Attention
Electrical work must only be carried out by a qualified expert.
Make sure that the electrical connection of weatherproof units is water tight. Connection
from below or waterproof unions (at least protection rating IP 65, use sealings) with
sufficient cable radius.
Check all electrical connections (switch cabinet, frequency converter, motor etc.) for correct
seating and retighten if necessary (see also DIN 46200).

Electrical components such as electric air heaters, electric motors, actuators, etc. should be
connected and grounded according to manufacturer’s specifications, local electrical
regulations as well as general recommendations concerning the prevention of
electromagnetic interferences (grounding, cable lengths, cable shields, etc.).
The connection tags are attached in the terminal box.
All existing ground straps (equipotential bondings) shall be inspected and, if necessary,
readjusted/retightened.
Electrical safety inspections should take place in accordance with DIN EN 60204 (VDE
0113) and by adhering to all required safety precautions.
The on-site power supply must fulfill the requirements cited in DIN EN 60204, Table 10.
According to nationally valid regulations, the operator is obligated to repeat these inspections
on a regular basis.
In Germany, the periodic intervals of the repeated inspections according to VBG 4 §5 Table
1A (Repeated inspections of stationary electrical units and equipment) must be observed.

Motor Protection

Protect motors against overload in accordance with DIN EN 60204 (VDE 0113).
Provide motor protection switch and adjust to the motor nominal current (see nameplate).
A higher set value is not permissible!
Protect motors with integrated PTC thermistor sensors via a PTC release device.
Motors with a nominal power up to 3 kW can generally be switched on directly (observe
power limitations of the responsible energy supply company). For larger motors provide
star-delta circuit or soft start up.
Permanent-magnet synchronous motors must not be operated directly on the net without
extra motor electronic (e.g. appropriate frequency converter) (net-bypass-operation is not
possible).
