2.5 Commissioning - Preliminary Recommendations
2.5.1 Switching on and the configuration of the inverter
Danger!
RISKS OF ACCIDENTAL DEVICE OPERATION
•
Before turning on and configuring the ACOPOSinverter P84, to avoid an unintended operation
ensure that the PWR input (POWER REMOVAL) is deactivated (state 0).
•
Before you turn on the inverter or when you exit the configuration menu make sure that the
inputs assigned to the operating commands are deactivated (state 0), since these could result
in the immediate starting of the motor.
Failure to follow these instructions will result in death or serious injury.
Caution!
INCOMPATIBLE MAINS VOLTAGE
Before switching on and configuring the frequency inverter, ensure that the mains voltage is compat-
ible with the supply voltage shown on the frequency inverter nameplate. The frequency inverter may
be damaged if the mains voltage is not compatible.
Failure to follow this instruction can result in equipment damage.
2.5.2 Separate voltage supply of the control unit
Only switch on the power supply of the power unit when the inverter is next switched on if:
A) The control unit of the inverter is supplied with power (terminals P24 and 0V) independently of the power unit.
(B) An option card is added or replaced.
2.5.3 On/Off switching of the power supply via the line contactor
Caution!
RISK OF DAMAGE TO THE SYSTEM
•
Avoid frequent operation of the line contactor to prevent premature wear of the filter capacitors.
•
Cycle times of <60 s can damage the pre-charge resistor
Failure to observe these instructions can result in damage to property.
