The 4520 allows manufacturers to perform AC Hipot, DC Hipot, Insulation Resistance and Ground Bond tests in a single instrument. The 4520 offers incredible value if you want to perform multiple electrical safety tests in a single instrument. Test functionality includes a 5 kV, 100 mAAC Hipot (500 VA), 6 kV, 10 mADC Hipot, Insulation Resistance and a 30 Amp Ground Bond. Equipped with the latest technology and features the 4520 is the right solution for a variety of electrical safety testing applications.
To connect the 4520 to a DUT, first connect the black return lead into the front panel return output jack. If you are performing a ground bond test then connect the high current lead to the front panel current output jack. Next connect the high voltage lead (w/ red clip) or probe, which-ever one you are using for your application into the high voltage jack on the front panel.
Then attach the black return clip to exposed or dead metal located on the chassis of the DUT. Always connect the ground return first.
Again if you are performing ground bond testing, attach the high current lead to the ground/earthing contact. If you are using the high voltage clip, make sure you attached the red clip to the current carrying conductors of the DUTs circuitry. If you are using the test probe, simply apply the probe to the appropriate current carrying conductors.
Adapter Box Connection
The adapter box is provided as an optional accessory for the 4520. This provides an easy way to connect to a DUT that is terminated in a two-prong or three-prong line cord.
First connect the black return lead into the front panel return output jack. Then connect the high current lead from the adapter box into the front panel output current jack on the 4520. Then connect the high voltage lead from the adapter box into the front panel high voltage jack on the 4520. Next attach the black return clip to exposed dead metal located on the CHASSIS of the DUT. Always connect the ground return first. Finally plug in your DUT into the adapter box.
