The actual commissioning and setting of the basic parameters of the controller must be performed by an authorized company with authorization
and training from S&P UK Ventilation Systems
Ltd
.
The cables must be secured outside the unit against being pulled out in the installed bushings.
The cable routes of safe and mains voltage must be separated due to electromagnetic compatibility requirements. It is necessary to build 2 cable
routes at a distance of at least 20
–30 cm from each other, if possible with a minimum of crossing. A grounded metal partition in the entire height
of the metal grounded gutter is also permissible.
If the main supply has a conductor cross-section of less than 6 mm
2
, we recommend connecting the controller to the earthing system with a
copper conductor with a cross-section of at least 6 mm2 due to the impedance of the earth conductor for high-frequency interference. We
recommend to fit the power supply with surge protectors.
It is necessary to check the function of all connected elements, especially emergency inputs, the direction of rotation of the fans, the correct
phasing of the damper actuators and mixing valves. If the unit is equipped with a Digireg
®
control system directly from the factory, a SETPACK
test package has been performed on the unit. SETPACK covers basic settings of control system parameters and testing of all peripherals.
