3 INSTALLATION AND CONNECTION

This chapter describes the electric and mechanical installation procedure of the SCA06. The directions and
suggestions must be observed so as to ensure the safety of people, equipment and proper operation of the
servo drive.

3.1 MECHANICAL INSTALLATION

3.1.1 Environmental Conditions

Avoid:
Direct exposure to sunlight, rain, high humidity or sea-air.
„
Inflammable or corrosive liquids or gases.
„
Excessive vibration.
„
Dust, metallic particles or oil mist.
„
Environment conditions permitted for the operation of the inverter:
Ambient temperature: 0 ºC (32 °F) to 50 ºC (122 °F) - rated conditions (measured around the servo drive).
„
From 50 ºC (122 °F) to 60 ºC(140 °F) - 2 % of current derating for each Celsius degree above 50 ºC (122°F).
„
Air relative humidity: 5 % to 90 % non-condensing.
„
Maximum altitude: up to 1000 m (3280 ft)- rated conditions.
„
1000 m (3280 ft) to 4000 m (13123 ft) - 1 % of current derating for each 100 m (328 ft) above 1000 m (3280 ft)
„
of altitude.
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. Condensation must
„
not originate conduction through the accumulated residues.

3.1.2 Positioning and Mounting

Check the weight of the servo drive in
Install the servo drive in the vertical position on a flat surface, preferably on a galvanized and grounded plate.
Check the external dimensions and position of the fixation holes in
refer to section 9.3 MECHANICAL DATA on page
Put the first bolt on the surface where the servo drive will be installed, install the servo drive and then tighten the bolt.
Allow the minimum clearances indicated in
It is possible to mount the servo drives side by side without side clearances.
Do not put sensitive component parts right above the servo drive.
ATTENTION!
When one servo drive is installed above another, use the minimum distance B1 + C1
