Line Fuse; Power Cord; Instrument Cooling - Tektronix 2205 Operator's Manual

Preparation for Use
LINE FUSE
The fuse holder is located on the rear panel and contains the line
(mains) fuse. Use the following procedure to verify that the
proper fuse is installed or to install a replacement fuse.
1. Unplug the power cord from the power source (if applica¬
ble) .
2. Use a screwdriver to press in and slightly rotate the fuse-
holder cap counterclockwise to release it.
3. Pull the cap (with the fuse) out of the fuse holder.
4. Verify that the fuse is the same type listed on the back of the
instrument. The two type of fuses listed are not directly in¬
terchangeable; they require different types of fuse caps.
5. Reinstall the fuse (or replacement fuse) in the fuse-holder
cap.
6. Replace the fuse holder and cap.
POWER CORD
This instrument has a detachable, three-wire power cord with a
three-contact plug for connection to both the power source and
protective ground. The ground contact on the plug connects
through the power-cord to the external metal parts of the instru¬
ment. For electrical shock protection, insert this plug only into a
power source outlet that has a properly grounded protective-
ground contact.
Instruments are shipped with the required power cord as or¬
dered by the customer. Power cord plug information is pre¬
sented in Table 1-1, and part numbers are listed in Table 6-1.
INSTRUMENT COOLING
Maintain adequate airflow to prevent instrument damage from
internally generated heat. Before turning on the power, check
that the spaces around the air-intake holes on the sides of the
cabinet are free of any obstruction to airflow.
