10. Electric Supply
Before connecting to the mains, ensure that the mains supply is isolated and secured
against an accidental switching-on.
Remove the cover of the actuator in order to connect the electric supply (cf. 8, Removing the cover).
The mains connecting cables must be suitably dimensioned to accept the maximum current requirement of the
actuator. The yellow-green coloured cables may only be used for connecting to earth.
When you insert the cable through the drive cable connector, ensure that the max. bending radius for the cable is
observed.
The PSL electric actuators do not have an internal electrical power switch. A switch or power mains switch must be
provided in the building installation. It should be positioned closely to the device and be easily accessible for the user
and shall be labelled as the mains isolator switch for the actuator.
Electric installation as well as over-current and overvoltage protection devices must be conformed to the standard
DIN DIN VDE 0100-410, protective class I resp. protection class 3 (24VAC/24VDC) and also to the standard DIN IEC
60364-4-44 according to the applied overvoltage category of the actuator.
Please protect all of the power supply and control cables in front of the
terminals mechanically by using suitable measures against
unintentional loosening. Never install the power supply and the control
cables together in one line but instead please always use two different
lines.
10.1 Wiring Diagram
Figure 12 indicates the electrical connections for standard actuators. The wiring diagram inside the actuator cover is
binding for the specific actuator connection. See the separate wiring diagram in the corresponding service
instructions for any optional extras.
