If high power dissipation equipment is rack mounted next to the 2600B, it could cause
excessive heating. To produce specified 2600B accuracies, maintain the specified ambient
temperature around the surfaces of the 2600B. In rack configurations with convection cooling
only, proper cooling practice places the hottest non-precision equipment (for example, the
power supply) at the top of the rack away from and above precision equipment (such as
the 2600B).
Mount precision equipment as low as possible in the rack, where temperatures are coolest.
You can add space panels above and below the 2600B to help provide adequate airflow.
Turning the instrument on and off
The 2600B operates from a line voltage of 100 V to 240 V at a frequency of 50 Hz or 60 Hz. Line
voltage is automatically sensed (there are no switches to set). Make sure the operating voltage in
your area is compatible.
Follow the procedure below to connect the 2600B to line power and turn on the instrument.
Operating the instrument on an incorrect line voltage may cause damage to the instrument,
possibly voiding the warranty.
To turn a 2600B on and off:
1. Before plugging in the power cord, make sure that the front-panel POWER switch is in the
off (O) position.
2. Connect the female end of the supplied power cord to the ac receptacle on the rear panel.
3. Connect the other end of the power cord to a grounded ac outlet.
The power cord supplied with the 2600B 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 chassis ground 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.
