Introduction
6 HSD IOM Manual - Rev. D
Installation Guidelines
Mounting
Select a mounting area that will allow adequate cooling air flow and maintenance access.
Wiring
Cable Entry Locations
The enclosed HSD filters are not provided with enclosure wiring knockouts. A location can be selected
at the time of installation. Typical or recommended cable entry locations are shown in the drawings
section of this manual.
Field Wiring Connection Terminals
Compression type terminals (Lug Options) are available for 480V HSD filters 75HP and above and 600V
HSD filters 100HP and above. The wire size capacity ranges and tightening torques for all field wiring
connections are listed in Table 1.
Grounding
The HSD panel equipment-grounding lug must be connected to the ground of the wiring system. The
equipment-grounding connection must conform to the requirements of the National Electrical Code
(NEC) and/or any other codes that apply to the installation site. The ground connection must be made
using a wire conductor. Metallic conduit is not a suitable grounding conductor. The integrity of all
ground connections should be periodically checked.
Power Wiring
Caution
Use copper wire that is appropriate for the voltage and current rating of the
equipment. The wire selection must conform to the requirements of the
National Electrical Code (NEC) and/or other applicable electrical codes.
Use copper wire with an insulation temperature rating of 90°C or higher.
Connect three-phase power of the appropriate voltage and current capacity to the circuit
protective device to the HSD input power terminals. Use copper wire with an insulation
temperature rating of 90°C or higher.
Note: in large units, the input power conductors are connected directly to the input terminals on
the line reactors.
Connect the output terminals of the HSD to the input power terminals of the VFD.
Note: in large units, the output power conductors are connected directly to the output terminals
on the line reactors. Refer to the VFD installation instructions for additional information.
