To prevent possible overloading, each vibrator must have its own motor
protection switch, the tripping current of which must be set in accordance with the
data on the nameplate.
If there are two, counter rotating motors running, it must be ensured that if one
motor fails, both motors switch off at the same time
(see circuit diagram on page 24).
Only flexible cables may be used for connection. We recommend the following
cable types:
HV 0,4 - HV 1:
H 05 RN-F 4G0,75²
HV 2 - HV 85: H 07 RN-F 4G1,5²
from HV 75: NSHTÖU-J 4G1,5² (or H 07 RN-F 4G1,5²)
HV 2 GL: H 07 BQ-F 2x2,5²
HF: H 07 RN-F 4G1,5²
Plastic cables are unsuitable. Attach isolated cable lugs to the wire ends. Under
no circumstances solder cable lugs, as vibrations can cause the stranded wire to
break near the soldering point.
