ELECTRICAL CONNECTIONS
1.0 Wiring the Pump (2020/ 3 phase)
Connect the pressure/vacuum pump
at the pump junction box (Figure 5)
using the attached cable. Follow the
GND
instructions to the left for the proper
connections
Turn the main power switch to the
G/Y
"ON" position. Switch the pump on
momentarily and check for proper
rotation as indicated by the rotation
arrow on the pump. Immediately turn
off the pump if the rotation is wrong.
If the rotation is incorrect interchange
any two of the three wires #1, #2 or
#3 in the pump motor terminal box.
1.1 Wiring the Pump (2020/1 phase)
GND
Connect the pressure/vacuum pump
at the pump junction box (Figure 5)
G/Y
using the attached cable. Follow the
instructions to the left for the proper
connections
1.2 Other Connections
Refer to the serial number plate for electrical
requirements. The serial number plate notes the voltage,
phase and hertz, minimum time delay fuse, total machine
amperage, and minimum wire conductor size for the main
power connection.
The main power is connected directly to the line side of
the main power switch. In a 2020 single phase use L1 and
L2 only.
All electrical connections are to be made by a certified
electrician. Refer to local building electrical codes for proper
and safe connections.
For the following items, refer to Figure 6. Run a power
cable from your distribution box to the main control box on
the pile feeder. Turn the main power switch to zero. Using
the appropriate tool, open the latches on the control box
door and open the door.
NOTE: The door is connected to the main box by a ground
wire that should not be removed.
