UNPACKING AND INSPECTION
Your Model 1178 was carefully packed at the factory, and
the container was
designed
to
protect
the unit from rough handling.
Nevertheless, we recommend careful examination of the shipping
carton
and its
contents
for any
sign of physical damage which could
have occurred
in transit.
If
damage
is
evident, do not
destroy any
of the packing mater-
ial or the carton, and
immediately notify the carrier
of
a
possible
claim
for
damage.
Shipping claims must be made by the consignee.
The shipment should include:
Model 1178 Dual Peak Limiter
UREI Instruction Manual
(this book)
Two-part Warranty Card bearing the
same serial number
as
the Model 1178.
Rack mounting hardware.
2.2
ENVIRONMENTAL CONSIDERATIONS
The system will operate satisfactorily over
a
range of ambient
temperatures from 0*C
to
+50-0 (+32*F
to 122*F), and
up
to 80% non-
condensing relative humidity.
If
the system
is
installed
in an
equipment rack with high heat
producing equipment (such
as
power
euntiplifiers
)
,
adequate ventilation
should be provided
in order to
assure longest component life.
Also,
while circuitry susceptible
to
hum pick-up
is
sufficiently shielded
from moderate electromagnetic fields, installation should be planned
to avoid
mounting the system immediately adjacent
to large
power
tr ans
formers
,
motors
,
etc
.
2.3
POWERING
The 1178 may be operated from either
100
-
125
VAC
or 200
-
250
VAC mains
(50
Hz or 60
Hz,
single phase.)
As
indicated
in
Section
2.4,
the nominal line voltage may be selected with
a
rear
panel switch. BE SURE TO
VERIFY BOTH
THE ACTUAL LINE VOLTAGE, AND
THE SETTING OF THE VOLTAGE SELECTOR SWITCH BEFORE CONNECTING
THE 1178 TO THE MAINS.
