DEH40632
AN 12-1007, Rev.03, 04/04/2012
The environments for NEMA Type 1 enclosures shall be indoor where the
following condition may exist; falling dirt.
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 Redundant Drive 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 input and output power 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 to prevent
metal shavings or chips from landing on part or electronic boards.
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.
