Installing the Sensor
This procedure must be carried out by a certified electrician.
1. Make sure you connect the CTs through the shorting switches
2. Mount the CT(s) on the hot wire(s):
a. If the CT is split-core: Open the CT, and close it around the hot wire.
b. If the CT is solid-core: Disconnect one of the ends of the hot wire
from the panel, insert it through the CT, and then reconnect it to the
panel.
panel.
c. In both cases, make sure the CT is placed on the wire so that the
direction of current flow on the wire is from the side marked "P1" or
"K" on the CT, to the side marked "P2" or "L" on the CT.
"K" on the CT, to the side marked "P2" or "L" on the CT.
3. Connect the three CTs to the inputs I1- I3, by performing the following
procedure to all three CTs:
a. Use 1.0-4.0mm2 (12-17 AWG) wires. Make sure that the wire gauge is
suitable for carrying 5Amms for the length of wire required, without
a significant voltage drop.
a significant voltage drop.
b. Connect the PAN-42 sensor's terminal marked as "+" to the CT's
terminal marked as "S1" or "K"
c. Connect the PAN-42 sensor's terminal marked as "–" to the CT's
terminal marked as "S2" or "L"
4. Connect the voltage inputs:
a. Connect one to three phases L1, L2, L3 (R, S, T) and the neutral wire
to the appropriate PAN-42 inputs, making sure each phase passes
through an MCB (see Figure 2).
through an MCB (see Figure 2).
b. Make sure that you use the same phase for the current and voltage
inputs; that is, L1 and I1 are for the same phase, L2 goes with I2, and
L3 goes with I3.
L3 goes with I3.
