4 Electrical installation

WARNING
Dangerous voltage!
When the frequency inverter is disconnected from power supply,
the mains, DC-link voltage and motor terminals may still be live
for some time. Work at the device may only be started once the
DC link capacitors have discharged. The time to wait is at least
3 minutes for devices of sizes 1 through 7 and at least 10 minutes
for devices of size 8.
 The electrical installation must be carried out by qualified
electricians according to the general and regional safety and
installation directives.
 The documentation and device specification must be
complied with during installation.
 Before any assembly or connection work, discharge the
frequency inverter. Verify safe isolation from power supply.

Do not connect inappropriate voltage sources. The nominal
voltage of the frequency inverter must correspond to the
supply voltage.
 The frequency inverter must be connected to ground
potential.

Do not remove any covers of the frequency inverter while
power supply is on.
NOTICE
Unexpected currents
Please note (according to EN61800-5-1): This product, especially
if used in combination with connected components, can cause a
direct current in the protective earth conductor.
 Where residual current devices (RCD) or residual current
monitors (RCM) are used as a protection against direct or
indirect contact, only RCDs / RCMs of Type B are permissible
on the power supply side of this product.
