INSTALLATION:
1. For flush mounting, install sub station in standard 1-gang electrical box with min. 2-1/2" depth.
2. For surface mounting, install sub station in the SBX-1G surface mount enclosure.
3. IMPORTANT! This unit is designed for use in normal weather conditions, and is made to allow for drainage and
evaporation of moisture that naturally gets into it. Do not apply caulking or silicone sealant around the unit
when installing, and do not use weather stripping around the perimeter of the box when mounting. If
sealing the unit is required, the bottom must remain unsealed. Sealing the unit will prevent or inhibit moisture from
dissipating from inside the unit, which may cause corrosion or deterioration to the internal components over time.
Warranty does not cover damage caused by sealing the unit.
