1.- RS 485 communications output to connect various inverters. Up to 4 units.
2.- Auxiliary input for an external level switch or a potential-free contact to activate or stop the circuit.
Note: This input is supplied from the factory with an electric cable bridge.
3.- Input of the 4-20mA pressure transducer.
4.- Potential-free auxiliary input. Not used.
5.- Auxiliary transducer input. Not used.
6.- Only in single-phase versions. 230 V potential output, 2A maximum, external display or acoustic
operation for alarm signals.
7.- Micro-switches used to configure the inverter's operation.
WARNING: All external cabling connections must use terminal tips on the ends of each cable. External
cables must comply with the corresponding electrical safety and insulation regulations. Installation
should be made by qualified service personnel.
Avoid any cable pieces from falling inside the circuit, which could lead to its destruction.
DANGER. Risk of electrocution.
If the unit has to be uncovered due to any circumstance, first disconnect the power supply and wait 5
minutes before starting work with the circuit. The circuit's capacitors store energy. There is enough
energy inside the circuit to cause a strong electric discharge, even when the unit is not powered.
