Danger to life due to fire or electric shock when using unsuitable residual current protection
devices
The inverter can cause a current to flow in the protective conductor. This current can cause
the residual current device (RCD) or residual current monitoring (RCM) to incorrectly trip
(nuisance trip). In the case of a fault (ground fault), the fault current can contain a DC
component, which prevents the RCD/RCM from tripping, with the risk of subsequent fault or
electric shock.
• Use the protection and monitoring devices recommended in the documentation.
Risk of injury due to hot surfaces
During operation and for a short time after the inverter shuts down, the surface of the
device can reach a high temperature.
• During this time, avoid any direct contact with the surface of the inverter.
Danger to life through electric shock as well as fire hazard due to protective devices that
either do not trip or trip too late
Overcurrent protective equipment that trips too late or not all can cause electric shock or
fire.
• In the case of a conductor-conductor or conductor-ground short-circuit, ensure that the

Protection and monitoring equipment
To provide protection against short-circuit, use the overcurrent devices listed in Technical
data (fuses, circuit breakers etc.).
If the apparent impedance of the line supply at the infeed point is not suitable, so that fuses
do not rupture in the specified time in the case of insulation failure (ground fault, fault to
frame), then you must use additional fault current protective devices RCD (RCCB or MRCD),
type B.
