Mounting Considerations

M2 Digital Meters have three mounting methods: surface mount, flat panel mount, and 360 panel mount. When surface mounted per instructions the
unit face is waterproof to IP66. Flat panel and 360 panel mounting systems are not waterproof. The unit should not be flat panel or 360 panel mounted
if used in an exposed location. For all mountings, the back of the unit is not waterproof and must be kept dry.
