5 INSTALLATION AND CONNECTION
5.1 RECEIVING AND STORING
When receiving the CTW900, check on the label on the external part of the package if the smart code
corresponds to the model ordered.
Then, confirm on the product nameplate (attached to the side of the converter) if the model received matches
the description on the package, and if any damages occurred during transportation.
If any problems are detected, contact the carrier immediately.
If the CTW900 is not installed soon, store it in a clean and dry location (temperature between -25ºC and 60ºC),
with a cover to prevent dust accumulation inside it.
5.2 MECHANICAL INSTALLATION
5.2.1 Environmental Conditions
The location of the converter is determinant for its proper operation and normal useful life of its parts.
Thus, it is recommended to avoid installing it in the following conditions:
■
direct exposure to sunlight, rain, high humidity or sea-air;
■
explosive or corrosive liquids or gases;
■
excessive vibration;
■
dust, metallic particles or oil mist.
Accepted operating and environmental conditions:
■
Temperature:
-
0 °C to 40 °C – rated conditions;
-
40 ºC to 50 ºC – 2 % of current derating for each Celsius degree above 40 ºC;
■
Air relative humidity: 10 % to 90 % non-condensing;
■
Altitude:
-
0 to 1000 m – rated conditions;
-
1000 m to 4000 m – 1 % current derating for each 100 m above 1000 m;
■
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. Condensation must
not originate conduction through accumulated residues.
5.2.2 Positioning and Mounting
For the proper operation and heat dissipation, the CTW900 must be installed only in the vertical position on a
flat surface.
Furthermore, we recommend following the instructions below:
■
keep the minimum clearances indicated in Figure 5.1;
■
do not put sensitive component parts right above the converter;
■
if mounting a converter next to another, use the minimum distance 2xB;
■
if mounting a converter above another, use the minimum distance A+C and deflect the hot air coming from
the lower converter so as not to hit the upper converter;
■
drill the mounting holes according to Figure 5.2;
■
provide independent conduits or gutters for physical separation of the signal, control and power conductors
(refer to section 5.3 – Electrical Installation), also separating the motor cables from the other cables.
NOTE!
For converters installed inside cabinets or metal boxes, provide proper exhaustion, so that the
temperature remains within the allowed range.
