Power requirements
The M1749B does not have an AC power connection. It is powered by a 19 Volt
DC input from an AC/DC converter. This input does not represent a risk of
personal injury.
Power requirements of the AC adapter
— Input: 100-240VAC, 50-60 Hz, 2.5 - 1 A
— Input power stability: the AC-DC adapter is certified and can operate with
mains supply voltage fluctuations up to ±10% of the nominal voltage.
— Output: 19 VDC, 6 A
The main power cord is the system disconnecting device. It disconnects the
mains circuits from the mains supply.
Using Accessories
Only Keysight-approved accessories shall be used.
Use the AC-DC power adapter and power cord which is supplied with the
product.
See the accessories listed under

Do not remove the DC input plug from the M1749B while it is in an active state.
Make sure the
Status
LED on the DUT-facing side of the M1749B is dark
before disconnecting the DC input.
This is a Safety Protection Class I Product (provided with a protective earthing
ground incorporated in the power cord). The mains plug shall only be inserted in
a socket outlet provided with a protective earth contact. Any interruption of the
protective conductor inside or outside of the product is likely to make the
product dangerous. Intentional interruption is prohibited.
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.
