WARNING
Before disconnecting the secondary terminals of the current transformer or the connections of the cur-
rent transformer at the unit, ensure that the transformer is short-circuited.
NOTE
Current transducers are generally to be grounded on one side of the secondary.

NOTE
If the generator load is always symmetrically, the current may also be measured in L2 or L3. This must
be considered when configuring the SPM-D11 (refer to CTs (Current Transformer) on page 42). If there
is a possibility that the load may be asymmetrical, the current must be measured in L1.
