3.6.4 Screened motor cable for RASP5.
3.6.4.1 General notes
The following information uses the example of a DESINA MOTORFLEX cable
with 4G1.0 2 x (2 x 0.75), to describe the steps required for the EMC connec-
tion of a mains cable to the RASP5.

▶ Stripping the motor cable ends (radial and longitudinal cut).
▶ Push the screen braid back to reveal the individual conductors.
▶ The conductors B1 (= N) and B2(= L) for the external brake as well as T1
and T2 for the thermistor have a sheath and a separate screen braid.
These conductors must be stripped separately.
▶ Then slide the outer screen braid of the motor cable back toward the
cable end far enough that conductors B1/B2 and T1/T2 are covered over
a large area and connected with each other.
￫
To strip the cable, set the blade so that the conductor insulation
and the screen braid remain undamaged.
￫
Wrap insulating or textile tape or slide a rubber grommet around
the screen ends to prevent the screen braid from splicing.
