6.3.3 INSTALLATION
IP20 protection controllers are designed for installation in an indoor dry environment without aggressive chemicals in normal areas according
to ČSN 33 2000-3, ambient temperature up to 30 °C. The short-circuit resistance of the Digireg
®
switchboard is 6 kA.
Distribution board
protection is IP20 or IP65 and the material is listed
below in the catalog sheets at www.solerpalau.co.uk
.
Cross-sections of power cables (fans, pumps
, electric heaters…) must be designed according to specific installation conditions in accordance
with ČSN 33 2000-5-52 ed.2.
The installation must be carried out by an authorized person working on electrical equipment in accordance with legal requirements and
familiar with the function of the individual
components of air conditioning and control. Observe the valid ČSN during installation.
An initial
inspection must be performed before commissioning.
For the assembly and installation of air conditioning, an authorized project of air
conditioning and M&R is required, which solves both the air outputs and the piping system, as well as the electrical connection of elements
and operating modes.
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 mm
2
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.
!
For heat recovery units supplied with a free located Digireg
®
control box, which is not fixed to
the unit wall, the firm housing must be ensured of harness between the unit and control box in
the firm cable line (such as cable trays, cable bench etc.). The harness between the unit and
the control box shall not be freely suspended or positioned on the floor!!! After firm laying of the
harness it is possible to start the works on connection of individual wires to the Digireg
®
control box.
!
CAUTION!
Digireg
®
distribution boards are not
designed for direct installation to the
flammable material!
