4. ACTUATOR
4.1 Types of power supply
The Fast actuators can be supplied with mains power ranging 230VAC (50Hz) (with a tolerance of ±10%), with a
three-core supply cable: BLUE, neutral common; BLACK, open phase; BROWN, closed phase.
4.2 Calculation of the force necessary
F = Force required to open in kg (kilogrammes)
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)
4.3 Pack and tools required for assembling the actuator
The actuator is packed individually in a cardboard box. Each pack contains:
Electric actuator, 230V ~ 50Hz, with electric supply cable, support brackets, fixing bracket for top-hung window,
fixing bracket for bottom-hung window 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.
