Installation Procedures
Introduction
The installation fasteners are required when installing the GP unit.
Mount the GP unit in an enclosure that provides a clean, dry, robust and controlled
environment. (IP65, Type 1, Type 4X [Indoor Use Only] or Type 13 Enclosure.)
Installation Requirements
Check that the installation wall or cabinet’s surface is flat, in good condition and has no
jagged edges. Metal reinforcing strips may be attached to the inside of the wall, near the
panel-cut, to increase its rigidity.
Decide on the thickness of the enclosure wall, based on the level of strength required:
1.6...5 mm (0.06...0.2 in.).
Be sure that the surrounding air temperature and the ambient humidity are within their
designated ranges. Surrounding air temperature: 0 to 50 °C (32 to 122 °F) or 0 to 55 °C (32
to 131 °F) (please see the Environment Specifications for your GP unit); ambient humidity:
10 to 90%RH; wet bulb temperature: maximum 39 °C [102 °F]. When installing the GP unit
in a cabinet or enclosure, the surrounding air temperature is the cabinet’s or enclosure’s
internal temperature.
Be sure that heat from surrounding equipment does not cause the GP unit to exceed its
standard operating temperature.
When mounting the GP unit vertically, ensure that the right side of the unit faces up. In other
words, the power connector for DC model, power terminal block for AC model, should be at
the top.
