3 INSTALLATION AND CONNECTION
3.1 MECHANICAL INSTALLATION
3.1.1 Installation Environment
Avoid installing the inverter in an area with:
 Direct exposure to sunlight, rain, high humidity, or sea-air.
 Inflammable or corrosive gases or liquids.
 Excessive vibration.
 Dust, metallic particles, and oil mist.
Environment conditions for the operation of the inverter:
 Inverter surrounding temperature: from -10 ºC up to Ta according to the Table B.4 on page 216.
 For temperatures around the inverter greater than Ta and smaller than 60 °C (frame sizes
A, B, C and D), 40 °C (models with degree of protection IP55) and 55 °C (frame size E), it is
necessary to apply current reduction of 2 % for every degree Celsius (or 1.11 % each °F) up
to Ta.
 Humidity: from 5 % to 95 % non-condensing.
 Altitude: up to 1000 m (3,300 ft) - standard conditions (no derating required).
 From 1000 m to 4000 m (3,300 ft to 13,200 ft) - current derating of 1 % each 100 m (or 0.3 %
each 100 ft) above 1000 m (3,300 ft) altitude.
 From 2000 m to 4000 m (6,600 ft to 13,200 ft) above sea level - maximum voltage reduction
(240 V for 200...240 V models, 230 V for 220...230 V models, 480 V for 380...480 V models
and 600 V for 500...600 V models) of 1.1 % for each 100 m (330 ft) above 2000 m (6,600 ft).
 Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution.
Condensation shall not originate conduction through the accumulated residues.
3.1.2 Mounting Considerations
External dimensions, fixing holes position and net weight of the inverter are presented at Figure
B.2 on page 232 and Figure B.3 on page 234. Please refer to Figure B.4 on page 235 to
Figure B.11 on page 242 for more details of each inverter size.
Install the inverter upright on a flat surface. First place the screws on the surface where the
drive is going to be installed, install the drive and then tighten the screws.
Frame size E inverters with N1 option (CFW700E...N1...):
 After fixing the inverter, install the upper Nema 1 kit on the inverter using the two M8 screws
provided with the product.
