2.5.1 MACHINE POWER SUPPLY
Use a multipole conductor with protective sheath. The cable section depends on the
maximum absorbed current of the machine (A) as shown in the dedicated wiring diagram.
For the entry of the power cables in the machine use the holes provided at the base by the
Manufacturer (UNDER/OVER version).
Fix the cables to the internal machine riser using cable ties. Do not touch hot or sharp
surfaces.
Connect the power cable to the terminals of the door locking switch and to the ground
terminal.
The power cable must not be placed into the machine cable ducts.
The electrical panel is always positioned in the upper section of the machine
as shown in the figures.

2.5.2 AUXILIARY ELECTRIC CONNECTIONS
The control circuit is shunted off the power circuit from inside the switchboard.
The auxiliary connections can be found in the terminal board contained in the electrical
panel of the machine.
Connections required:
• PAC-IF connection to the Mr.Slim condensing unit. Below are the cable
characteristics
o cable: shielded
o number of pairs: two
o cable section: min. 0.3 mm2
o maximum permitted length: 120 m
•
External enable (for all series - contact powered)
• Generic Alarm 1 and Generic Alarm 2 (for all series - deviated contact free from
voltage)
•
Fire-smoke alarm (for all series)
•
Leak detector alarm
It is recommended that any auxiliary connection cables are separate from power cables.
Otherwise, screened cables should be used.
2.6 AIR CONNECTIONS
The sizing of the ducts must be defined during the system design stage.
INFORMATION
For the size F3 Over, allow for a channel that can be frontally
inspected at the top, should it become necessary to handle (remove)
the air treatment centrifugal fan.

Air delivery duct (not supplied).
Fix the air delivery duct to the anti-
vibration joint as shown in the figure
(fastening system not supplied).
Interpose a gasket as shown in the figure
(not supplied)
Anti-vibration joint (not supplied).
The anti-vibration joint prevents the
transmission of vibrations to the ducts.
Upper machine frame.
Secure the anti-vibration
joint to the machine frame
using self-tapping screws
as shown in the figure.
Interpose a gasket as
shown in the figure (not
supplied).
2.6.2
The useful nominal and maximum static pressure values of the machine are
indicated in the relevant Technical Bulletin.
Pressure drops in the ducts must be minimal; high values will cause an increase in
electricity consumption of the fans.
