Liberty Pumps SX-Series - Manual (Page 9)

Mounting the Control Panel
1. Determine mounting location for panel. If
distance exceeds the length of either the fl oat
switch cables or the pump power cables,
splicing will be required. For outdoor or wet
installation, we recommend the use of a SJE-
Rhombus
® liquid-tight junction box with liquid-
tight connectors to make required connections.
You must use conduit sealant to prevent
moisture or gases from entering the panel.
2. Mount control panel with mounting devices
furnished.
3. Determine conduit entrance locations on
control panel.
NOTE: Be sure the incoming power, voltage,
amperage, and phase meet the requirements
of the pump motor being installed. If in doubt,
see the pump identifi cation plate for electrical
requirements.
4. Drill proper size holes for type of connectors
being used.
NOTE: If using conduit, be sure that it is of
adequate size to pull the pump and switch
cables through.
5. Attach cable connectors and/or conduit
connectors to control panel.
FOR INSTALLATION WITHOUT
A SPLICE, GO TO STEP 10;
FOR INSTALLATION REQUIRING
A SPLICE, FOLLOW STEPS 6-9.
6. Determine location for mounting junction box
according to state and local code requirements.
Mount junction box to proper support.
7. Run conduit to junction box. Drill proper size
holes for the type of conduit used. Attach
connectors to junction box.
Installation Instructions
8. Identify and label each wire before pulling
through conduit into control panel and junction
box. Make wire splice connections at junction
box.
9. Firmly tighten all fi ttings on junction box.
10. If a junction box is not required, pull cables
through conduit into control panel.
11. Set motor protective switch:
a) set the dial to match motor full load amps
b) turn dial on motor protective switch to
the ON position
NOTE: Resetting the dial with power applied
to the motor protective switch could start
the motor.
12. Connect pump wires directly to the motor
contactor terminal positions T1, T2, and T3.
NOTE: Three phase motors will run in either
direction. Check pump motor before installation
for proper rotation. To correct rotation, change
pump cable connections on any two terminals
T1-T2-T3.
13. Connect “power-in” conductors to proper
locations: 208/240/480 on 3 position terminal
block. Install tagged factory wire to
appropriate transformer primary voltage
tap.
VERIFY CORRECT OPERATION OF
CONTROL PANEL AFTER
INSTALLATION IS COMPLETE.
