Installation
Requirements
Ventilation Requirements
The B1500A has cooling fans. To ensure adequate airflow, make sure that there is
sufficient clearance around the cooling fans: 6 inches (150 mm) behind, 3 inches (70
mm) on the sides, and 0.5 inch (12 mm) above and below.
If the airflow is restricted, the internal operating temperature will
be higher. This
may reduce the instrument's reliability, or cause the thermal-protection circuits to
turn the instrument off.
Power Cable
CAUTION Before applying AC line power to the B1500A, ensure that the correct power cable
is used.
In accordance with international safety standards, this instrument is equipped with a
three-prong power cable. When connected to an appropriate AC power outlet, this
cable grounds the instrument frame. The type of power cable shipped with each
instrument depends on the country of destination. Refer to the following table for
Agilent part numbers of the power cables available.
If the plug on the cable does not fit the power outlet, or the cable is to be attached to
a terminal block, cut
the cable at the plug end and re-wire it. This work should be
performed by a qualified electrician, observing all local electrical codes.
The color coding used in the cable will depend o
n the cable supplied. If a new plug
is to be connected, it must meet local safety requirements and include the following
features:
adequate load-carrying capacity (see “Specifications” on page 2-33.)
ground connection
cable clamp
WARNING For protection from electrical shock, do not interrupt the power cable ground.
