3.2.4 Controller enclosure
The controller enclosure is NEMA 4X/IP66-rated and has a corrosion-resistant finish designed to
withstand corrosive environmental constituents such as salt spray and hydrogen sulfide. Protection
against environmental damage is strongly recommended for outdoor use.
Note: Units that have the Underwriters Laboratories (UL) certification are intended for indoor use only and do not
have a NEMA 4X/IP66 rating.
3.2.5 Controller mounting options
The controller can be mounted to a panel, to a wall or to a vertical or horizontal pipe. A neoprene
sealing gasket is included and can be used to reduce vibration. The gasket can be used as a
template for panel mounting before the inner gasket component is separated.
