Leakage current, securely attached, protective earth conductor
Danger due to electric current
The maximum leakage current depends on the type of device and the connected mains voltage (
Technical Data). With regard to
fi
xed connection and the type of PE conductor connection, the
speci
fi
cation for the leakage current must be observed under consideration of the locally valid
standards (for Europe
EN 50178 Section 5.2.11 or 5.3.2.1 etc.).
Minimum cross-section for PE conductor for
fi
xed connection = 1.5 mm

Residual-current-operated protective device
Danger due to electric current
For an installation of r.c.d. protection, it shall be observed that this must be of
“
universal-current
sensitivity
”
(Type B). In accordance with EN 50 178, Section. 5.2. other types of current-operated
protective devices may not be used. To ensure as high a degree of reliability as possible , we
recommend a tripping current of 300 mA.

Motor connection
The motor leads are connected to the terminals: PE, U, V, W. Comply with the motor data (rating
plate) regarding the type of connection (Y or D) (
U / f-characteristic curve and technical data).
Information
•
For each Controller can be attached only one motor, parallel operation of several motors is not
allowed!
•
The maximum length of the screened motor cable is 10 m, a longer cable is not permissible!
5.5.2
Disconnection between controller and motor (repair switch)
Ideally, a repair switch should be installed
before the controller
(supply line disconnect).
In the case of complete disconnection (entire load) after the controller, the enable (controller OFF /
ON) must be disconnected simultaneously. I.e., an additional control contact is needed. Switching on
the motor while simultaneously issuing the enable (ON) achieves secure energizing with low
saturation of the controller.
Attention!
When switching on the motor plus existing release: under certain circumstances, this can occur under
full modulation of the controller.
