Powering the 4200A-SCS
Operating the instrument on an incorrect line voltage may cause damage, possibly voiding
the warranty.
The power cord supplied with the 4200A-SCS 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 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.
The 4200A-SCS operates from a line voltage in the range of 100 V ac to 240 V ac at a frequency of
50 Hz or 60 Hz. Line voltage is automatically sensed, but line frequency is not.
To connect and power the unit:
1. Check to be sure that the operating voltage in your area is compatible.
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 supplied line cord to a grounded ac line power receptacle.
4. Turn the power ON using the front-panel power switch.
