5.2 Методе ожичења

The DIHOOL Disconnect Switch Box supports two primary wiring methods:

Two wiring methods: Type A with cable gland and Type B with solar terminals

Слика 5.2: Illustration of Type A (direct wiring with cable gland) and Type B (plug-and-play with solar terminals) wiring methods.

Type A: Direct Wiring through Waterproof Connectors and Terminals

For this method, use 5-10mm² (10-4AWG) cables.
Feed the cables through the waterproof cable glands at the bottom of the enclosure.
Strip the cable insulation and crimp appropriate terminals onto the wires.
Connect the positive (+) and negative (-) wires from the solar panel string to the corresponding terminals inside the box.
Connect the output wires to your MPPT controller or inverter.
Уверите се да су све везе чврсте и безбедне.
Tighten the cable glands to maintain IP65 rating.

Type B: Solar Connectors (MC4) for Plug-and-Play

This method uses MC4 solar terminals for faster and safer connection.
Use 6mm² (10AWG) cables with pre-attached MC4 connectors.
Connect the MC4 connectors from your solar panel string directly to the input MC4 ports on the disconnect box.
Connect the output MC4 ports from the disconnect box to your MPPT controller or inverter.
Ensure all MC4 connections are fully seated and locked.

Applicable cable types for MC4 solar terminals

6. Упутство за употребу

6.1 DC Circuit Breaker Operation

The integrated DC circuit breaker acts as the main disconnect switch. It is designed to interrupt the DC current from the solar panels to the rest of the system.

Да бисте укључили: Push the breaker switch to the "ON" position (typically indicated by a color, often red).
Да искључите: Push the breaker switch to the "OFF" position (typically indicated by a color, often green). This disconnects the solar array from the system.
In case of an overcurrent event, the breaker will automatically trip to the "OFF" position. Investigate the cause before resetting.

6.2 Surge Protector Status

The surge protector is designed to protect your system from lightning strikes and voltagе сургес.

The surge protector has an indicator light.
If the indicator light is зелена, the surge protector is functioning correctly.
If the indicator light turns црвена, it indicates that a lightning strike or significant surge has occurred, and the surge protection module needs to be replaced.

Слика 6.1: This image illustrates the difference between DIHOOL's surge protector, which uses a standard lightning protection chip for effective voltage release, and other brands that may use less effective piezoresistors.

7. Одржавање

7.1 Општи преглед

Periodically inspect the enclosure for any signs of damage, cracks, or loose connections.
Ensure the transparent viewing window is clean for clear visibility of the breaker and surge protector status.
Check that all cable glands are securely tightened.

7.2 Surge Protector Replacement

If the surge protector indicator turns red, the module has absorbed a surge and needs replacement to ensure continued protection.

УПОЗОРЕЊЕ: Disconnect all power to the solar array and the system before attempting to replace the surge protector.
Отворите кућиште.
Carefully remove the old surge protector module from its DIN rail mounting.
Install a new, compatible surge protector module (DC 1000V 2P 20kA / 40kA Type 2).
Добро затворите кућиште.
Restore power and verify the new surge protector indicator is green.

7.3 Disassembly of Solar Terminals (MC4)

If you need to disconnect MC4 solar terminals, use an MC4 wrench as shown below:

КСНУМКС. Решавање проблема

Проблем	Могући узрок	Решење
No power output from the box.	DC circuit breaker is in the "OFF" or tripped position.	Check the breaker position. If tripped, investigate for overcurrent (e.g., short circuit, overloaded panels) before resetting.
Surge protector indicator is red.	Surge protector has absorbed a voltagе сурге.	Replace the surge protector module immediately to restore protection.
Loose or intermittent connections.	Wiring not properly secured.	Ensure all MC4 connectors are fully seated and locked. For direct wiring, check terminal tightness and cable gland seals.
Water or dust ingress into the enclosure.	Improperly sealed cable glands or damaged enclosure.	Check and tighten all cable glands. Inspect the enclosure for damage; replace if compromised.
