WARNING
This equipment contains dangerous voltages and controls potentially dangerous
rotating mechanical parts. Non-compliance with the Warnings or failure to follow the
instructions contained in this manual can result in loss of life, severe personal injury
or serious damage to property.
Only suitable qualified personnel should work on this equipment, and only after
becoming familiar with all safety notices, installation, operation and maintenance
procedures contained in this instruction. The successful and safe operation of this
equipment is dependent upon its proper handling, installation, operation and
maintenance.
The power supply, DC and motor terminals, the brake and thermistor cables can
carry dangerous voltages even if the inverter is inoperative. Wait at least five minutes
to allow the unit to discharge after switching off the line supply before carrying out
any installation work. It is strictly prohibited for any mains disconnection to be
performed on the motor-side of the system; any disconnection of the mains must be
performed on the mains-side of the Inverter.
When connecting the line supply to the Inverter, make sure that the terminal case of
the motor is closed. When changing from the ON to OFF-state of an operation if an
LED or other similar display is not lit or active; this does not indicate that the unit is
switched-off or powered-down.
The inverter must always be grounded. Isolate the line supply before making or
changing connections to the unit. Ensure that the inverter is configured for the
correct supply voltage. The inverter must not be connected to a higher voltage
supply.
Take particular notice of the general and regional installation and safety regulations
regarding work on dangerous voltage installation (e.g. EN 50178) as well as the
relevant regulations regarding the correct use of tools and personal protective
equipment (PPE).
