American Power Conversion PMH3XLM Surge Protection Devices are designed for use on the load side

Storage

The unit should be stored in a clean, dry environment. Storage temperature is -40oC (-40oF) to +60o C (+140o F). Avoid exposing the unit to areas of high condensation. All of the packaging materials should be left intact until the unit is ready for installation. If the unit has been stored for an extended period of time, it may be necessary to clean the unit and make a complete inspection of the unit prior to having it installed and placing it into service.

LOCATION CONSIDERATIONS

Environment

The SPD is designed to operate indoors in an ambient temperature range of -40oC (-40oF) to +60o C (+140o F) with a relative humidity of 0% to 95% non-condensing. The standard unit is in a Type 1 industrial use enclosure intended for indoor use. Primarily, it provides a degree of protection against contact with the enclosed equipment. It should not be installed in areas with excessive dust, flammable materials, corrosive vapors or explosive atmospheres.

Audible Noise

The unit background noise is negligible, and does not restrict the location of the installation.

Mounting and Cabinet Data

For planning purposes, the PMH3XLM is designed to be wall mounted. The unit size is as shown in Figure 1, and weighs 17 pounds (7.71 kg). Shipping weight is 19 pounds (8.618 kg).
