Field Wiring
This section describes how to wire 115 VAC to the power supply, how to wire a solenoid valve’s power
through the 82-5221, and how to wire a remote relay contact into the 82-5221 (optional).
1. Turn off or unplug power to the 82-5221.
2. Open the housing door.
Power Wiring
3. Guide a 3-conductor cable or 3 wires in conduit through the conduit hub on the bottom of the
housing. Use appropriate conduit fittings and construction technique for the environmental rating
of the housing. The housing is rated NEMA 4X.
4. Connect one end of the three wires to the L, N, and ground terminals on the power supply.
5. Connect the other end of the three wires to the line, neutral, and ground terminals on a 115 VAC
power source (as shown in Figure 5 and Figure 6 below).
Solenoid Wiring
6. Guide a 2-conductor cable or 2 wires in conduit through the conduit hub on the bottom of the
housing. Use appropriate conduit fittings and construction technique for the environmental rating
of the housing. The housing is rated NEMA 4X.
7. Connect one end of the two wires to the “Solenoid Control” terminals on the Field Wiring
Terminal Strip as shown in Figure 5 or Figure 6 below.
8. Connect the other end of the wires to the + or line terminal on a 24 VDC or 115 VAC power source
and to the solenoid valve’s + or line input as shown in Figure 5 or Figure 6 below.
9. For a DC-powered solenoid valve, connect the - terminal on the 24 VDC power source to the
solenoid valve’s - input as shown in Figure 5 below.
10. For an AC-powered solenoid valve, connect the N terminal on the 115 VAC power source to the
solenoid valve’s N input as shown in Figure 6 below.
Remote Relay Contact Wiring
Connecting the 82-5221 to a remote relay contact is is not necessary for operation. Connecting the
82-5221 to a remote relay contact provides another way to cut the power line to the solenoid valve. If
you do connect the 82-5221 to a remote relay contact, the relay contact set used must be normally open
and the relay must be configured as normally energized.
11. Remove the jumper from the Field Wiring Terminal Strip.
NOTE:
If you are not connecting a remote relay contact to the 82-5221, the jumper must stay
installed.
12. Guide a 2-conductor cable or 2 wires in conduit through the conduit hub on the bottom of the
82-5221 housing. Use appropriate conduit fittings and construction technique for the
environmental rating of the housing. The housing is rated NEMA 4X.
13. Connect the wires to the “To Alarm Contacts” terminals on the Field Wiring Terminal Strip as
shown in Figure 5 and Figure 6 below.
14. Guide the other end of the wires to the normally open remote relay contact. Use appropriate
conduit fittings and construction technique for the environmental rating of the relay contact’s
housing. RKI’s controllers are rated NEMA 4X.
