Required AC Power Connection Drawing Package
The AC power drawing should document the electrical path from the project
220–240V AC source to the approved faucet power component and electronic
controller. The drawing should identify the receptacle or junction location,
AC adapter or transformer, control box, low-voltage sensor cable,
solenoid-valve cable, cable connectors, waterproof penetrations and required
separation from water-supply and drainage components. Final wiring should
remain accessible for commissioning and maintenance.
Complete AC Power Connection Drawing
Shows the complete electrical path from the 220–240V AC project
supply through the approved power adapter or transformer to the
electronic controller, sensor and solenoid valve.
220–240V AC Supply
Identify the project electrical source serving the touchless faucet.
The drawing should clearly note the 220–240V AC, 50/60Hz operating
requirement of the AC configuration.
50/60Hz Frequency
Include the required 50/60Hz supply frequency within the electrical
connection notes so the project electrical system can be verified
before commissioning.
Power Receptacle Location
Where a receptacle is used, locate it inside the cabinet in a dry,
accessible position that does not interfere with the basin, drain,
angle stops or service access.
Junction or Connection Point
Where the approved system uses a fixed electrical connection,
identify the junction location and coordinate it with project
electrical requirements and local codes.
Approved AC Power Adapter
Show the approved adapter or power-conversion component between the
building AC source and electronic controller. The component should
not rest loose on the cabinet floor.
Transformer Location
Where a transformer is supplied as part of the installation
configuration, mount it in a dry, ventilated and serviceable position
away from plumbing leak points.
Controller Power Input
Identify the designated power-input connection on the electronic
control box. Only the approved power component should be connected
to this input.
Electronic Control Box
Mount the controller securely on a vertical cabinet wall or approved
support surface where practical. The enclosure should remain
accessible for inspection and diagnostic testing.
Controller Mounting Height
Position the control box above the lowest cabinet level where
practical to reduce the risk of exposure to cleaning water,
condensation or minor plumbing leaks.
Sensor Cable Connection
Show the low-voltage cable from the faucet's infrared sensor to the
controller. The connector should be fully seated and remain accessible
for commissioning and troubleshooting.
Solenoid Control Cable
Identify the electrical connection between the controller and
motorized solenoid valve. Route this cable independently from
water-supply hoses where practical.
Low-Voltage Wiring Zone
Create an organized routing zone for sensor and valve-control wiring
so these cables are separated from sharp edges, drawer slides,
hinges and plumbing components.
AC and Low-Voltage Separation
Where project conditions require separate wiring routes, show the
physical separation between incoming AC wiring and faucet
low-voltage control cables.
Power Cable Route
Route the power cable directly to the control system without
excessive loops, sharp bends or compression against cabinet
structure.
Cable Strain Relief
Provide sufficient support so cable weight or movement is not
transferred directly to controller plugs, adapter connectors or
solenoid terminals.
Waterproof Cable Grommet
Show a protected grommet or equivalent treatment wherever wiring
passes through a cabinet panel or other enclosure surface.
Cabinet Penetration
Cable penetrations should be smooth and protected from sharp edges.
Where moisture exposure is possible, coordinate the penetration with
an appropriate sealing method.
Water-Supply Separation
Keep AC adapters, electrical connectors and the control box separated
from hot- and cold-water angle stops, braided hoses and valve joints.
Drain Separation
Do not locate the power adapter or controller directly beneath the
lavatory trap, tailpiece or other drainage connections that may leak
during service.
Drip-Risk Exclusion Zone
Establish a dry electrical zone that avoids areas directly below
supply fittings, hose unions, mixing valves and drain joints.
Cabinet Floor Clearance
Do not place the AC power adapter, transformer or loose electrical
connectors directly on the cabinet floor where water may collect.
Service Disconnect Access
Provide a serviceable means of disconnecting faucet power without
removing the basin, countertop or permanent cabinet construction.
Connector Identification
Label or clearly differentiate the power, sensor and solenoid
connectors so field technicians can identify each connection during
commissioning.
Cable Service Loop
Where appropriate, provide a modest service loop sufficient to allow
the controller to be inspected without placing tension on cable
connectors.
Controller Access Zone
Maintain clear working space in front of the control box so power,
sensor and valve connections can be reached during maintenance.
Power Component Removal Path
Show how the transformer or AC adapter can be removed from the cabinet
without disconnecting the basin or dismantling permanent millwork.
Finished AC Electrical Arrangement
The completed installation should present an organized electrical
system with securely mounted components, protected cables, clearly
identified connectors and appropriate separation from plumbing.
