VCOM AX20-B Control Panel Installation Manual
Installing the Control Panel - Floats and Pumps
Power cords for the floats and pumps should be pulled through the cord grips from inside the access
riser to the inside of the splice box. Pull enough cord to allow the cords to extend 6" outside the
access lid on the top of the external splice box shown below. This allows for the splices and wire nuts
to be maintained in the years ahead. Tighten the cord grips around the float and pump cords so that
they can no longer be pulled and will prevent sewage or gasses from seeping into the external splice
box. Each of the cord grips should have either a cord or dummy plug (provided) secured in the grip.
Test the tightness of the cord grips by pulling on each wire to ensure that they are tight.
Wiring between the external splice boxes and control panel should be run in either ¾" or 1" conduit.
Use sweep 90 elbows to connect to the bottom connector of the external splice box and below grade
beneath the control panel. Install/solvent weld the conduit plug (provided) in the unused socket of the
external splice box if only one conduit is required. Hard conduit is required for the complete length of
the electrical runs with solvent welds at each connection. Use standard conduit adapters and lock
rings inside the bottom of the panel. DO NOT DRILL PENETRATIONS INTO THE PANEL ON THE
TOP, SIDES, OR BACK OF THE PANEL – BOTTOM PENETRATIONS ONLY.
When wiring between the panel and the external splice boxes, use 14 gauge stranded copper wire for
float wires. Use the supplied blue lithium wire nuts to tie float neutrals together at the external splice
box and run a single neutral to the control panel. Use 12 gauge twisted copper wire for the pump(s)
with black (load), white (neutral), and green (ground) wires. Additionally it is useful to pull an extra
wire ("pull wire") through the conduit. Leave 6"- 8" of wire length inside the panel to connect to the
terminal strip so that all connections are easily accessed and maintained. Wire that is improperly
sized (too small) can cause excessive voltage drop, poor pump performance, and premature failure,
so please only use the specified wire gauge/sizes. Splices that are not waterproof will cause
malfunction of the pump and controls if water should leak into the splice box. Splice box female
threads and lids should be clean and tightened enough to compress the O'ring in the lid to prevent
water penetration.
