Before you start
Confirm two things before you drill:- Wall construction — solid masonry or an engineered mounting surface rated for the unit’s weight. No hollow walls, no decorated-cavity surfaces, no partition boards.
- Unit weight — Kent M1 is approximately 19 kg; Kent G3 is approximately 42 kg plus bracket. Kent G3 is a two-person lift. Plan the labour accordingly.
Mounting rules
Anchors per the platform installation manual
Anchor type, size, count, and minimum embedment depth all come from the platform installation page — not from site preference or what is in the bag. No substitutions on hollow brick or aerated block.
Level the bracket before hanging the unit
A tilted bracket twists the chassis, stresses door gaskets, and creates a permanent drip-path bias on rain-exposed installs. Use a spirit level, not eye judgment.
Mount vertically — Kent G3 maximum incline ±5°
Both platforms mount vertically. Kent G3 has a maximum incline tolerance of ±5° from vertical — beyond that, output derates. Never install Kent G3 forward-tilted or horizontal.
Positive engage and secure before wiring
Hang the unit on the bracket and confirm it positively engages the mounting points. Secure per the platform page before any wiring begins. No wiring on an unsecured unit.
Kent G3 incline reference
| Incline from vertical | Outcome |
|---|---|
| 0° – ±5° | Within specification |
| Beyond ±5° | Output derates — not acceptable |
| Forward tilt or horizontal | Not permitted under any circumstance |
Service access requirements
Give every service technician who comes after you a reasonable working environment:Display at eye level
Where the wall allows, position the display so it is readable without a ladder. Reading fault codes in the rain from three rungs up is how mistakes happen.
Breakers within reach
All isolators and circuit breakers must be operable by a standing person. If local regulations specify a maximum height for live-working access, that height governs.
Covers open fully
Check the swing arc of every access cover against nearby pipes, walls, and corners before finalising the position. A wiring compartment door that hits a rainwater pipe on first opening is a problem you created.
Kent G3 bottom ≥ 500 mm above ground
The base of a Kent G3 unit must be at least 500 mm above ground level. This is both the splash-protection line and the minimum working clearance for bottom-entry cable management.
The 500 mm bottom-clearance on Kent G3 is also the same clearance zone required for front service access. A unit mounted to just meet this minimum still needs the 500 mm front clearance in addition — they are separate requirements, not the same space.
Common mistakes
Reusing old plastic plugs for a 42 kg unit
Reusing old plastic plugs for a 42 kg unit
Old anchors in an old wall are unknowns. Kent G3 at 42 kg plus dynamic loads is not the application for a plastic plug from a previous tenant’s shelf bracket. Drill fresh holes, fit rated anchors, torque to specification.
Mounting high 'out of the children's reach'
Mounting high 'out of the children's reach'
Height creates safety through inaccessibility, but it also creates inaccessibility for every technician who follows you. Locks, cover panels, and childproof isolator handles manage child safety. Altitude is not a substitute and it is not acceptable at the cost of service access.
Forgetting the cover swing next to a pipe or corner
Forgetting the cover swing next to a pipe or corner
A wiring compartment that cannot open fully on a Kent inverter is a tool-inaccessible compartment. Check the full 90° (or 180°) swing arc of every cover against every obstacle before drilling the first anchor.
