Power connection
The power connection of the fans consists in connecting them to the 230 VAC via their control unit. The fans must be
connected directly to an electrical box and never to an end-used plug.
Each fan has its own power supply. The operation consists in connecting the 230 VAC mains to each unit.
Switch - main circuit-breaker: It is recommended to have a general switch
–
circuit breaker upstream
of the set of personal protective devices. Make sure it is open (no power) during the installation
phase.
Reminder: Protection of the power supply circuit of each fan must be provided in the device, in the
form of a fuse or circuit-breaker (thermal, current overload, or similar) in conformity with standard
EN60335-1. Recommended fuse = 16A max.
It is recommanded to use a differential circuit breaker of 300
mA for a group of 10 fans.
The cable used must have 3 conductors, be between Ø6 mm and Ø12 mm, comply with the
installation standards in force (colour code in particular), have conductors with a cross section of at
least 1.5 mm², and be able to withstand the environment in which it is installed (, be resistant to UV).
A manual circuit-breaker must be placed on the mains upstream of the control unit. Make sure that it
is in fact open (no power) during the installation work. This must be visible and accessible from any
connected fan. It can be common to several fans or individual depending on the configuration, the
goal is to allow quick and easy manual shutdown in case of problems or accidents.
To make the VBP+ F400 compliant, every electrical cable that can be in contact with the plenum
must be resistant for a temperature of 400°C.
