INSTALLATION AND CONNECTION
This chapter describes the procedures for the electrical and
mechanical installation of the Soft-Starter SSW-07. The guidelines
and suggestions must be followed for the correct operation of the
Soft-Starter SSW-07.
The location of the Soft-Starters SSW-07 is an important factor to
assure the correct operation and high product reliability.
Avoid:
 Direct exposure to sunlight, rain, high moisture and sea air ;
 Exposure to explosive or corrosive gases and liquids;
 Exposure to excessive vibration, dust or any metallic and/or oil
particles in the air.
Allowed Environmental Conditions:
 Surrounding air Temperature: 0 ºC to 55 ºC (32 ºF to 131 ºF) -
nominal conditions.
 Relative air moisture: 5 % to 90 %, with no-condensation.
 Maximum altitude: 1,000 m (3,300 ft) above sea level - nominal
conditions.
From, 1,000 m to 4,000 m (3,300 ft to 13,200 ft) above sea level -
current reduction of 1 % for each 100 m (330 ft) above 1,000 m
(3,300 ft).
From 2000 m to 4000 m (6,600 ft to 13,200 ft) above sea level -
voltage reduction of 1.1 % for each 100m (330 ft) above 2,000 m
(6,600 ft).
 Pollution degree: 2 (according to the UL508).
Normally, only non conductive pollution. Condensation must not
cause conduction in the particles in the air.
