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.

100/120 Vac UL/CSA T 8A, 250 Vac
220/240 Vac UL/CSA T 4A, 250 Vac
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.
