Fig. 4 Example CTM 025 with 2 windings for a 12 A motor

Fig. 5 Example 1, 2 and 3 windings.

NOTE: Normally the appropriate Current Transformer (CTM XXX) will have

been ordered and shipped with the Emotron M10. Check that this is the

case; contact the supplier if in doubt.

CAUTION: Terminals 1 and 2 (S1, S2) carry live voltage.

NOTE: The current transformer connection and orientation are not polarity

sensitive, but must be connected to the same phase that is being referenced

for terminal 9 of the Emotron M10.
