Page 8: Field Installation
Chapter Field Installation Some power meters have 5A inputs which may have the option of a shorting bar that connects the negative inputs together. The inputs MUST NOT connect to each other. The 3 outputs of the TCA-5 must be separated from each other and the negative output wires must not be tied to each other, otherwise spurious results or saturation of the high gain... -

Page 17: Frequently Asked Questions
Chapter FAQs Frequently Asked Questions How can I tell if the amplifier is clipping? The voltage across the output terminals is above 250mV RMS. Correct this by using a larger wire gauge or moving the TCA-5 closer to the meter. Does output clipping damage the unit? Clipping the output signal does not harm the TCA-5 as long as the output current remains less than 5 amps, as in the case when the output impedance is greater than 50m-ohms or the output wires... - Page 18 Can the TCA-5 be used with 333mV current sensors? The TCA-5 includes a 90 degree phase shifter. It can only be used with 333mV sensors to report current, NOT POWER. I had the 50Hz selector on by mistake. Is my collected data any good? Yes, the phase angle will be reported 0.6 degrees higher than actual, which is also about 0.6% low for a PF of 0.866.
