Wall Mounting
Mounting to a plywood backboard or studs:
1.
On each side remove the four screws in the corners and use them to
attach the mounting flanges so that the flanges are facing the rear of the
unit.
2. Hold the unit level against the surface to which it will be mounted.
3. Using the keyholes,mark on the mounting surface where the mounting
screws (not included) should be positioned.
4. Set the unit aside and install the screws leaving about
1
/4" of the screws
sticking out of the surface.
5. Slip the unit over the screws through the keyholes and let the unit rest
on the screws.Tighten screws snugly.
Rack Mounting, Flush
Mounting flush to a rack:
1. On each side remove the four screws in the corners and use them to
attach the mounting flanges so that the flanges are facing the front of
the unit.
2. Attach unit to rack with 4 rack screws (not supplied). Do not use
keyholes for mounting to a rack.
Rack Mounting, Recessed for Wire Access
Recessed in a rack to allow for top or bottom wire entry:
1. On each side remove the four screws in the corners and use them to
mount the mounting flanges so that the flanges are protruded from the
front of the unit.This recess allows enough space for wire access from
top or bottom.
2. Attach unit to rack with 4 rack screws (not supplied). Do not use
keyholes for mounting to a rack.
Rack Mounting Considerations
If installed in a closed or m
ulti-unit rack assembl
y
,
the operating ambient
temperature of the rack environment may be greater than room ambient.
Ther
ef
or
e, consideration should be given to installing the equipment in an
en
vir
onment compatible with the man
ufactur
er’s maximum rated ambient
temperature (Tmra). Maximum recommended ambient temperature for the
UTI3
12 is 40º C and 104º F
.
Installation of the equipment in a rack should be such that the amount of air
flo
w r
equir
ed f
or safe operation of the equipment is not compromised.
Circuit overloading consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of circuits
might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when
addressing this concern.
Reliable ear
thing of rack-mounted equipment should be maintained.
Par
ticular
attention should be given to supply connections other than direct
connections to the branch circuit (e.g., use of power strips).
