5.4.2 Shielding
ƒ
The effectiveness of a shielded cable is achieved by:
– Establish a good shield connection by using a large−area shielding support.
– Only use shielding braid with low shielding resistance made of tinned or
nickel−plated copper braid.
– Use braid with an overlap rate > 70 % and an overlap angle of 90 °.
– Keep unshielded cable ends as short as possible.
Make these connections with system cables or shielded:
ƒ
Motor
ƒ
HV on−board supply system
You can make these connections unshielded:
ƒ
LV on−board supply system (only PSU)
ƒ
24−V supply
ƒ
Digital signal (inputs and outputs).
– From approx. 5 m cable length or in heavily disturbed environments we
recommend the use of shielded cables.
Connection system
Prefabricated cables for the motor connection and the connection to the HV on−board
supply system are provided with cable glands and ensure an optimum connection of the
shield to the vehicle mass. This guarantees an optimum EMC−compliant installation and
the required environmental conditions are met.
ƒ
When installing the motor cable and the HV on−board cable, slide the cable gland
into the respective holders and fix it by tightening the mounting bracket.
5.4.3 LV on−board cable
Lay the cables LV+ and LV− as close as possible.
I
Tip!
Use angled cable lugs.
5.4.4 HV on−board cable
The descriptions in the next chapter regarding shielded motor cables analogously also
apply to the HV mains cables.
