The following notes should assist you to carry out the mechanical installation in a sensible
sequence, without overlooking anything important.

AX2040/2070 Product Manual
Protect the servo amplifier from impermissible stresses. In particular, do not let any compo-
nents become bent or any insulation distances altered during transport and handling. Avoid
contact with electronic components and contacts.
Ensure that there is an adequate flow of cool, filtered air into the bottom of the switchgear
cabinet or use heat exchangers. Observe page 19.
Take care that the servo amplifier and motor are earthed (grounded) properly. Do not use
painted (non-conductive) mounting plates.
Don't mount devices, which produce magnetic fields, directly beside the servo amplifier.
Strong magnetic fields could directly affect internal components. Install devices which pro-
duce magnetic field with distance to the servo amplifiers and/or shield the magnetic fields.
In a closed switchgear cabinet. Observe page 19 .
Site
The site must be free from conductive or corrosive materials.
For the mounting position in the cabinet ð p. 34
Check that the ventilation of the servo amplifier is unimpeded
and keep within the permitted ambient temperature ð p. 19 .
Keep the required space clear above and below the servo amplifier ð p 34.
Assemble the servo amplifier and power supply, filter and choke close
