Wiring Procedure:
The wiring diagram (incl. cabling) and Installation, Commissioning and
Operating Instructions are included in the accompanying documenta-
tion of the control unit; it is also necessary to use the AeroMaster XP
Installation, Commissioning and Operating Instructions.
General Procedures for Wiring:
 Connect power elements.
 Connect M&C elements.

Check the installation of the air-conditioning unit
(if delivered).
 Connect the air-conditioning unit heater section
(see Accessories).
 Lead the main power supply (cable harness dimensioned for the
total input current of the air-handling unit) to the main switch
terminal box on the section panel.
 Check the completed wiring.
 Check the tightening of the cable grommets, and blind those
unused.
 Perform the electrical equipment initial inspection.
Note:
To mount the cables and wiring harness inside the section, use the
rubber grommets installed in the openings of the assembly supporting
profile to avoid damage to the cable insulation, see figure # 29.
Safety
 When performing any work, repairs or maintenance, the device
must always be disconnected from the power supply.
 When planning or installing the air-handling unit, observe norma-
tive requirements for safe access to the air-handling unit.
 When reinstalling the covers (front or side covers) also restore
their conductive connections (properly tighten the screws using
fan washers).
 Maintain the prescribed degree of protection.
Maintenance

XPRJ/XPRF sections do not require any special maintenance if
installed in the intended environment.
 Any damage to the surface protecting galvanized layer (zinc 275
g/m 2 ) must be repaired immediately with priming paint (S2013) to
avoid corrosion.
 Depending on the operating conditions, regularly check the filter
inserts of the chamber inner ventilating apertures
