GENERAL WIRING INSTRUCTIONS
WARNING The wiring technician must be trained and experienced with
electronic circuits. Disconnect power supply before attempting any
wiring connections or changes. Make all connections in accordance with
wiring diagrams and follow all applicable local and national codes.
Provide disconnect and overload protection as required. Use copper,
twisted pair, conductors only. If using electrical conduit, the attachment
to the actuator must be made with flexible conduit.
Always read the controller manufacturer's installation literature
carefully before making any connections. Follow all instructions in this
literature. If you have any questions, contact the controller manufacturer
and/or Belimo.
Transformer(s)
Belimo actuators require a 24 VAC class 2 transformer and draws a
maximum of 10 VA per actuator. The actuator enclosure cannot be opened
in the field, there are no parts or components to be replaced or repaired.
– EMC directive: 89/336/EEC
– Software class A: Mode of operation type 1
– Low voltage directive: 73/23/EEC
CAUTION It is good practice to power electronic or digital controllers
from a separate power transformer than that used for actuators or other
end devices. The power supply design in our actuators and other end
devices use half wave rectification. Some controllers use full wave
rectification. When these two different types of power supplies are
connected to the same power transformer and the DC commons are
connected together, a short circuit is created across one of the diodes in
the full wave power supply, damaging the controller. Only use a single
power transformer to power the controller and actuator if you know the
controller power supply uses half wave rectification.
