Installation
Prerequisites
CAUTION:
On installation of a SED2 after extended
storage, see the Extended Storage:
Conditioning of Capacitors section in the
SED2 VFD Startup, Operation, and
Maintenance Manual (Document Number
125-3201). If capacitors are not properly
recharged, catastrophic damage to the
drive can result.
Install the SED2 in a climate-controlled environment
that is free of moisture and conductive
contaminants, such as condensation and dust. The
air entering the unit for ventilation must be clean and
free of corrosive materials. The ambient temperature
must be between 14°F and 104°F (–10°C and 40°C)
and the relative humidity must be 0% to 95%
non-condensing. Do not mount unit in direct sunlight.
