2.4.1 Important Notes
CAUTION
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-groun-
ded. Do not mount the servo amplifier to painted (i.e. non-conductive)
mounting plates. 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 itself off 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.
Do not mount devices that produce magnetic fields directly beside the servo amplifier. Strong
magnetic fields can directly affect internal components. Mount devices which produce mag-
netic field with distance to the servo amplifier and/or shield the magnetic fields.
2.4.2 Guide to Mechanical Installation
Material 3 hexagon socket screws to EN 4762, M5
Tool required 4 mm Allen key
The following notes should assist you to carry out the mechanical installation in a sensible
sequence, without overlooking anything important.
Site Mount in a closed switchgear cabinet.
The site must be free from conductive or corrosive materials.
For the mounting position in the cabinet refer to (➜ # 144).
Ventilation Check that the ventilation of the servo amplifier is unimpeded and keep
within the permitted ambient temperature (➜ # 42).
Keep the required space clear above and below the servo amplifier (➜ #
144).
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 see Instructions Manual.
Earth (ground) the mounting plate, motor housing and CNC-GND of the
controls.
