SAFETY INSTRUCTIONS
IMPORTANT!
Read carefully this manual to maximize the performance of the
product and to ensure its safe use.
In order to use appropriately the drive, please, follow all instructions
described in the installation manual referred to transport, installation,
electrical connection and commissioning of the equipment.
Power Electronics accepts no responsibility or liability for partial or
total damages resulting from inappropriate equipment use.
Please, pay careful attention to the following recommendations:
WARNING
Make sure to take ESD (Electrostatic Discharge) protection measures
when you touch the board.
Otherwise, the optional board may get damaged due to static charges.
Implement wiring change on the optional board after checking that the
power supply is off.
Otherwise, there is a danger of connecting error and damage to the
board.
Be sure to connect correctly the optional board to the inverter.
Otherwise, there is a danger of connecting error and damage to the
board.
Do not remove the cover while the power is applied or the unit is in
operation.
Otherwise, electric shock could occur.
Do not run the inverter with the front cover removed.
Otherwise, you may get an electric shock due to the high voltage
terminals or exposure of charged capacitors.
Do not remove the cover except for periodic inspections or wiring,
even if the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.

SAFETY INSTRUCTIONS
Wiring and periodic inspections should be performed at least 10
minutes after disconnecting the input power and after checking the
DC Link voltage is discharged with a meter (below 30VDC).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use cables with damaged insulation.
Otherwise, you may get an electric shock.
Do not subject the cables to the abrasions, excessive stress, heavy
loads or pinching.
Otherwise, you may get an electric shock.
CAUTION
Install the drive on a non-flammable surface. Do not place
flammable material nearby. Otherwise, a fire could occur.
Disconnect the input power if the drive gets damaged.
Otherwise, it could result in a secondary accident or fire.
Do not allow lint, paper, wood chips, dust, metallic chips or
other foreign matter into the drive. Otherwise, a fire or
accident could occur.
The inverter becomes hot during operation. Wait until it
cools down before performing any actions.
Touching hot parts may result in skin burns.
Do not apply power to a damaged drive or to a drive with
parts missing, even if the installation is complete.
Otherwise, you may get an electric shock.
