The environments for NEMA Type 1 enclosures shall be indoor where the following
condition may exist; falling dirt.
The environments for NEMA type 12 enclosures shall be located indoors where the
following conditions may exist; dust, falling dirt, and/or non-corrosive dripping liquids.
The environments for NEMA Type 3R enclosures shall be indoor or outdoor where the
following conditions may exist; falling dirt, rain, sleet and snow and undamaged by the
external formation of ice on the enclosures. It is recommended that outdoor enclosures
should not be mounted in direct sun light to avoid tripping over temperature & possible
damage to equipment.
For all enclosure types the ambient temperature must remain in the range from -10
C
(14
F) to 40
C (104
F). Never store or operate panel below or above ambient range.
All wall-mounted enclosures must be mounted on a non-flammable or heat resistant
surface.
Some enclosure configurations of AF-600 FP Panels require ventilation to keep the
components and inverter within their thermal recommendations. The enclosure door
and sides contains grilles at the bottom and top to allow for air to circulate through the
enclosure. Ventilation is accomplished by the cooling fan(s) mounted at the bottom
grille(s) pulling air into the enclosure and forcing it out the top grille(s).
The air used for ventilating the enclosure must be free from condensation, moisture,
dirt, dust, and flammable or combustible vapors and/or dust.
The recirculation of air leaving the enclosure should be avoided. Air forced out of the
enclosure should not be allowed to circulate back into the enclosure. All enclosures
shall be installed where the doors are able to completely open. Do not mount
enclosure where the air flow into or out of it may be restricted.
INSTALLATION
Panels must be installed per NEC 110.26 and local codes and have minimum clearance
to operate door safely and allow for proper maintenance as needed, (e.g., access and
change filters).
Determine conduit entry and exit locations on the enclosure before mounting. See the
appropriate
Outline
drawing for recommended conduit locations.
Allow for power in and power out wiring to be located in separate conduit.
No conduit holes are provided in the enclosure; therefore the customer must install all
conduit holes. Place a protective covering over the components of the panel while
installing the conduit holes.

CAUTION:
Damage to equipment will result if panel is operated or stored below or
above stated ambient temperature range.
.
WARNING: The temperature of the inverter heat sink fins may reach 90
C (194
F).
Thus if not mounted on a heat resistant or a non-flammable surface a fire may
occur resulting in a fatal or serious injury, as well as damage to equipment.
