 360º
shielded cable glands and single core automotive rated screened cable. The cross section area of
the copper cable must be 70 mm
2
or smaller, depending on the needed maximum current.
The cable gland has three functions, it works as a stress relief, it seals the connection against water
and dirt and provides appropriate EMI shielding. Advanced cable glands could achieve high EMI
attenuation over a wide frequency range.
The cable lug and cable gland must be assembled according to instructions. For correct assembly
of the cable gland, it is recommended to use a torque key with a turnkey head and a key to adapt
the cable gland. The cable lug is connected to terminal with a M8 screw. Shielding of the power
cable must be connected to the electric device body by the cable gland. Recommendations for the
tightening torques must be followed.
