Chapter 1 IT-E165A Introduction
IT-E165A is an optional anti-reverse module we prepared for users, suitable for
IT6000 series products (including IT6000B, IT6000C, IT6000D, IT8000).
It is necessary to consider that the voltage/current of the DUT is within the rated
voltage/current range of IT-E165A.
The following models are available:
Model
Voltage
Current
IT-E165A-250
750V
250A
IT-E165A-400
750V
400A
IT-E165A-500
900V
400A
The main functions are as follows:
It can effectively avoid the reverse connection of the DUT. IT-E165A has a
built-in detection circuit to detect the voltage difference to determine whether it
is reversed. If it is reversed, the test circuit is disconnected to ensure the safety
of the DUT and the operator.
1.1 Introduction
The dimensions of IT-E165A are shown in the figure below. Unit: mm
The front panel is shown in the figure below.

The rear panel is shown in the figure below.
1.2 How to Use
1. Make sure that the power of the battery, IT-E165A, and IT6000 is turned
off.
2. Refer to the following diagram to connect the IT6000 series instrument and
the DUT (battery).
Note: The green terminals Sense and IO on the rear panel are reserved
terminals and do not need to be connected.
3. Connect the power cord of IT-E165A.
4. Start the battery and turn on the IT6000 power switch.
5. Turn on the Power switch of the IT-E165A.
If IT6000 (IN) and DUT (OUT) are not reversed, and the voltage difference
between IT6000 (IN) and DUT (OUT) is less than 2V, the indicator will
display RUN (green light);
If there is a reverse connection between IT6000 (IN) and DUT (OUT), or
the voltage difference between IT6000 (IN) and DUT (OUT) is greater than
2V, the indicator will display ERROR (red light). Please recheck whether
IT6000 (IN) and DUT (OUT) are reversely connected, and make sure that
the voltage difference between IT6000 (IN) and DUT (OUT) is less than 2V.
