1. PEOPLE SAFETY
RISKS OF ELECTROCUTION OR EXPLOSION

Read carefully this installation guide before using the inverter.

The user has to conform to all the requirements of the international and national regulations about the
earthing of all the equipments.

DO NOT touch the internal parts of the inverter : use only tools isolated electrically

DO NOT touch the terminal blocks when the inverter is supplied.

DO NOT put in short circuit borders DC+1 and DC+2 or condensers of the bus DC. A high tension which
can cause electric shocks remains present in the device after cutting the supply.

DO NOT try to fix the inverter; you should contact your retailer.

Put back in place and close all the lids before putting back the inverter under tension.

The inverter must be carefully fixed before switching it under tension.

Before any intervention on the motor, power supply of the inverter must be turned off.
NON-RESPECT OF THESE RULES MAY BE FATAL: DEATH, SERIOUS INJURIES AND MATERIAL DAMAGES
2. MATERIAL SAFETY

Verify that the inverter VFR-013 is not damaged

Verify that the inverter corresponds to your order and to the delivery note.

Verify that the tension of the electric network corresponds to the supply power of the inverter : 220V
single phase or 400V three phase

Never turn off the supply power if the inverter before the end of the motor operations.

An armored cable must be used for the control circuit, and this one must be taken away as much as
possible from the circuit of power to avoid the disturbances.

When the frequency of hashing is lower than 3 KHz, the distance between the inverter and the motor
must be at the maximum 50 meters.

If the inverter has to start frequently, do not turn off it power supply, but use the starting up at the
terminal blocks, to avoid some damages.

Never connect a supply power on terminals U, V, W of the inverter; otherwise it would be immediately
destroyed.

The inverter capacity in KW and A should always be higher than the motor capacity.
WARNING; IF THE INVERTER IS DAMAGED; DO NOT USE IT
