a)
Confirmation of power supply parameters
The S1465 series signal generator features an 110V/220V adaptive AC power module which
allows either one to be used optionally. In this case, the AC power module is self-adaptive, that is, it
automatically switches the operating state according to external AC supply voltage. Therefore,
please look through the power requirements of rear panel before using the instrument. Table 3.4 lists
the requirements for external power supply when the signal generator is in normal operation.

NOTE
Prevention against mutual interference of power supplies
To avoid instrument hardware damage caused by the interference by the power supply of other
equipment, especially the spike pulse interference generated by high-power equipment, it is
recommended to use a 220 V or 110 V AC regulated power supply to power the signal generator.
b)
Confirmation and connection of power cord
The S1465 series signal generator uses a 3-core power cord interface that complies with the
national safety standard. Before the signal generator is powered on, it must be confirmed that the
protective ground wire of the power cord has been reliably grounded. Floating or poor grounding may
damage the instrument and even injure the operator. It is prohibited to use a power cord without a
protective ground. When connected to a suitable power socket, the power cord realizes grounding of
the instrument enclosure. The power cord should have a rated voltage greater than or equal to250 V
and a rated current greater than or equal to 6A.
When connecting the instrument to the power cord:
Step 1. Confirm that the power cord is undamaged;
Step 2. Use the power cord to connect the rear panel power plug and the properly-grounded
3-core power socket.
WARNING
Grounding
Poor or incorrect grounding may cause instrument damage and even personal injury. Before
powering on the signal generator, make sure that the ground wire is in good contact with the power
supply ground wire.
Please use the power socket with a protective ground. Do not replace the protective ground wire
with an external cable, power cord or autotransformer without grounding protection. If an
autotransformer is required, the common terminal must be connected to the protective ground of the
power connector.
