Setup, Compatibility & Care
Installation should be performed by a qualified electrician in accordance with local wiring regulations. Ensure the mounting surface is flat to maintain the integrity of the enclosure seal.
- Wiring: Use appropriately rated cables for a 25A load and ensure all terminal screws are torqued correctly.
- Glanding: To maintain the IP65 rating, ensure that all cable entry points are sealed with correctly sized, IP-rated cable glands.
- Maintenance: Periodically inspect the handle for smooth operation and check that the enclosure lid remains securely tightened.
- Cleaning: Use a dry or slightly damp cloth to wipe down the exterior. Avoid high-pressure water jets directly on the seal, even though the unit is IP65 rated.
