4.2 Mains connection
The mains connection is made for 1 ~ types at the terminals: PE, L1, N, for 3 ~ types at
the terminals PE, N, L1, L2, L3 (see connection diagram depending on type). Here, it
must be strictly observed that the mains voltage lies within the allowable tolerance
specifications (see Technical data and nameplate affixed to the side).
The mains voltage must comply with the EN 50160 quality characteristics and the
defined standard voltages in IEC 60038!
4.3 Motor connection
The motor connection is made depending on type (see connection diagram). Several
motors can be connected to the device - the maximum total current of all motors must
not exceed the current rating for the device.
Motor protection via connection of TB thermostatic switches (not suitable for PTC
thermistors). When the thermostatic switches are triggered (motor fault), the device
switches off. Restart is performed once the drive has cooled down either by switching
the mains voltage off and on again (after approx. 2 minutes) or via the switch.
Attention!
If multiple motors are connected, connect thermostatic switches to the TK - TK terminals
in series.
Special function: Automatic restart when motor has cooled down
Automatic restart when motor has cooled down if the both terminals ”J”-”J”are bridged. This special
function is admissible only after consultation with the motor manufacturer and the system operator
must be informed about this.
4.4 Operating indicator contacts for type S-..
KT
Operating indicator contacts, e.g. for shutter control (for contact load, see connection
diagram).
•
Potential-free contacts
– If the device is switched on when mains voltage is applied (step 1 or higher), the
internal relay is energised (=> terminals 11 - 14 bridged).
– In the case of switch-off via the remote control (RT - RT terminals interrupted) and
in the case of motor fault (TK - TK terminals interrupted), the relay is de-energised
(=> terminals 11 - 12 bridged).
•
Contacts to which mains voltage is applied
– The L↓ and N↓ terminals are directly connected to the mains connection, meaning
that there is continuous voltage when mains voltage is applied, even in the switch
position “0”.
– The mains voltage at terminal L' is switched via the internal relay (voltage ON
L'
- L↓ terminals bridged).
