SECTION 2
P1350 AC POWER SUPPLY UNPACKING AND INSTALLATION
2.1 UNPACKING
After unpacking the equipment, carefully conduct a thorough inspection of all controls, indicators, and
chassis. If the unit shows signs of shipping damage, do not attempt to operate. File a damage claim
with the responsible carrier. Notify Behlman immediately.
2.2
INSTALLATION
This device is designed to operate on a bench or desk top. It can be mounted in a standard 19 inch
rack cabinet using the RM option.
DO NOT ! ATTEMPT TO MOUNT BY RACK “EARS” ONLY.
Rear
support must be provided. See information for the RM option contained elsewhere in this manual.
It is preferable to operate this equipment in a location which will maintain an air temperature of 0 to
40 degrees C around the ventilation ports. If the unit is to be rack mounted, the enclosure must be
ventilated. The installation should insure that the side and rear vents are unobstructed.
2.3
INPUT POWER REQUIREMENTS
This model is supplied with a standard IEC20 type line cord with an NEMA 15P molded to the line end.
This cord is rated at 15A and will suit most applications. The Model P1350 can operate from a wide
input voltage range but continuous full power operation requires a “stiff” 120V line capable of suppling
at least 20A. The cord should be replaced with an IEC20 plug wired with the desired 20A plug to match
the user’s receptacle. Consult with qualified electrician or Behlman if in doubt.
!
WARNING !
This equipment produces AC leakage current that may exceed dangerous levels
.
This
equipment is supplied with a three-wire AC input that provides for a safety earth connection
to the equipment chassis. For operator safety the chassis of the equipment must be connected
to the installation site safety earth. The safety earth connection also provides a return path for
leakage currents associated with the equipment’s internal line filter. Leaving this connection
floating may create a shock hazard and/or electromagnetic interference
.
IMPORTANT NOTE:
The output of the power supply is floating and also provides a safety earth connection. It is permissible
to tie one side of the output to the safety earth. This will allow the power supply to conform to section
250 of the National Electrical Code (NEC). Consultation with a qualified electrician is recommended
for permanent installations in buildings or vehicles.
This equipment is designed to be operated in a dry indoor location. Do not operate in the presence of
rain or other moisture.
