Safety instructions
General
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.
Protection in case of direct contact by means of SELV / PELV is only permissible in areas
with equipotential bonding and in dry indoor rooms. If these conditions are not fulfilled,
other protective measures against electric shock must be applied e.g. protective insulation.
Only suitably qualified personnel should work on this equipment, and only after becoming
familiar with all safety notices, installation, operation and maintenance procedures
contained in this manual. The successful and safe operation of this equipment is dependent
upon its proper handling, installation, operation and maintenance.
As the earth leakage for this product can be greater than 3.5 mA a.c., a fixed earth
connection is required and the minimum size of the protective earth conductor shall comply
with the local safety regulations for high leakage current equipment.
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.
This equipment is capable of providing internal motor overload protection according to
UL508C. Refer to P0610 and P0335, i²t is ON by default.
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.
Static discharges on surfaces or interfaces that are not generally accessible (e.g. terminal
or connector pins) can cause malfunctions or defects. Therefore, when working with
inverters or inverter components, ESD protective measures should be observed.
Take particular notice of the general and regional installation and safety regulations
regarding work on dangerous voltage installations (e.g. EN 50178) as well as the relevant
regulations regarding the correct use of tools and personal protective equipment (PPE).
