Connect the input power and motor cables properly; otherwise, the inverter unit
may be damaged.
Cut off all power supplies connected to the inverter unit before terminal wiring, and
wait for at least the time designated on the inverter unit after disconnecting the
power supplies.
High voltage presents inside the inverter unit during running. Do not carry out any
operation on the inverter unit during running except for keypad setup. For products
at voltage class of 4 or 6, the control terminals form extra-low voltage circuits.
Therefore, you need to prevent the control terminals from connecting to accessible
terminals of other devices.
Before turning on the power supply, check the cable connection status.
Prevent anyone from directly touching the energized part of the cabinet door. Pay
special attention to safety when handling shields that are made of metal sheets.
Do not do any withstand voltage testing during unit connection. Disconnect the
motor cable before performing any insulation and voltage withstand tests for the
motor or motor cable.
Do not open the cabinet door since high voltage presents inside the Goodrive800
Pro series product during running.
Do not switch on or switch off the input power supplies of the inverter unit
frequently.
If the inverter unit has been stored for a long time without use, perform checking
and carry out pilot run for the inverter unit before using it again.
Close the inverter unit front cover before running; otherwise, electric shock may
occur.
Only trained and qualified professionals are allowed to perform maintenance,
inspection, and component replacement for the inverter unit.
Cut off all power supplies connected to the inverter unit before terminal wiring,
and wait for at least the time designated on the inverter unit after disconnecting
the power supplies.
During maintenance and component replacement, take measures to prevent
screws, cables and other conductive matters from falling into the internal of the
inverter unit.
Use proper torque to tighten screws.
During maintenance and component replacement, keep the inverter unit and its
parts and components away from combustible materials and ensure they have no
combustible materials adhered.
Do not carry out insulation voltage-endurance test on the inverter unit, or
measure the control circuits of the inverter unit with a megohmmeter.
During maintenance and component replacement, take proper anti-static
measures on the inverter unit and its internal parts.
