2Electrical installation
Electrical installation can only be designed and made by personnel with the appropriate skills and competence.
Ensure all such work is done according to applicable laws and regulations.
1. Loosen the top cover fastening screws.
2. Remove the actuator’s top cover to gain access
to connection terminals.
Fig. 1: Removing top cover.
Make sure fuses are disconnected before the
connection of power supply cables is started.
3. Install the power supply
cables through the cable
glands on the right side and
connect them to the L, N, and
PE/ GND terminals X4
4. Install the control signal
cables through the
cable glands on the left
and connect them in
the X1 communication
connector according to the specification below.
Note: Dual CAN uses a connector with screw
connection.
Fig. 2: Connection terminals location.
2.1 Interface Pinout
The following chapter documents the pinout and placement of the communication terminal X1 for different
communication protocols/interfaces. Modbus, CAN and Dual CAN include an example for hooking up. The terminal is
always placed on the left side of the PCBA. Pin one is the first pin from the left for all interface terminals.

3Maintenance, service and troubleshooting
3.1 Maintenance
The QT2500 is in principle maintenance-free; all bearings and gears are lifetime lubricated and components are
designed to last throughout the actuator’s lifetime. It is however recommended that the actuator is inspected
regularly to reveal any damages caused by mechanical impact, corrosion, etc. The top cover gasket and manual
operation shaft seal should be lubricated with suitable lubricants if they appear to be dry.
3.2 Internal construction
Components are located inside the actuator’s motor and
electronics housing.
Fig. 3: Motor and electronics housing.
Remove the top cover to provide easy access to internals
of the actuator.
