Electrical installation of THM20E
5.2.1
Equipotential bonding
You must establish local equipotential bonding between the individual mobile electrical
units to prevent excessive contact voltage in the event of a fault.
Install equipotential bonding as follows:
• Connect the THM20E pick-up and all additional units with the reference potential of
the mobile unit in line with high-frequency guidelines. Establish a wide-area, metallic
contact between the unit housing and the unpainted body of the mobile unit.
• Between the THM20E pick-up and the metallic mounting plate (vehicle support
frame), you must establish low-impedance equipotential bonding via a screw con-
nection with a toothed washer on one side at a retaining screw of the THM20E pick-
up.
WARNING
Faulty installation.
Severe or fatal injuries.
• It is essential to comply with the safety notes in chapter 2 during installation.
