At heating coils:
-
Control-technological frost protection: Installation of a thermostat on the air outlet side to trigger
alarm or temperature variation alert. (Setting trigger temperature 5 °C). In the event of an
alarm, the mixture valve opens (100%), the heating circuit pump gets a signal and the fan is
switched off automatically.
At run-around-systems:
-
Usage of water/glycol fluid mixtures with adequate glycol concentration. Performance loss must
be considered.
7 Electrical connection
-
The electrical connection must be executed in compliance with international regulations such
as the Low Voltage Directive 2014/35/EU and the requirements of electromagnetic compatibil-
ity Directive 2014/30/EU, of national legislation and the requirements of the local electricity pro-
vider.
-
All electrical connections must be inspected annually and deficiencies (for example, loose ca-
ble strands, loose screw and clamp connection, etc.) must be eliminated and repaired immedi-
ately.
-
For systems, which operate in hazardous areas, there are special provisions for component /
equipment design and used materials. For details refer to
chapter 11 (AHUs)
.
7.1 Connecting to an external protective conductor system
The AHU must be connected to an external protective conductor system. The AHU shall be either:
-
connected at the base frames or
-
alternatively, at the Potential Compensation, that is mounted on the flexible connection by EU-
ROCLIMA.
Furthermore, each electrical component must be connected to the protective conductor system.
The connection to the external protective earth system has to be executed according to EN 60204-
1, pt. 5.2. The minimum cross-sectional-surface of the earth at frequency converter has to be
10 mm², otherwise 4 mm² at AHUs with control. Depending on the cross-sectional-surface of the
outer conductor, the requirements regarding minimum cross-sectional-surfaces of the protective
earth system according to EN 60204-1, pt. 5.2, table 1 have to be considered additionally.
After assembling and installation the consistency of the protective conductor system has to be
checked and documented according to EN 60201-1, pt. 18.2.
Lightning protection for roof AHUs
WARNING!
A lightning protection, especially for roof AHUs, must be professionally installed
on site according to national rules and guidance. Otherwise, a fire can be caused,
for example, by a lightning strike.
7.2 AC motors
The three-phase motors fulfill the following criteria:
-
Protection class: IP 55
-
Thermal class: F
-
Type: B3
