15 ELECTRICAL CONNECTIONS

15.1 Power connection

The units are designed in accordance with the requirements of
European standard EN 60204-1.
They comply with the requirements of the machinery and
EMC directives.
All wiring must be connected in accordance with the codes and
regulations that apply to the installation site (e.g. NFC 15100
in France).
In all cases:
- Refer to the wiring diagram attached to the unit.
- Follow the electrical supply specifications indicated on the
data plate.
The voltage must remain within the range indicated:
– Power circuit:
400 V (+10%/-10%) - 3-ph - 50 Hz + Earth
* 230 V (+10%/-10%) - 3-ph - 50 Hz + Earth
- Control circuit:
1 ~ 50 Hz 230 V (Transformer fitted as standard on the
machine)
* Installation according to French regulations
- Phase unbalance must not exceed 2% and 10% for voltage
and current, respectively.
If any of the above requirements are not met, contact your
power supplier immediately and make sure the unit is not
turned on until the necessary corrective actions have been
taken. Failure to do so will automatically void the CIAT
warranty.
Wiring is to be sized by the installer to suit the characteristics
of the installation site and comply with applicable regulations.

15.2 Customer connection for remote control functions.

Certain operating states can be wired directly to terminal X1 provided for this purpose:
add 2 board
CPU board
Once the size of the wires has been selected, the installer must
determine any changes needed on site to facilitate connection.
- Wiring must be selected based on:
• The maximum rated current (refer to the "Electrical
specifications").
• The distance between the unit and its power source.
• The protection to be fitted at the power source.
• The neutral mode.
• The electrical connections (refer to the wiring diagram
provided with the unit).
- The electrical connections are to be made as follows:
• Connection to the power circuit.
• Connect the protective conductor to the earth terminal.
• Connect the general fault display dry contact and the
automatic operation control dry contact (where applicable).
• Interlock the compressors with the accelerator pump.
- The external control must be connected using a potential-free
(dry) contact.
- The disconnect switch has a breaking capacity of:
• 40.5 kA for DYNACIAT
models,
• 61.5 kA for DYNACIAT
models,
• 70 kA for DYNACIAT
The unit is supplied by the upper right section of the electrical
cabinet with an opening for routing the supply cables.
