5.3.2 Required quality attributes for the mains voltage
Danger due to electric current
The mains voltage must comply with the EN 50160 quality characteristics and the
defined standard voltages in IEC 60038!
5.3.3 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 fixed connection and the type of
PE conductor connection, the specification for the leakage current must be ob-
served 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 fixed connection = 1.5 mm

5.4 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.
5.5 Inverter output
5.5.1 Motor connection
The motor leads are connected to the terminals: PE, U, V, W. Several fans can be
connected to the controller-the maximum total current of all motors must not exceed the
current rating for the controller.
Information
•
It is recommended that a separate motor protection unit be foreseen for each fan.
•
For motors with thermistors “TP” (PTC thermistor) e.g. type U-EK230E
•
For motors with thermostats “TB” (thermal contacts) e.g. type STDT16 or AWE-SK (
Enclosure: Circuit suggestion for several motors with motor protection unit type
STDT.)
5.5.2 Disconnection between controller and motor (repair switch)
Ideally, a repair switch should be installed before the controller (supply line discon-
nect).
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.
