Mechanical Installation
7.1
Safety Instructions
There is a danger of electrical shock by high EMC level which could result in injury,
if the servo amplifier (or the motor) isn't properly EMC-grounded. Do not use
painted (i.e. non-conductive) mounting plates.
Protect the servo amplifier from impermissible stresses. In particular, do not let
any components become bent or any insulation distances altered during transport
and handling. Avoid contact with electronic components and contacts.
The servo amplifier will switch-off itself in case of overheating. Ensure that there is
an adequate flow of cool, filtered air into the bottom of the control cabinet, or use a
heat exchanger. Please refer to page 22.
Don't mount devices, which produce magnetic fields, directly beside the servo
amplifier. Strong magnetic fields could directly affect internal components. Install
devices which produce magnetic field with distance to the servo amplifiers and/or
shield the magnetic fields.

Guide to mechanical installation
The following notes should assist you to carry out the mechanical installation in a sensible
sequence, without overlooking anything important.
Site
In a closed switchgear cabinet. Observe page 22 .
The site must be free from conductive or corrosive materials.
For the mounting position in the cabinet
ð
p. 34
Ventilation
Check that the ventilation of the servo amplifier is unimpeded
and keep within the permitted ambient temperature
ð
p. 22 .
Keep the required space clear above and below the servo amplifier
ð
p 34.
Assembly
Assemble the servo amplifier and power supply, filter and choke close
together on the conductive,
grounded
mounting plate in the cabinet.
Grounding
Shielding
EMC-compliant (EMI) shielding and grounding (
