7 Mechanical Installation
7.1 Important notes
CAUTION
High leakage current! There is a danger of electrical shock by high EMC
level which could result in injury, if the servo amplifier (or the motor) is not
properly EMC-grounded.
l
Do not use painted (i.e. non-conductive) mounting plates.
l
In unfavourable circumstances, use copper mesh tape between the
earthing bolts and earth potential to deflect currents.
Protect the servo amplifier from impermissible stresses. In particular, do not let any com-
ponents 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 28.
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.
7.2 Guide to mechanical installation
The following notes should help you to carry out the mechanical installation.
Site
In a closed control cabinet. Please refer to page 28.
The site must be free from conductive or corrosive materials.
For the mounting position in the cabinet ð p.46.
Ventilation
Check that the ventilation of the servo amplifier is unimpeded, and
keep within the permitted ambient temperature ð p.28. Keep the re-
quired space clear above and below the servo amplifier ð p.46.
Assembly
Assemble the servo amplifier and power supply close together, on
the conductive, grounded mounting plate in the cabinet.
Grounding
Shielding
For EMC-compliant shielding and grounding ð p.57.
Ground the mounting plate, motor housing and CNC-GND of the
control system. Notes on connection techniques ð p.52.
