4. ACTUATOR
4.1 Types of power supply
The Liwin series of actuators is available in various models and colours in two electrical supply versions:
• 230 Vac - can be supplied with mains power 230 Vac (50 Hz) (with a tolerance of ±10%), with a three-core
supply cable: BLUE, neutral common; BLACK, open phase; BROWN, closed phase.
• 24 Vdc - can be supplied with a voltage of 24 Vdc with a two-core supply cable: BLUE, connected to the +
(positive) closed; BROWN, connected to the + (positive) open.
4.2 Calculation of the force necessary
The calculation is made without considering the loads due to atmospheric agents.
Key to symbols F = Force required to open in N (Newton)
P = Weight of the window (only moveable part) in kg (kilogrammes)
C = Opening travel of actuator in cm (centimetres)
H = Height of the openable part of the window in cm (centimetres)

F = [(P / 2 ) x (C/H)] x 9.8
For all the W-net systems the total push force of the syncronized actuator con be calculated by creating a sum
of the force of every single actuator and the subtracting 30% of the force remaining.
4.3 Pack and tools required for assembling the actuator
The actuator is packed individually in a cardboard box. Each pack contains: electric actuator, 230 Vac 50 Hz
or 24 Vdc, with electric supply cable, support brackets, fixing bracket for top-hung window, fixing bracket
for bottom-hung window, drilling template and instruction manual. Before starting to fit the actuator, we
recommend preparing the following fitting materials, tools and equipment: Metre rule or tape measure,
pencil, drill/screwdriver, set of drill bits for metal or wood, set of screw bits, electrical pliers, screwdrivers,
screws and/or threaded inserts suitable for the type of window material. AVOID using self-tapping screws
and/or three-lobed screws on any metal windows.
