7 Mechanical Installation
7.1 Important notes
l 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.
l Ensure that there is an adequate flow of cool, filtered air into the bottom of the control
cabinet or use heat exchanger. Note the conditions on page 20.
l Take care that the servo amplifier and motor are properly earthed. Do not use pain-
ted (non-conductive) mounting plates.
l Don't mount devices, which produce magnetic fields, directly beside the servo ampli-
fier. 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.
l Not more than 7 axis modules can be connected to a master module.
7.2 Guide to mechanical installation
The following notes should assist you to carry out the mechanical installation in a sensi-
ble sequence, without overlooking anything important:
Site
In a closed control cabinet. Observe page 20.
The site must be free from conductive or corrosive materials.
For the mounting position within 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.20 .
Keep the required space clear above and below the
servo amplifier
ð p.34.
Mounting
Mount the servo amplifier on mounting rails (DIN-rails) on the
conductive, earthed mounting plate in the control cabinet and
mount the necessary add-on fans (
ð p.36)
Grounding,
Shielding
EMC-conform shielding and grounding (
ð p.45) Earth the moun-
ting plate, motor housing and CNC-GND of the controls. Notes
on connection techniques are on page 40
