rating.
This instrument has auto-ranging line voltage input; be sure the supply 
voltage is within the specified range and that voltage fluctuations do not to 
exceed 10 percent of the nominal supply voltage.
Install the instrument so that the detachable power cord is readily 
identifiable and is easily reached by the operator. The detachable power 
cord is the instrument disconnecting device. It disconnects the mains 
circuits from the mains supply before other parts of the instrument. The 
front panel switch is only a standby switch and is not a LINE switch. 
Alternatively, an externally installed switch or circuit breaker (which is 
readily identifiable and is easily reached by the operator) may be used as a 
disconnecting device.
To prevent electrical shock, disconnect the Keysight Technologies P937xA 
from mains before cleaning. Use a dry cloth or one slightly dampened with 
water to clean the external case parts. Do not attempt to clean internally.
Position equipment to ensure easy access to disconnecting device.
