ELECTRICAL CONNECTIONS
General
The apparatus is designed according to the standard EN60204-1.
All wiring on site must conform to the legal standards in force in the country concerned and the EN60204-1.
Wiring of electric motors
In all cases to comply with the indications in the junction of the evaporator box.

Index of Protection
Class of insulation
The standard three-phase motors are of the type slip.
Standard single phase motors are with permanent capacitors.
Indices of data protection obturés drain holes (IEC 34-5).
Attention
: the maximum imbalance between phases is 2% in voltage and 10% intensity by engine.
If the motors with a variable speed (voltage dimmer or frequency drive) control, mandatory contact PROFROID INDUSTRIES.
Electric defrost
Defrost resistors are elements to under 230 V between phase and neutral point.
In the case of an application of House at 0 ° C, must be electrically deice the battery.
Below 0 ° C applications, it is necessary to provide resistors in the tray.
Defrost resistors are mounted in copper and blocked sheaths at the ends by two clips.
Defrost thermostat or limiters to be imperatively crossing of atmosphere.
Anti fire thermostats are not part of the standard supply.
Water flow must be equipped with resistance to flow.
Electric protections
For electric motors, they must conform to the standards in force and be graded on the nominal amperage plated used speed.
Electrical resistors, protection is linked to the neutral plan:
-Neutral TT: differential circuit breaker 300 mA.
-Neutral IT: fuse.
-TN neutral: we recommend the establishment of a differential circuit breaker 300 mA.
The neutral is distributed, it will connect the resistance star point.
(Attention, on some models, the neutral point can be located in the opposite cheek).
START-UP OPERATIONS

PRELIMINARY INSPECTION
Check the tightening of various nuts fixation of motoventilateurs (possible loosening during transport).
Check that there is no disruption of piping (possible break in transit).
CONTROL OF SEAL
Version dry expansion
Pressure will be set on the complete circuit with a neutral gas (nitrogen R) completed with a tracer (not liquid and not coloured) to
a minimum pressure equal to 1 time to Ps in accordance with the EN 378-2
