While the unit is sealed to IP65 (NEMA 4X) it is advisable to follow the following installation practice where possible
•
Minimise vibration.
•
Do not mount next to strong electrical fields (transformers, power cables)
•
Ensure easy access to interior of the module
•
Install electrical protection device, as the unit is not internally fused.
•
Always ensure the lid is properly fitted and all 4 screws tightened.
•
Always ensure the cable gland is sealing against the cable to maintain the IP (NEMA) rating

The 4 screws for the lid are captive and must be tightened to maintain the seal.
The 4.5mm (0.18”) holes for the mounting screws in the base are directly behind the screws for the lid.
The box must not be drilled as this would invalidate the IP rating
Allow sufficient space at both sides for the cable entry.
The Nylon 66 cable glands are designed for ROUND cables.
The waterproof entry and strain relief will seal to a higher rating than the enclosure.
Cable diameter should be between 4mm (0.16”) and 7mm (0.27”)
