4.1 Electrical connection
Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-
fied personnel in compliance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to facilitate
voltage-free work on the electrical equipment. The power supply isolator is not included.
4.1.1 Disclaimer at retrofitting fans
In the case of retrofitting fans in an existing house, regardless of ON/OFF or LPC fans, SKOV recommends that
a local expert is involved in checking the electrical installations. The focus should be on cable dimensions, over-
load protections, local transformers, etc. It is of outmost importance to take the fan specifications into account
and, at the same time, ensure that local requirements are fulfilled.
4.1.2 Mains supply dimensioning regarding harmonic distortion
LPC motor controllers function like any other electronic power converter by converting AC to DC. As this conver-
sion produces a non-sinusoidal current, the mains supply for the motor controller is affected by harmonic distor-
tion.
The electrician or the user of the equipment must ensure, possibly through contact with the supply company,
that the equipment is connected to a properly sized mains supply.
4.1.3 Cabling to connection box and LPC motor controller
Example of cabling to connection box and LPC motor
