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. |
