Installation safety
Only trained and quali ed personnel familiar with the relevant safety requirements can install the electric device. If the
electric device is installed incorrectly it may lead to safety hazard.
Do not do any ash tests or voltage withstand tests on the electric device. If electrical tests or measurements are required,
do the tests with the electric device disconnected and stored energy discharged.
Disconnect and isolate the electric device before you start any work on it. High voltages are present at the terminals and
within the inverter. Passive discharging of the DC-link capacitor is done by the bleeder-resistor. Discharging below 50
Volts is completed within 8 minutes after the power is disconnected. Make sure that voltage is not present on any inverter
power terminals prior you start any work on it.
Make sure of correct grounding connections. Do not run the electric device without correctly attached protective earth
conductor. The grounding cable must be sufficient to carry the maximum supply fault current which is normally limited
by the fuses or Miniature Circuit Breaker (MCB). Suitably rated fuses or MCB should be tted in the mains supply of the
electric device, by the local legislation and recommendations.
Use only correct (type and value) protective fuses with the high voltage DC-system.
Do not do any work on the electric device control cables when the power is applied to the electric device or to the external
control circuits.
The control input functions of the electric device – for example stop/start must be secured using independent channel
protection in safety critical applications. All applications where malfunction could cause injury or loss of life must be
subject to a risk assessment and improve control signal protection if needed.
The electric device can start at power up if the start- input signal is present.
The STOP function does not remove potentially lethal high voltages. Isolate the electric device and wait for 8 minutes
before you start any work with it. Never do any work on the electric device, external devices or electric cables if the input
power is connected to the electric device.
Do not activate the automatic fault reset function on any system, where this may cause a potentially dangerous
situation. Reason for every fault situation should be determined before resetting the fault.
Make sure that the supply voltage corresponds to the speci cation of the electric device.
Do not attempt to repair the electric device. In the case of suspected fault or malfunction, contact Danfoss or
Danfoss authorized service center for further assistance.
When you install the electric device, make sure that the cooling system and the used coolant meet the speci cations of
the manufacturer. Make sure that the cooling system is in use when the DC-link is powered.
