Instructions for Bench Use
The unit is supplied with all the hardware required for bench use and special instructions for use in this
manner are not necessary. However, before connecting the unit to the local power source, verify that the
power cord is equipped with a three-terminal connector (see the Safety Precautions of paragraph 1-6).
1-5. Rack
Mounting
Optional brackets are available for mounting the Model 4300B (4350ATE) in a standard 19" equipment rack.
These are listed in Section 3. The size of the unit and the location of its center of gravity dictate that it must be
supported on both sides along its entire length through the use of trays or slides. If it is to be transported while
mounted in a rack, it should be supported so as to prevent upward or downward movement.
It is recommended that blank panels at least 1.75 inches high be installed between this and any other units in
the rack to ensure freedom of air flow. Under no circumstances should the ambient air temperature around the
unit exceed 50
°
C while the unit is in operation or 70
°
C when power is removed.
1-6. Safety
Precautions
The power plug must be a three-contact device and should be inserted only into a three-contact mating socket
where the third contact provides a ground connection. If power is provided through an extension cable, the
ground connection must be continuous.
Any discontinuity in the ground lead may render the unit unsafe
for use!
The Model 4300B (4350ATE) employs forced air cooling of the internal components. This operates
continuously and care must be taken to ensure that the intake and exhaust ports remain clear.
Blocked vents
may cause a dangerous overheating condition!
