Safety instructions 1
Before installing and putting this equipment into operation, read the following safety
instructions and all warning labels attached to the equipment carefully. Make sure the
warning labels are kept in a legible condition and replace missing or damaged labels.
General
DANGER
Dangerous voltage
Do not touch any terminals within five minutes after the power supply for the inverter has
been switched off. Hazardous voltage remains present in the internal DC link capacitors
when the power is removed. Failure to follow this instruction could cause electric shocks.
Protective earthing conductor current
As the earth leakage for the inverter can be greater than AC 3.5 mA, 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 inverter can cause a DC current in the protective earthing conductor.
WARNING
This equipment contains dangerous voltages and controls potentially dangerous rotating
mechanical parts. Loss of life, severe personal injury, or property damage could result if the
instructions contained in this manual are not followed.
Only suitable qualified personnel should work on this equipment, and only after becoming
familiar with all safety instructions, installation, commissioning, operation, and maintenance
procedures contained in this manual.
Any unauthorized modifications of the equipment are not allowed.
Protection in case of direct contact by means of voltages < 60 V (PELV = Protective Extra
Low Voltage according to EN 61800-5-1) 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.
The inverter must always be grounded. If the inverter is not correctly grounded, this can
lead to extremely hazardous conditions which, under certain circumstances, can result in
death.
The device must be disconnected from the electrical power supply before any connections
with the device are established or in any way altered.
Install the inverter on a metal mounting plate in a control cabinet. The mounting plate has to
be unpainted and with a good electrical conductivity.
It is strictly prohibited for any mains disconnection to be performed on the motor-side of the
system, if the inverter is in operation and the output current is not zero.
Take particular notice of the general and regional installation and safety regulations
regarding work on dangerous voltage installations (e.g. 61800-5-1) as well as the relevant
regulations regarding the correct use of tools and personal protective equipment (PPE).
