Important installation notes:
The polarity of the currents are important. The current transformers (CTs) must
be placed on the load wires so that current flows from the side marked "K" or
"P1" to the side marked "L" or "P2". On the secondary side, "K" or "S1" must be
connected to the "+" terminal on PAN-42, while "L" or "S2" must be connected to
the "–" terminal.

connected to the "+" terminal on PAN-42, while "L" or "S2" must be connected to
the "–" terminal.
Never leave a CT’s output unconnected while primary current is flowing. In
case you want to dissemble a CT from the sensor, use the shorting switches.
