INITIAL INSPECTION
NOTE
2-2 Before shipment, this instrument was inspected
and found to be free of mechanical and electrical de¬
fects. As soon as the instrument Is unpacked, inspect
for any damage that may have occurred in transit. Save
all packing materials until the inspection is completed.
If damage is found, a claim should be filed with the
carrier immediately. Also, a Hewlett-Packard Sales and
Service office should be notified.
2-3 i\flechanica! Check
2-4 This check should confirm that there are no
broken connectors and that the panel surfaces are free
of dents and scratches.
2-5 Electrical Check
2-6 The instrument should be checked against its
electrical specifications. Section V includes an "in-cab-
inet” performance check to verify proper instrument
operation,
2-7. INSTALLATION DATA
2-8 The instrument is shipped ready for bench oper¬
ation. It is necessary only to connect the instrument to
a source of power and it is ready for operation.
2-9 Location
2-10 This instrument is air cooled. Sufficient space
should be allotted so that a free flow of cooling air can
reach the instrument when it is in operation. At least
1/2-inch clearance at the bottom of the unit is recom¬
mended to permit proper air flow. The supply should
be used in an area where the ambient temperature does
not exceed 50°C. If operated at an ambient greater than
50°C, the supply's output current must be linearly de¬
rated down to 50% at 71°C.
If the power supply must be operated in
a restricted air flow environment, the supply's
power consumption (and heat dissipation
requirements) can be minimized by oper¬
ating at low tine input voltage. Consult your
nearest HP sales engineer for more infor¬
mation on the cooling requirements for
your specific operation
2-11 Mounting Orientation
2-12 Figure 2-1 shows outline and dimension infor¬
mation for each modular power supply size. As shown,
holes are provided on three surfaces of the supplies any
of which can be used to install the supply in the up¬
right position. If the top mounting holes are used; how¬
ever. be sure that a rigid top support is employed to
support the weight of the unit{s). Note that if any other
orientation other than upright is required, adequate air
flow must be provided; see your nearest HP sales engi¬
neer for additional information.
2-13 Rack Mounting
2-14 The modular power supplies can be readily
mounted in any combination in a standard 19-inch
rack using the Hewlett-Packard Rack Mounting Tray,
Model 62410A. The supplies are mounted upright and
attached to the tray using the two (A— suffix models)
or four {C— and E— suffix models) 10-32 threaded
mounting holes located in the bottom of the supply
case. The maximum number of supplies that can be
mounted in the tray depends on the types of supplies
used. For example, if all 1/8-width {A- suffix) supplies
are employed, eight modular power supplies can be
mounted in the tray. Of course, the tray does not have
to be filled to capacity.
