Option 2. Control Wiring Solution using a Low Voltage Dry Contact
from a Utility-Supplied Device
•
•
This method requires low voltage to be passed across a Utility-supplied contact.
Used by Nova Scotia Power, the dry contact is part of their Time-Of-Day meter.
The transformer is only needed to provide low voltage to the dry contact. Examples of
components:
• Marcus 12/240 to 12/24 AC transformer - MRCMO50A.
• Schneider relay - TLPRPM21B7 and Schneider relay base - TLPRPZF2.
• Use a “normally open” contact if the Utility signal is an open contact for Off-Peak periods.
(Shown) This is the standard in Nova Scotia and requires the NSPi meter lead wire
#113397 to connect to the NSPi meter dry contact.
• Use a “normally closed” contact if the Utility signal is a closed contact for Off-Peak periods.
(Not Shown)
• The suggested transformer and relay panel dimensions are 8” w x 8” h x 4” d.
