Mount the ERC-2 to a wall or any flat surface using the three holes in
the metal case (models ERC-2 - x11xxx and x21xxx) or the 4 holes in
the plastic support for the ERC-2 - 131xxx, 151xxx, and 351xxx models.
The control’s components are not position sensitive, but should be
mounted so they can be easily wired and adjusted. The models that do
not come in a metal case must be mounted inside an enclosure (NEMA
1 type or better). Avoid excessive conditions of moisture, dirt, dust and
any corrosive atmosphere.
