1. General
Bus contacts.
Terminal
blocks
The cable adapter, 32611101, is used for connecting together
a supply air handling unit and an extract air handling unit that
are controlled by common control unit installed in one of the
air handling units. “IQnomic” can be read on the identification
plate of the air handling unit with control unit.
2. Installation
One cable adapter is fitted inside the electrical equipment cubicle of the GOLD air handling unit without control unit and one
unmounted cable adapter is supplied inside the unit.
The unmounted adapter must be fitted in the same way inside
the electrical equipment cubicle of the GOLD air handling unit
with control unit. See Fig. 1. Connect the bus cable (Part No.
32249801), included in the supply, between the bus contact on
the control unit and the cable adapter.
Connect the cable between the supply air and the extract air
handling units from terminal to terminal, i.e. from Terminal No. 1
in the supply air handling unit to Terminal No. 1 in the extract air
handling unit. See Fig. 2. Use one of the holes in the oval rubbercovered cable glands on the inspection sides of the air handling
unit, for leading the cable into the control unit.
The cable between air handling units is not included in the
supply.
A twisted-pair cable is recommended. Use one twisted-pair cable
for 24 V and another twisted-pair cable for bus communication.
