(1) Connection capacities actually available for each machine, dened according to the connection terminal size, the control box access opening size and the available
space inside the control box.
(2) Selection simultation result considering the hypothesis indicated.
(3) If the maximum calculated section is for an XLPE cable type or specied “not compatible”, this means that it exists a risk to exceed the real connection capacity available.
Special attention must be given to the selection.
Note: The currents considered are given for a machine equipped with a hydronic kit operating at maximum current.
5.5 - Power cable entry
The power cables can enter the unit control box from above the
unit. A removable aluminium plate on the upper part of the control
box face allows introduction of the cables. Refer to the certied
dimensional drawing for the unit.
The plate xing on the electrical box as well as the cable passage
through the plate have to be tight.
If not, the differential pressure sensor should not detect the
electrical box fan operating. This will prevent the unit from starting.
5.6 - Field control wiring
IMPORTANT: Field connection of interface circuits may lead
to safety risks: any control box modication must maintain
equipment conformity with local regulations. Precautions
must be taken to prevent accidental electrical contact between
circuits supplied by different sources:
The routing selection and/or conductor insulation
characteristics must ensure dual electric insulation.
In case of accidental disconnection, conductor xing between
different conductors and/or in the control box prevents any
contact between the conductor ends and an active energised
part.
Refer to the Touch Pilot Control manual and the certied wiring
diagram supplied with the unit for the eld control wiring of the
following features:
• Customer interlock
• Remote on/off switch
• Demand limit external switch
• Remote dual set point
• Alarm, alert and operation report
• Evaporator pump control
• Heat reclaim condenser pump control (option)
• Hot water valve control (option)
• Various interlocks on the Energy Management Module
(EMM) board (accessory or option)
CCN bus connection
• The permanent connection to the system CCN bus is made
at the terminal provided for this purpose inside the control
box.
• The connection of the CCN service tool is possible at a
socket under the control box, accessible from outside.
All panel feedthrough of control cables have to be tight to allow
electrical box fan operating detection.
5.7 - 24 V power reserve for the user
Control circuit reserve:
After all required options have been connected, the TC transformer
includes a power reserve that can be used for the eld control
wiring: 2 A (24 V a.c.) or 48 VA.
