ANYTHING
that will interfere with access to equipment or specification labels .
The required voltage is written on the specification label .
Follow the wiring diagram that came with the equipment .
The wiring to be carried out on site by a qualified electrician is indicated by dotted lines on the wiring
diagram. Solid lines indicate factory-made wiring.
3.5. INSTALLATION OF AIR INLET/OUTLET COVERS (IF REQUIRED)
Air inlet/outlet covers can be delivered separately from the unit, in some cases, to save space during shipping.
They are designed in a simple way so that they screw onto the outer wall and their location is clearly indicated
by the holes previously made.
Step 1
: Position the air covers on their support .
Step 2 : Screw the air covers all over the contour with self-drilling screws (supplied by Nagas).
Step 3: Seal the entire perimeter of air covers with sealant to avoid openings between the entrance cover and
the outer wall of the unit and thus the risk of intrusion of rain or snow .
3.6. INSTALLATION OF AIR INLET/OUTLET COVERS (IF REQUIRED)
Electrical connections inside the unit are made at the factory before the unit is shipped. The contractor at the
site must take care of making the connections of the general power supply and remote control (if required).
Several connection strategies are possible depending on the type and size of cabling used. It is therefore
important to follow the indications given on the electrical diagram that is attached to the unit in the control
panel. Refer to the nameplate to know the specific voltages and amperages of the unit.
The unit must be electrically grounded, and all wiring must be installed by a qualified electrician in accordance
with the National Electrical Code (ANSI/NFPA-70) and/or the Canadian Electrical Code (CSA 22.1) and the
approval of the competent authorities.
On-site wiring diagrams and internal wiring diagrams are included in the control panel. Power requirements are
indicated on the specification label.
