CONNECTIONS

DUT INPUT POWER CONNECTIONS
Remove the cover plate on the rear panel of the 620L to access the DUT Power Input Connections. These terminals provide the connections from an external power source to the 620L. Once removed, use the black 10 AWG cables (included) to connect to an unbalanced, single-phase power source for applications up to and including 40 amps.
The 220 – 240V US style line power IS NOT suitable to connect to the DUT inputs. This style of power distribution is a balanced type with two HOT or LINE conductors.

BE SURE THAT THE HOT LEAD OF THE POWER SOURCE IS CONNECTED TO PIN 1, L (LINE) TERMINAL OF THE DUT POWER INPUT TERMINAL BLOCK AND THE RETURN OR LOW VOLTAGE LEAD IS CONNECTED TO PIN 2, N (NEUTRAL) TERMINAL OF THE DUT POWER INPUT TERMINAL BLOCK. DO NOT CONNECT A LINE CONDUCTOR TO THE N OR NEUTRAL TERMINAL OF THE DUT POWER INPUT. THIS CONDITION CAN BE VERY DANGEROUS TO THE OPERATOR.

If voltage is applied to pin 2, N (neutral) terminal of the DUT Power Input and you attempt to execute a Run Test or Leakage Current test, a warning message will appear in the displayed messages portion of the screen that says Neutral-V. If you see this message, you will need to correct the voltage problem before the instrument will allow you to execute Run Tests or Leakage Current tests.

DUT OUTPUT POWER CONNECTIONS
Remove the cover plate on the rear panel of the 620L.These connections provide power to the DUT during a Leakage Current or Functional Run test. Once removed, the set of black 10 AWG cables (included) may be used for the DUT Output connections for applications up to and including 40 amps.

TEST LEAD CONNECTIONS
Connect one or more of the black, alligator clip-terminated cables to the Probe-HI and Probe-LO terminals on the rear panel of the 620L. These cables are used to measure leakage current during either a Leakage Current test or a Functional Run test. Connect the red test lead (also terminated in an alligator clip) to the GND terminal on the rear panel of the 620L. This will provide the return connection for all leakage current measurements .

ADAPTER BOX CONNECTIONS
The adapter box may be used for products that are terminated in either a two prong or three prong line cord. Connect the adapter box to the DUT Output L (line) and N (neutral) terminals, and the GND terminal. The adaptor box will now provide power to the DUT during Leakage Current testing and Functional Run testing.

WARNING: THE ADAPTER BOX MAY ONLY BE USED FOR APPLICATIONS UNDER 20 AMPS. IF AN APPLICATION IN WHICH MORE THAN 20 AMPS OF INPUT CURRENT IS REQUIRED, PLEASE USE THE STAND-ALONE INPUT AND OUTPUT CABLES PROVIDED WITH THE INSTRUMENT.
