t and Installation
The power supply provided by the customer (voltage, phases, and frequency) must be correct and sufficient to
adequately power the equipment. Specifically, the following requirements must be met:
•
If required for a particular equipment configuration, install a differential electromechanical
circuit breaker
between the power supply line and the door lock switch installed on the equipment. This switch must be
adequately sized to the application and in compliance with local codes and ordinances. Make sure that the
supply voltage is the same as that shown on the plate and wiring diagram of the equipment; the permissible
tolerance is ±10% of the rated voltage. In case of presence on the equipment of user devices that generate
earth fault currents with high continuous and/or high-frequency components
(inverter, UPS, etc.), use a class
differential thermal breaker suitable for use with such non-linear
circuits.
ATTENTION: The differential electromechanical circuit breaker must be placed in the immediate
vicinity of the equipment so that it can be clearly visible and reachable by the technician while
performing maintenance.
• The gauge of the power supply cable must be adequate for the power rating of the equipment. For further
information on the total amp draw of the equipment, refer to the wiring diagram attached to this manual.
• The power supply cable must have construction characteristics that are suitable for the conditions of the
installation site of the equipment.
The unit is equipped with an electrical panel for power and control. In general it has the following functions:
• General switch with door lock
• Electromechanical protection of all loads
• Electronic control terminal
• Compressors protected by clectromechanical switches
• Power transformer for control circuits
• Management of the maximum (and optional minimum) pressure switches each according to its functionality
In the electrical panel, there is a customized electronic controller with different functions:
• Regulation with pressure or temperature probe
• Compressor operation management
• Control of the compressor work area
• Alarm management
• Oil management
