Featuring 60 Amps of Ground Bond test current, the 2660 is designed for stand alone Ground Bond test applications or as a companion instrument to our Hipot testers. It has the capability to interconnect with all of our Hipot testers for Electrical Safety testing applications. Equipped with the latest technology and features it is a perfect solution for higher current production line Ground Bond testing.

• Cost-Effective 60 Amp Ground Bond Tester
• 5 Test Set-up Memories
• Milliohm Offset Capability
• Fully Adjustable Electronic Dwell Settings
• Tamper Proof Front Panel Controls

1. LCD DISPLAY: The liquid crystal display is the main readout for the operator and programmer of the test settings and test results.   
2. RESET SWITCH: This is a momentary contact switch. To reset the system for the next test, press and release the red Reset switch. This switch may also be used to abort a Test in Progress.
3. TEST SWITCH: This is a momentary contact switch. Press the green switch to turn on the high current output when in the test mode.
4. POWER SWITCH: Rocker-style switch with international ON ( | ) and OFF (0) markings.
5. SET KEY: Use this key to advance forward through the setup menus.
6. DOWN ARROW (∨): Use this key to decrement numeric values in the setup mode. This key also used to toggle ON/OFF functions.
7. UP ARROW (∧): Use this key to increment numeric values in the setup mode. This key also used to toggle ON/OFF functions.
8. EXIT KEY: Use this key when you desire to enter the Run Mode to initiate a test. This key may also be used to save settings into memory.   
9. TEST LED INDICATOR: This red LED lights to indicate to the operator that a test is in process.
10. CURRENT OUTPUT JACK: For the connection of the detachable 6-foot red high current test lead or adapter box. This jack is always used when performing a Ground Bond test.
11. RETURN OUTPUT JACK: For the connection of the detachable 6-foot black return test lead. This jack is always used when performing a test.

1. THERMAL FAN: Thermally switched fans provide cooling when needed.
2. REMOTE OUTPUT: 9 pin D subminiature female connector for monitoring PASS, FAIL, and PROCESSING output relay signals, as well as remote START and RESET outputs.
3. CALIBRATION ENABLE: This recessed switch when depressed allows access to the calibration control program.
4. REMOTE INPUT: 9 pin D subminiature male connector for remote control of test and reset functions as well as withstand processing input.
5. INPUT POWER RECEPTACLE : Standard IEC 320 connector for connection to a standard NEMA style line power (mains) cord.
6. INPUT POWER SWITCH: Line voltage selection is set by the position of the switch. In the left position it is set for 115-volt operation, in the right position it is set for 230-volt operation.
7. CHASSIS GROUND (EARTH) TERMINAL: This safety terminal should be connected to a good earth ground before operation.

Test Connections
To connect the 2660 to a DUT, first connect the black return test lead to the return output jack on the front panel of the 2660. Then connect the high current lead (w/red clip) into the high current output jack on the front panel.

Next attach the black return clip to exposed or dead metal located on the chassis of the DUT. Always connect the ground return first. Then connect the high current lead to the ground/earthing contact.

2660 & 2900 Series Interconnection

The 2660 and the 2900 series of instruments can be interconnected together to form a complete test system. First connect the interconnect cable (p/n 99-1007-01) to the front panel return jack of the hipot tester to the return output jack on the front panel of the 2660.

You have the choice to perform your hipot and ground bond testing sequentially (ground bond first, then hipot) or simultaneously (ground bond and hipot at the same time).

For sequential testing use the following connections:

Locate the cable marked "99-10003-01 SEQUENTIAL." Attach the male connector (male connector with blue tubing) with two cables coming from it, to the female input connector of the 2660. Attach the shorter of the two remaining cables with female connectors (female connector with blue tubing), to the male output connector of the 2660 and the longer cable to the male signal input/output connector (female connector with red tubing) on the rear panel of the Hipot.

For simultaneous testing, use the following cable connections:

Locate the cable marked "99-10004-01 SIMULTANEOUS." Attach the male connector (male connector with blue tubing) with two cables coming from it, to the female input connector of the 2660. Attach the shorter of the two remaining cables with female connectors (female connector with blue tubing), to the male output connector of the 2660 and the longer cable to the male signal input/output connector (female connector with red tubing) on the rear panel of the Hipot.

After your testers are interconnected you may then connect the system to a DUT. First connect the return lead (p/n 99-10238-01) to the front panel return jack on the 2660. Then connect the high current lead (p/n 99-10239-01) to the high current output jack on the front panel of the 2660. Then connect the high voltage lead (p/n 102-055-913) to the front panel high voltage output jack on the 2900 series instrument.

Then connect the return to exposed or dead metal located on the chassis of the DUT. Always connect the ground return first. Then connect the high current lead to the ground/earthing contact of the DUT. Lastly connect the high voltage lead to the line and neutral contacts of the DUT.
