Making System Pressure Connections
The controller requires one (1) “System Pressure” connection from the system piping to
the enclosure. The connection fitting, 1/2” FNPT, is provided on the bottom, external side of
the enclosure for this purpose. Refer to NFPA 20 (or Publication GF100-30) for correct field
piping procedure of the sensing line between the pumping system and the controller.
Making Electrical Connections
Important Precautions-
Prior to making any field connections:
1. Open door of enclosure and inspect internal components and wiring for any signs of
frayed or loose wires or other visible damage.
2. Verify that the controller information is what is required on the project:
• Firetrol catalog number
• Motor voltage matches incoming line voltage and frequency
- Confirm incoming voltage matches nameplate before energizing controller
• Pump motor horsepower size matches controller
3. Project electrical contractor must supply all necessary wiring for field connections
in accordance with the National Electrical Code, local electrical code and any other
authority having jurisdiction.
4. Refer to the appropriate field connection drawing for wiring information.
Procedure-
All field connections, remote alarm functions and AC wiring are brought into the enclosure
through the top or bottom conduit entrances as indicated on the dimensional drawing.
Do not place conduit entrances in the sides of the enclosure.
1. Using a hole (conduit) punch, create a hole in the enclosure for the size conduit be-
ing used.
2. Install necessary conduit.
3. Pull all wires necessary for field connections, remote alarm functions, AC power and
all other optional features. Bring enough wire inside the enclosure to make up con-
nections to the appropriate line, load and control terminal block points. Be sure to
consult the appropriate field connection diagram included with the manual. For
proper wire sizing, refer to the National Electrical Code, NFPA 70.
4. Make all field connections to the remote alarm functions and any other optional fea-
tures. Connect motor to controller load terminals.
5. Find nameplate on jockey pump motor and make note of its full load amp rating.
Verity the overload within the controller is set for that number of amps.
6. Verify AC line voltage, phase and frequency with the controller data plate on the en-
closure door prior to connecting. Connect AC power.
7. Check to see that all connections are both correctly wired (in accordance with the
field connection diagram) and tight.
8. Close the enclosure door.
