Section 6 - Specific information for CPVS 40-50-60-75
Refer also to the chapters concerning the standard machine.
"CPVS" compressors are compliant with the Electromagnetic compatibility in industrial environments Standards
The inverter has a load circuit of thermally limited capacitors. Therefore, it is important to allow minimum
45 minutes between two successive

B - Safety
For your safety, please respect the instructions carrying the warning symbols as given below:
SAFETY RULES
The safety rules require:
•The presence of an earth socket
•The existence of a manual switch
•It is necessary to cut out the electric current before any intervention on the machine (except drainage under pres- sure).
= Dangerous voltage
= Attention
ELECTRICAL INSTALLATIONS MUST ONLY BE
CARRIED OUT BY A SPECIALISED AND COMPETENT
TECHNICIANS
1 - Warning
The internal components and the plates (except the electrically insulated I/O terminals) are at the mains
1voltage when the inverter is connected to the mains. This voltage is extremely dangerous and can cause severe injuries or even death in case of involuntary contact.
When the inverter is connected to the mains, the connection terminals U, V, W of the motor as well as
2+/- connectors of the braking resistors are under power even if the motor is not running.
The I/O control terminals are insulated from the mains, the relay outputs can nevertheless be under power
3even if the inverter is disconnected. This also applies to other I/O control terminals even if the X4 switch is in OFF position (Stop).
2 - Safety instructions
No connection work is allowed when the inverter is
1under power.
No measurement work is allowed on the inverter when
2it is under power.
To undertake any work on the inverter, it is necessary to disconnect the equipment from the mains. Wait for
3the internal ventilation to stop and the indicators to be turned off. Then, wait 5 minutes before opening the cover.
No voltage or insulation verification test is allowed on
4the inverter components.
Disconnect the cables from the motor and the inverter
5before taking measurements on them.
Do not touch the integrated circuits, the electrostatic
6discharges may damage them.
Before connecting the inverter, make sure that its cover
7is properly closed.
Make sure that no compensation capacitor of cosine
8phi is connected to the motor cable.
C - Installation
The "CPVS" must be installed away from a transformer or autotransformer.
(see Section 2 and 3).
The fuses for the section switch are defined as follows

ATTENTION
Motors and drives can only be guaranteed where the supply vol- tage does not exceed the rated voltage by more than 10%.
The connection of the power supply to the section switch (so present) requires the use of properly insulated terminals.
