5 Getting Started
Before connecting and powering up the instrument, please review and go through the
instructions in this chapter.
5.1 Input Power Requirements
The AC input accepts line voltage input within:
Voltage: 190 V – 250 V
Frequency: 47 Hz – 63 Hz
Maximum power consumption: 9832B: 2500 VA; 9833B: 3800 VA
Before connecting to an AC outlet or external power source, make sure that the power switch is
in the OFF position and verify that the AC power cord, including the extension line, is
compatible with the rated voltage/current and that there is sufficient circuit capacity for the
power supply.
Follow the illustrations below to connect the new AC power cord to the AC input of the source
in the rear panel.
Connection of the 9832B or 9833B to an AC power source should be made by a
qualified electrician or other qualified personnel. Incorrect wiring may damage the
source or cause a fire hazard.
5.1.1 North American Split Phase Power
Split phase is commonly used in North American to provide 208 to 240 Volts. This
requires two wires that are both hot. For example 110 V and, 110 V resulting in 220 V
across them. The included cable may be used in most regions by adding a band of blue
electrical tape on each end of the white wire to identify both the black and white with
blue band as hot. The green trace yellow wire is always used for ground and must be
connected properly. Check with your local Authority Having Jurisdiction for clarification.
The power cable that is shipped with the instrument is preassembled from the factory.
The following instruction will provide information for changing the power cable for split
phase.
1. Verify that the source power in your facility can provide the minimum voltage and
The included AC power cord is safety certified for this instrument operating in the
rated range. If an extension cable is added, be sure that it can meet the required
power ratings for this instrument. Any misuse with wrong or unsafe cables will
void the warranty.
