How to use

Prepare the installation location in the cabinet and ensure compatible mounting points for a 90×210 mm housing. Open the enclosure as required to fit switchgear, terminal blocks or protection devices, and secure components using appropriate screws and mounting accessories compatible with polyamide housings. Make electrical connections following local wiring standards and verify that installed devices do not exceed the enclosure's 250 A support limit. Close and secure the enclosure, ensuring gaskets or seals (if present) are correctly positioned to maintain protection.

Usage recommendations

Install the enclosure in dry, ventilated indoor areas and avoid exposure to prolonged UV radiation or aggressive chemicals. Confirm compatibility of mounted components with polyamide mounting surfaces and follow electrical safety rules and local standards when performing connections and commissioning.
