Q:  What is the burden of the AC Cassettes when measuring a CT or a VT?

A:  CT - the burden of our current cassette varies depending on which range is being used.  At full load the burden is 140uW for the 1Aamp range and 875uW for the 5 amp range.  VT - each leg of the voltage measuring cassette offers an impedance of approximately 950K ohm to system 0V (usually neutral).

Q:  Can I Hot Swap a Cassette?

A:  No. There is however, one exception to the rule.  A Digital Input Cassette can be removed while power is applied to the unit but not inserted.

Q:  None of the relays in the output cassettes are functioning correctly?

A:  Ensure that the shorting link is connected between TB1 1 & 2.
