Inspection and Installation
AC Power Input Level
This series power supply operate at the following AC power input.
• Voltage 1: 176V to 264V, 47 to 63 Hz
• Voltage 2: 99V to 121V, 47 to 63 Hz
When IT-M3141D/IT-M3142D works at Voltage 2, the total output power of 2
channels in parallel is limited, and can only reach 600W after parallel connec-
tion. To achieve full power output, please use the input voltage of Voltage 1.
For more information, please refer to the specifications of the corresponding
model.
Connecting the Power Cord
To connect the power cord:
1. Make sure that the front-panel power switch is in the OFF position.
2. Connect the female end of the supplied line cord to the AC receptacle on the
rear panel.
3. Connect the plug of the power cord to a grounded AC outlet.
2.6 Connecting the Device Under Test (DUT)
The instrument supports two connection methods between power supply and
DUT: Local measurement and Remote sensing. This series power supplies in-
clude built-in circuit that connect or disconnect the ± sense terminals from their
corresponding ± output terminals. As shipped, the sense terminals are internally
connected to the output terminals. This is referred to as Local measurement. If
you need to use remote sensing, after making the connection, be sure to turn
