Emerson CSS Serie Instructions De Service

General information and technical data:
Compressor Soft Starters of the CSS-Series are used to limit
1-phase compressors. For additional start torque a built

of alarm a signal is indicated by the red LED. The alarm relay will be activated.
Soft starters are released for use with many compressors. (See list Fig.3)

Safety instructions:
• Read installation instructions thoroughly. Failure to comply can result in Read installation instructions thoroughly. Failure to comply can result in
device failure, system damage or personal injury.
• It is intended for use by persons having the appropriate knowledge and It is intended for use by persons having the appropriate knowledge and
skill.
• Unauthorised opening of the Soft Starter will void warranty.
• Switch off all voltages / currents before connecting wiring
• Comply with local electrical regulations when wiring.
• Do not exceed operating temperature.
• Do not operate system before all cable connections are completed.
Setting:
• No setting required. The Soft Starters automatically limit
based on the connected compressor size. Several consecutive starts are required
to learn and and optimise the start current of the attached comp to learn and and optimise the start current of the attached compressor.
Mounting – Dimensions See Fig. 2:
• CSS Soft Starters are for mounting in electrical switch board
mounting clip allows convenient DIN rail fixing; for secure mounting on any
other flat surface, it has four drill holes (Ø4.5mm). The mountin
attached to the housing base in two directions, see fig. 5. attached to the housing base in two directions, see fig. 5. Protect CSS from
direct sun light and water.
Wiring (Fig. 2):
• Perform wiring as printed on the housing. CSS Contacts:
R Output motor run winding
RC Output run capacitor

C. Releasing current 25A for CSS-25U, 32A for CSS-32U.
• Warning: Do not use an additional contactor. CSS could be damaged.
• Warning: Do not connect "Crun" capacitor to the "Run" lead of the motor.
Connect it between RC and S terminals as per wiring diagram.
start capacitor "Cstart" is built in the Soft Starter.
• The terminals are for flexible cable cross section 0.2 ... 4
• The screws must be tightened with 0.5... 0.6 Nm.
• The wiring diagram per Fig.1 is an example how safetyfunctions can be wired. The wiring diagram per Fig.1 is an example how safetyfunctions can be wired.
