Low-Voltage Wiring Zone

Provide an organized route for battery, sensor and solenoid wiring so all cables remain visible and accessible for commissioning and future maintenance.

Cable Strain Relief

Support cables so the battery box or controller connectors do not carry the weight of hanging wiring. Avoid tension on plug connections.

Cable Service Loop

Provide a modest service loop where appropriate so the battery enclosure or controller can be moved slightly during inspection without disconnecting wiring.

Waterproof Cable Grommet

Show a protected grommet wherever the battery or control cable passes through cabinet panels or supporting construction. The penetration should not expose the cable to sharp edges.

Dry Electrical Zone

Reserve a dry portion of the cabinet for the battery enclosure, controller and electrical connectors. Avoid areas directly below water-supply valves, hose unions or drainage joints.

Water-Supply Separation

Keep the battery enclosure and electrical connectors separated from G1/2 water connections, braided supply hoses, mixing valves and solenoid hydraulic fittings.

Drain Separation

Do not install the battery pack directly beneath the lavatory drain, trap or tailpiece where maintenance leakage could expose the electrical system to moisture.

Cabinet Floor Clearance

Mount the battery box above the lowest cabinet level where practical. This reduces exposure to cleaning water, condensation and minor plumbing leakage.
