General Information

Safety and Preparation for Use

Dangerous voltages, capable of causing injury or death, are

WARNING present in this instrument. Do not remove the product covers

or panels. Do not apply power or operate the product without

all covers and panels in place.

AC line voltage

The DC205 Precision DC Voltage Source operates from a 100 V, 120 V,

220 V–230 V, or 240 V nominal ac power source having a line fre-

quency of 50 Hz or 60 Hz. Before connecting the power cord to a

power source, verify that the LINE VOLTAGE SELECTOR, located

in the rear panel power-entry module, is set so that the correct ac line

voltage value is visible. For operation with 230 V ac power, the LINE

VOLTAGE SELECTOR should be set to 220 V.

The DC205 Precision DC Voltage Source will be damaged if oper-

CAUTION ated with the LINE VOLTAGE SELECTOR set for the wrong ac line

voltage, or if the wrong fuses are installed. Verify that the correct

line fuses are installed before connecting the line cord. Use two (2)

metric size 5 ×20 mm fuses. For 100 V/120 V, use 1 A fuses; for 220 V–

230 V/240 V, use 0.5 A fuses. See appendix A for detailed instructions.

Line cord

The DC205 Precision DC Voltage Source has a detachable, three-wire

power cord for connection to the power source and to a protective

ground. The chassis of the instrument is connected to the outlet

ground to protect against electrical shock. Always use an outlet

which has a properly connected protective ground.

Service

The DC205 Precision DC Voltage Source does not have any user

serviceable parts inside. Refer service to a qualiﬁed technician.

Do not install substitute parts or perform any unauthorized modi-

ﬁcations to this instrument. Contact the factory for instructions on

how to return the instrument for authorized service and adjustment.
