8.1 Safety Note
When performing electric work on this unit, the local accident
prevention regulations must be followed.
Observe EN 60204-1 (VDE 0113 part 1) to ensure human safety,
integrity of the assets as well as the proper functioning of the unit.
Electric supply lines must be dimensioned for the peak current of the
unit and comply with IEC 227 and IEC 245.
Yellow-and-green coded cords may only be used for connection to
protective earth.
When leading wires through the cable glands on the actuator, their
minimum bending radius has to be considered.
The electric actuators PSQ-AMS are not fitted with an internal electric
isolator, hence a switching device or circuit breaker must be integrated
in the facility. It should be installed close to the actuator and should be
easy to access for the user. It is important to mark the circuit breaker
as this actuator‘s isolator.
Electric installations and over-current protection devices must be
conform to the standard IEC 364-4-41, protective class I resp. DIN IEC
60364-4-44 according to the 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.
8.2 Wiring Arrangements
Depending on order specification, the PSQ-AMS are supplied with two different wiring arrangements.
Wiring to the Main Board: Electric wiring is made to terminals on the main board inside the actuator. Accordingly,
the cover has to be opened for wiring.
Wiring to Terminal Box: Electric wiring is made inside a separate box mounted to the actuator. Take off the cover
from the box and fit the wires to the screwed terminals at the back of the plug modules.
8.3 Electric Wiring
8.3.1 Mains Supply
Isolate the power supply.
Safeguard the line against unauthorized and unintended restarting.
Attention! Observe precautions for handling.
Ground the actuator.
Before opening the cover, touch grounded housing parts.
