Altitude of the installation
location
If the machine is installed at an altitude greater than 1000
meters above sea level:
*Contact your Bush representative, the motor should be
derated or the ambient temperature limited.

*Do not cover fan/cooling outlets.
6.1.4 Preventing Electromagnetic Interferences
Where possible use shielded lines for control circuits.
The shielding should be applied to the line end with special care and without laying the
leads across longer stretches without shielding.
Ensure that no parasitic currents (compensating currents etc.) can flow via the analogue
cable's shielding.
Route the control lines as far away as possible from the power lines. Under certain cir-
cumstances, separate power ducts should be used.
If lines do cross, an angle of 90° should be observed.
Upstream circuit elements, such as protector switches and brake coils, or circuit elements
that are operated via the outputs of the drive controller have to be interference-sup-
pressed. RC circuits are suitable as AC voltage protector switches, while free-wheeling
diodes or varistors are usually used as DC voltage protector switches. These interference
suppression devices are attached directly to the protector switch coils.
NOTE
Where possible, the power for a mechanical brake should be supplied in a separate ca-
ble.
Power connections between the drive controller and motor should always be shielded or
reinforced, and the shielding must have large-scale grounding at both ends! The use of
EMC cable screw connections is recommended. These are not part of the scope of deliv-
ery.
Wiring suitable for EMC must be ensured.
