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 50081-2 and 50082-2

The inverter has a load circuit of thermally limited capacitors. Therefore, it is important to allow minimum

45 minutes between two successive power-ons. If this instruction is not respected, the switch and the resistor of the load circuit may be damaged.

A - Description (cf Section 1)

Standard equipment

A electronic frequency adjusting device replaces the star-delta starter.

A fuse holder section switch completes CP standard's safety devices.

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 cutting-off the three pha- ses that should be placed visibly near the CP

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).

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.
