5 INSTALLATION AND CONNECTION
5.1 RECEIVING AND STORAGE
On the outside of the ECW500 package there is a label similar to the label that is affixed on the side of the
product.
Make sure the ECW500 identification label corresponds to the model purchased or if there were any damages
during transport.
If any problem is detected, contact the carrier immediately.
If the ECW500 is not installed soon, store it in a clean and dry location (temperature between -40 F and 185 F),
with a cover to prevent dust accumulation inside it.
5.2 MECHANICAL INSTALLATION
5.2.1 Environmental Conditions
The location of the voltage regulator 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:
-
-40 °C to 50 °C (-40 F to 122 F) rated conditions;
-
50 ºC to 60 ºC (122 F to 140 F) 2 % of current derating for each Celsius degree above 50 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
The ECW500 should be mounted inside electrical panels and can be positioned both horizontally and vertically.
Furthermore, we recommend following the instructions below:
■ keep a minimum clearance of 60 mm on all sides of the regulator in relation to the walls of the panel;
■
do not put sensitive component parts right above the regulator;
■ if mounting a regulator next to another, use the minimum distance of 120 mm;
■ if mounting a regulator above another, use the minimum distance of 120 mm and deflect the hot air coming
from the lower regulator;
■ drill the mounting holes according to Figure 5.1;
■ 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 machine cables from the other cables.
NOTE!
For regulators installed inside cabinets or metal boxes, provide proper exhaustion, so that the
temperature remains within the allowed range.
