How to use

To install the Hensel RK 0203 T, first ensure the power supply is disconnected. Mount the box securely to a flat surface using the provided mounting points. Feed the cables through the appropriate cable entries, ensuring that the seals are properly seated to maintain the IP66 rating. Strip the insulation from the conductors and insert them into the terminal block, tightening the screws to the manufacturer's recommended torque. Once all connections are verified, secure the lid firmly to ensure the enclosure is sealed against environmental elements.

What to consider before purchase

• Verify that the 2.5mm2 conductor size meets your specific circuit requirements.
• Ensure the cable entry points are compatible with your cable glands or conduit systems.
• Confirm that the installation environment does not exceed the IP66 protection limits.

Usage recommendations

Always ensure that the lid is tightened correctly after installation to maintain the integrity of the IP66 seal. If using aluminum conductors, ensure that the terminal block is properly prepared according to local electrical standards to prevent oxidation and ensure a long-lasting connection.
