In addition to the electrical protection features, the electric device has mechanical safety feature, a
connector shield, which prevents direct entry to the power terminals, when the electric device is
powered ON. The connector shield is a sheet metal component, which secures the power terminal cover
and it cannot be released without disconnecting the control signal connector (X1-connector) first. When
X1-connector is disconnected, it shuts down the electric device and starts electrical energy discharging
process.

Electromagnetic compatibility (EMC)
When interfacing other equipment, connect only equipment that are specified as part of the
system and that are compatible.
Magnetic and electromagnetic fields generated near the current-carrying conductors and
permanent magnets in electric machines represent a health danger to persons with heart
pacemakers, metal implants and hearing aids. Persons with a heart pacemaker, metal
implants or hearing aids must consult a doctor before they enter the following areas:
•
Areas in which electric equipment and parts are operated
•
Areas in which electric equipment with permanent magnets are stored, mounted,
operated or repaired
If necessary, perform a special electromagnetic compatibility (EMC) test on the installation.
