Field control wiring
IMPORTANT: Field connection of interface circuits may lead
to safety risks: Any control box modification 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 fixing
between different conductors and/or in the control box
prevents any contact between the conductor ends and
an active energised part.
Refer to the SmartVu
TM
control manual and the certified wiring
diagram supplied with the unit for the field control wiring of the
following features:
-
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)
-Set point reset via outside air temperature sensor reset
-Various interlocks on the Energy ManagementModule (EMM)
board (option).

(1) Connection capacities actually available for each machine. These are defined according to the connection terminal size, the electrical/control box access opening
dimensions and the available space inside the electrical/control box.
(2) Selection simulation result considering the hypotheses indicated.
(3) If the maximum calculated section is for an 90°C cable type, this means that a selection based on a 70°C cable type can exceed the connection capacity actually
available. Special attention must be given to selection.
The protection against direct contact at the electrical connection point is compatible with the addition of terminals extension. The installer must determine whether these
are necessary based on the cable sizing calculation.
NOTE:
The currents considered are given for a machine equipped with an hydraulic module operating at maximum current.
