4.5. Electric connection
Electric connection of AHU should be carried out by the qualified personnel and should be done in accordance
with all standards and regulations being in force in the country where the unit is installed. The cross-section
and type of cables (e.g. a shielded cable) feeding individual functional segments should be selected basing on
nominal current and specific operation conditions (e.g. ambient temperature, way of cabling, distance from the
power supply).
Before switching on the power supply, check conformity of voltage and frequency of a supply network with the
data shown on the device's rating plate. The permissible fluctuation of the supply voltage and its frequency to the
values shown on the rating plate is ±5%. If a discrepancy exists, the device must not be connected.
4.6. Fan sets
Fan sets can be supplied with AC or EC motor, depend on the choose option and AHU selection.
Fans' motors are adapted to operate in a dusty and humid environment and their insulation (F-class) is adapted
to cooperate with the frequency converter. No additional means inuring the motor against conditions of the AHU
fans' section are required.

Attention: before connecting the fan set one should check carefully the rated parameters of
both power supply and the converter’s output.
One should connect the fan set by means of fault protection appropriate for the applied frequency converter. In
case of powering with the use of a frequency converter it is not necessary to connect the motor’s PTC protection.
Overload protection is covered by the frequency converter by means of activating specified parameters and
introducing the motor’s rated data in accordance with the manual provided together with the frequency converter.

- Connection of coolers should be done in such a way so as not to allow for stresses exchanger s connections which may result in mechanical damages or leakages the pipeline weight and thermal stresses cannot be passed onto the exchanger s connections depending on local conditions please use the compensation at the inlet and outlet of the pipeline system in order to level the pipeline s linear expansion during assembly of the supply system to the cooler equipped with the screwed connections counter the exchanger s connection with additional wrench fig 10
- Examples of connecting inlet and outlet pipelines for various ahu versions shown in the picture 10
- Fig securing the screwed connections of the exchanger 10
- Inlet and outlet exchanger s connections should be connected so that the exchanger operates in a counter current way streamwise operation results in the lower average discrepancy of temperatures which influences the exchanger s performance 10
- Table 2 diameters of coolers connection pipes 10
- The supply system should be planned in such a way so that it does not collide with the other ahu sections the way of connecting the exchangers with the supply system should allow for an easy pipeline disassembly in order 10
