Pre-installation Planning
Verify the Application
HGP Ratings
Make sure that the HGP filter is correct for the application. The voltage ratings of the filter must match
the input voltage rating of the connected drive. The horsepower and current ratings of the filter must be
appropriate for the connected load.
Select a Suitable Location
Environment
Locating the HGP in a suitable environment will help ensure proper performance and a normal
operating life. Refer to the environmental specifications listed in Table marked on the unit's nameplate,
and/or noted on the drawings furnished with the unit.
Warning
Unless specifically labeled as approved for such use, this equipment is not
suitable for use in an explosive atmosphere or in a "Hazardous (Classified)
Location" as defined in article 500 of the National Electrical code.
The unit must be installed in an area where it will not be exposed to:
♦ Direct sunlight
♦ Rain or dripping liquids (unless filter is in a Type 3R enclosure)
♦ Corrosive liquids or gasses
♦ Explosive or combustible gases or dust
♦ Excessive airborne dirt and dust
♦ Excessive vibration
Working Space
Provide sufficient access and working space around the unit to permit ready and safe installation,
operation and maintenance. Make sure that the installation conforms to all working space and
clearance requirements of the National Electrical Code (NEC) and/or any other applicable codes.
Provide sufficient unobstructed space to allow cooling air to flow through the unit.
Mounting an Open Panel Unit
If you are mounting an open panel unit in your own enclosure, you must provide an enclosure that is
adequately sized and ventilated sufficiently to prevent overheating. The rating and dimension tables for
open panel units list the watts of heat loss dissipated by the HGP filter. The maximum temperature of
the air around the HGP filter capacitors, line reactor, and tuning reactor should not exceed 50°C
(122°F).
Power Wiring
When selecting a mounting location for the HGP filter, plan for the routing of the power wiring.
Route the conduit and wiring from the power source to the filter and then to the VFD.
The HGP is provided with internal fuses.
