Installation
Requirements
WARNING For protection from electrical shock, do
not
interrupt the power cable ground.
Line Fuse and Line Voltage Selector for the 41501A
Before applying ac line power to the 41501A, verify that the correct line fuse is
installed in the fuse holder and the line voltage selector is set correctly.
WARNING Replace the line fuse only with the same type and rating. Do
not
use repaired
fuses, and do
not
short circuit the fuse holder.
The line voltage selector switch is set at the factory. Verify the voltage selector
setting before applying ac line power to the 41501A. The line voltage selector
switch is located on the rear panel of the 41501A
Ventilation Requirements
The 4155C/4156C has one cooling fan, and the 41501A/B has two 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.
