Connect line power
The Model 2657A operates from a line voltage of 100 V to 240 V at a
frequency of 50 Hz or 60 Hz. Make sure the operating voltage in
your area is compatible.
The power cord supplied with the Model 2657A contains a
separate 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. Failure to use a grounded outlet may result in
personal injury or death due to electric shock.
Operating the instrument on an incorrect line voltage may cause
damage to the instrument, possibly voiding the warranty.
To connect line power:
1. Make sure the front panel power switch is in the off (0) position.
2. Connect the socket of the supplied power cord to the power
module on the rear panel.
3. Connect the plug of the power cord to a grounded AC outlet.
