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 an SJE-Rhombus
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 (mounting fl anges are integral
to control panel).
3. Determine conduit entrance locations on control
panel as shown in Figure 4. Check local codes
and schematic for the number of power circuits
required.
NOTE: Be sure the proper power supply voltage,
and phase are the same as 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.
You must use conduit sealant to prevent mois-
ture or gases from entering the panel.
5. Attach cable connectors and/or conduit connectors
to control panel.
FOR INSTALLATION WITHOUT A SPLICE,
GO TO STEP 11;
FOR INSTALLATION REQUIRING A SPLICE,
FOLLOW STEPS 6-10.

6. Determine location for mounting junction box
according to local code requirements. See Figure 5.
Do not mount the junction box inside the sump or
basin.
7. Mount junction box to proper support.
8. Run conduit to junction box. Drill proper size holes
for the type of conduit used. Attach liquid-tight
connectors to junction box.
9. Identify and label each wire before pulling through
conduit into control panel and junction box. Pull
pump power cables and control switch cables
through connectors into junction box. Make wire
splice connections at junction box.
10. Firmly tighten all fi ttings on junction box. Ensure
all cable connectors are liquid-tight and sealed.
11. If a junction box is not required, identify and label
cables on both fl oat and stripped ends.
12. Connect pump and fl oat wires to proper position
on terminals. See schematic inside control panel
for terminal layouts.
13. Connect control/alarm and pump power conductors
to proper position on terminals. See schematic
inside control panel for terminal connections.
NOTE: It is the recommendation of the factory to use
separate pump and control/alarm power sources.
VERIFY CORRECT OPERATION OF CONTROL
PANEL AFTER INSTALLATION IS COMPLETE.
