2.1
Initial
Inspection
Inspect
the
package
exterior
for
evidence
of
damage
due
to
handling
in
transit.
Notify
the
carrier
and
Spellman
immediately
if
damage
is
evident.
Do
not
destroy
or
discard
any
of
the
packing
material
used
in
a
damaged
shipment.
After
unpacking,
inspect
the
panel
and
chassis
for
visible
damage.
Standard
Spellman
EVA
high
voltage
power
supplies
are
covered
by
a
warranty.
Custom
and
special
order
models
(with
an
X
suffix
in
the
model
number)
are
also
covered
by
a
warranty.
Check
the
specific
warranty
terms
by
referring
to
the
Warranty
document
contained
in
this
operator’s
manual.
2.2
Input
Requirements
For
proper
protection
of
the
EVA
power
supply
a
circuit
breaker
protected,
dedicated
electrical
service
must
be
provided
for
each
EVA
chassis.
EVA
units
are
not
phase
dependent;
the
three
AC
input
phase
connections
can
be
orientated
in
any
manner
with
no
adverse
effect
on
power
supply
performance.
See
Table
2.1
2.3
Mechanical
Installation
Units
in
the
EVA
series
have
front
panel
holes
for
standard
EIA
rack
mounting.
The
rack
must
allow
rear
access
for
cable
connections.
Units
are
fully
enclosed
and
are
suitable
for
bench
or
tabletop
operation.
It
is
strongly
recommended
to
support
the
chassis
by
guides
or
shelves.
2.4
Airflow
Requirements
EVA
units
(3/6/12kW)
are
forced
air
cooled,
air
enters
the
chassis
via
openings
on
the
right
and
left
side
panels
and
air
is
forcibly
exhausted
out
the
rear
panel
via
a
single
fan.
Whatever
mechanical
installation
is
implemented
airflow
into
and
out
of
the
unit
must
not
be
compromised.
Additionally
it
is
the
responsibility
of
the
user
to
assure
that
air
entering
the
unit
is
not
above
the
maximum
ambient
temperature
of
40°C.
Airflow
volume
is
100cfm
for
3/6kW
units
and
300cfm
for
12kW
units.
