Power on the instrument
The Model 2461 operates from a line voltage of 100 V to 240 V at a
frequency of 50 Hz or 60 Hz. The instrument senses the line voltage
automatically. Before connecting line power, make sure the operating
voltage in your area is compatible.
The power cord supplied with the Model 2461 contains a separate
protective earth (safety ground) wire for use with grounded outlets.
When proper connections are made, the instrument chassis is
connected to power-line ground through the ground wire in the
power cord. In addition, a redundant protective earth connection is
provided through a screw on the rear panel. This terminal should be
connected to a known protective earth. In the event of a failure, not
using a properly grounded protective earth and grounded outlet may
result in personal injury or death due to electric shock.
Do not replace detachable mains supply cords with inadequately
rated cords. Failure to use properly rated cords may result in
personal injury or death due to electric shock.
To connect line power:
1. Make sure the front panel power switch is in the off (O) position.
2. Connect the socket of the supplied power cord to the power
module on the rear panel.
