Description
The differential earth relays CT-1 can be connected to the following toroidal current transformers.
They must be crossed by the cables of the line to be controlled; insert the phases and neutral if present.
The earth cable must NOT cross the current transformer.
NOTE: Twist the connection wires between the toroid and the relay, keep them away from the power cables, and in the presence of strong electromagnetic fields use a shielded lead.
Separately twist the pair of signal cables (terminals 1-2) from the control circuit pair (terminals 3-4) where present. Reduce the distance between the toroid and the relay to the minimum.
