# Quiz — Environment & Siting: 10 Questions with Answers

> 10 multiple-choice questions on siting: M1 and G3 altitude limits, IP66 scope, mounting clearances, fan airflow direction, drip loops, and gland sealing.

Ten questions from the [Environment & Siting](/environment/choosing-the-location) group. Work through all ten before scrolling to the key. Suggested pass mark: **8 / 10**. Each miss points to a source page — re-read it, not the whole group.

## Questions

**1.** Both Kent hybrid inverter platforms carry an ingress protection rating of:

* A. IP54
* B. IP65
* C. IP66
* D. IP68

***

**2.** The maximum installation altitude for the Kent M1 Hybrid Inverter is:

* A. 1 000 m
* B. 2 000 m
* C. 3 000 m
* D. 4 000 m

***

**3.** The maximum installation altitude for the Kent G3 Hybrid Inverter is:

* A. 2 000 m
* B. 2 500 m
* C. 3 000 m
* D. 4 000 m

***

**4.** IP66 protects against heat and direct sun exposure. True or false?

* A. True — IP66 covers all environmental exposure
* B. False — IP66 covers dust and water jets only; do not install in direct sunlight regardless of rating
* C. True, but only below 40 °C ambient
* D. False — IP66 only covers immersion

***

**5.** Kent M1 mounting clearances are:

* A. ≥ 300 mm on the sides, ≥ 500 mm below
* B. ≥ 500 mm on all sides
* C. ≥ 150 mm on all sides
* D. ≥ 700 mm between units, no other clearance required

***

**6.** When mounting multiple Kent G3 units side by side, the minimum clearance between units is:

* A. 300 mm
* B. 500 mm
* C. 700 mm
* D. 1 000 mm

***

**7.** The Kent G3 cooling fan draws air:

* A. In from the right side, out to the left
* B. In from the bottom, out through the top
* C. In from the left side, out to the right
* D. Uniformly through front vents — no directional airflow

***

**8.** A cable drip loop is correctly formed when:

* A. The cable exits the gland horizontally and curves up before entering the conduit
* B. The cable forms a U-bend below the gland entry point before rising to the conduit
* C. The cable is sealed with silicone at the gland and exits vertically upward
* D. The cable is looped once around the mounting bracket

***

**9.** An unused cable entry gland on a Kent inverter must be:

* A. Left open — factory knock-outs are sealed from inside
* B. Sealed with the supplied bung or an equivalent IP-rated plug
* C. Covered with insulation tape
* D. Fitted with a blank conduit section

***

**10.** The site photograph that must be taken before any tools are used or any work begins is:

* A. A photo of the DB panel only
* B. An overall site photo showing the intended mounting wall, surroundings, and any hazards
* C. A photo of the delivery packaging
* D. No pre-work photo is required

## Answer key

| Q  | Answer | Why                                                                                                                                                             |
| -- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 1  | **C**  | Both the Kent M1 and Kent G3 are rated IP66 — dust-tight and protected against powerful water jets.                                                             |
| 2  | **B**  | The Kent M1 installation altitude limit is ≤ 2 000 m. Above this, derated or prohibited.                                                                        |
| 3  | **D**  | The Kent G3 installation altitude limit is ≤ 4 000 m — a higher ceiling than the M1.                                                                            |
| 4  | **B**  | IP66 covers ingress. Direct sun causes overheating regardless of IP rating. Both manuals prohibit installation in direct sunlight.                              |
| 5  | **A**  | Kent M1 clearances: ≥ 300 mm on the sides and ≥ 500 mm below the unit. These gaps are cooling, not aesthetics.                                                  |
| 6  | **C**  | Kent G3 side-by-side clearance between units is 700 mm minimum to allow fan airflow between cabinets.                                                           |
| 7  | **C**  | The Kent G3 fan draws air in from the LEFT side and exhausts it out to the RIGHT. Never block the left or right side.                                           |
| 8  | **B**  | A drip loop forms a U-bend below the gland entry point. Water runs down the cable, around the bottom of the U, and drips off — it cannot track into the gland.  |
| 9  | **B**  | Every unused gland entry must be sealed with the supplied bung or an IP-rated equivalent. Open entries defeat the IP66 rating.                                  |
| 10 | **B**  | An overall site photo before work starts is a Kent requirement — it records the pre-installation condition of the wall, surroundings, and any existing hazards. |
