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
.
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
and
. Please refer to
to
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.
