Section III The Conditions of use and installation
requirements
PR5200(C) series soft starter should comply with the following conditions of use
and installation requirements; otherwise, the performance will not guarantee, it can
shorten life of soft starter even damage.
3-1. The conditions of use of the soft starter
3-1-1. Power supplies: the utility, self-power station, diesel generating sets three-
phase AC 380 V plus or minus 10%, frequency 50 Hz or 60 Hz, the power
supply capacity must meet soft starter motor starting to the requirement
3-1-2. Applicable motor: mouse cage type three-phase asynchronous motor, ac
motor rated power should be matching with soft starter rated power .
3-1-3. Start frequency: no demands, depending on the specific number load up.
3-1-4. Cooling way: air cooling.
3-1-5. The protective level: IP20.
3-1-6. Environmental conditions: Below elevation 3000 meters, the environment
Temperature between -25 ℃ ~ + 40 ℃, relative humidity below 90% RH, no
dewing, no inflammable, no explosive, no corrosive gas easily, have no
electrical conductivity dust, indoor and ventilated good, vibration is less than
0.5 G place.
We can offer under special conditions of use products, such as the explosion
proof type, low temperature, high pressure type type soft starter, its use
conditions will need further instructions.
3-2. The installation requirements of the soft starter
Installation direction and distance: in order to ensure that the soft starter in use
with good ventilation and cooling conditions, soft starter should be installed
vertically, and in the equipment with sufficient heat dissipation space all round,
as shown in chart 3.2 3.1, in the photo, to allow the minimum distance.
Soft starter install inside ark, in addition to the above requirements outside,
still must choose, under ventilated cabinet put oneself in another's position, as
