• In the Soft starter version (CSW40, CSWV 60, CSWV 80 and CSWV 120) it is necessary to install before the
compressor, in the distribution panel, 3-pole circuit breaker/fuses, as shown at Table 6.2.
• Do not wet the Control Panel or its electric components, since water may cause short-circuit and component
burning or electrical shock.
• Install before the compressor, in the distribution panel, a residual 4- pole circuit breaker to ensure greater
safety against electric shock.
• Compressor may restart at any moment, due either to a pressure decrease inside the tank, or to the activa-
tion of the electrical elements.
• Grounding instructions: this product must be grounded. In case of short circuit, grounding reduces the risk of
electric shock through a discharge path of the electric current. Therefore, connect the grounding wire to the
motor's terminal or, if there is no terminal, to the motor's housing.
Note:
The electrical grid must not present a voltage variation over ± 10%.
Voltage drop caused by the start must not be over 10%.
For your safety, the installation must have a grounding conductor and RD.
The Residual Differential (RD) Switch's aim is to protect against electrical shock from direct and indirect contact
with electrifi ed parts.
The Circuit Breaker / Fuse's aim is to protect the compressor against short circuit damage.
The Phase Failure and Phase Sequence Relay's aim is to protect the compressor against motor burning due to
phase failure and block heating due to inversion in spinning or in air circulation.
The purpose of the overload relay is to protect the motor against high electric current, or the compressor in case
of mechanical failure
8. Wiring diagrams and starter switches (orientation)
The diagrams presentS at the end of the manual, show the installation of the power extension, which will be
used for compressor startup, must be done by the client in the Distribution Panel.

Pressure Switch
For products with power up to 1.5 hp, the pressure switch should not be connected directly to the motor, but to
a control circuit (starter), as indicated in the electrical connection guideline diagrams (see the wiring diagrams
at the end of manual). For products with power below 1.5 hp, when the pressure switch is directly connected to
the motor, it must have electrical specifi cations (voltage and current) compatible with the motor. Incorrect use or
non-use of the pressure switch will result in loss of product warranty
•
Starters
Compressors can operate using starters type: direct start, star-delta (YD), or soft-starter. In the case of
soft-starter, it provides fault protection and phase sequence. Regardless of the starter type applied, it should
have overload protection (overload relay).
