The GPD 205 is a high performance, ultra-compact, pulse width
modulated design which generates a sine-coded, adjustable voltage/frequency three
phase output for complete speed control of any conventional squirrel cage induction
motor. The GPD 205 can maintain a 150% current overload capability for 60
seconds. It will not induce any voltage line notching distortion back to the utility line
and maintains a displacement power factor of not less than 0.98 throughout its
speed range.
When properly installed, operated and maintained, the GPD 205 will provide a
lifetime of service. It is mandatory that the person who operates, inspects, or
maintains this equipment thoroughly read and understand this manual before
proceeding.

The GPD 205 is thoroughly tested at the factory. After
unpacking, verify the part numbers with the purchase order (invoice). Any damages
or shortages evident when the equipment is received must be reported immediately
to the commercial carrier who transported the equipment. Assistance, if required, is
available from your sales representative.
If the drive will be stored after receiving, keep it in its original packaging and store
according to storage temperature specifications on page 62.2.

Location of the GPD 205 (Figures 1-1 & 1-2)
is important to achieve proper performance and normal operating life. The unit
should be installed in an area where it will be protected from:
• Direct sunlight, rain or moisture.
• Corrosive gases or liquids.
• Vibration, airborne dust or metallic particles.
For effective cooling as well as proper maintenance, the GPD 205 must be installed
vertically. There MUST be a MINIMUM 4.0 in. clearance above and below, and a
MINIMUM 1.18 in. clearance on each side.
CAUTION
When mounting units in an enclosure, make sure air entering drive is below
113°F (45°C), by adding a fan or other cooling device if needed. See
environmental specifications on page 62.2.
