• The relay specifications are as follows:
CT Inputs • When the HBA or the HS alarm is to be used with the E5CN-@@H@ or the
E5CN-@@HH@, connect a current transformer (CT) across terminals 14
and 15 or terminals 13 and 15 (no polarity).
• When the HBA or the HS alarm is to be used with the E5AN/EN-@@H@
or E5AN/EN-@@HH@, connect a current transformer (CT) across termi-
nals 14 and 15 or terminals 15 and 19 (no polarity).
Event Inputs • When event inputs are to be used with the E5@N-@@@B, connect to ter-
minals 11 to 13.
• Use event inputs under the following conditions:
• The outflow current is approximately 7 mA.
Polarities during no-contact input are as follows:
E5CN/CN-U SPST-NO 250 VAC 1 A
E5AN/EN SPST-NO 250 VAC 3 A
E5CN E5CN-U
