INTRODUCTION
Output filters are used to remove unwanted high frequency content from the output of a
Variable Frequency Drive (VFD). Large voltage spikes are produced when VFDs are used to
drive motors with long cable leads, which can damage motor or cable insulation systems or
motor bearing fluting due to electric discharge. This voltage spike is known as the Reflected
Wave Phenomenon. dV/dt filters extend motor and cable life by reducing the effects of the
Reflected Wave Phenomenon and removing high frequency voltage spikes. dV/dt filters
should be used when motor cables exceed 50 feet and sine wave filters should be used when
motor cables exceed 900 feet.
For additional protection, sine wave filters provide more robust removal of higher frequency
content. As well as providing protection against voltage spikes from reflected waves, a sine
wave filter additional removes lower order harmonic voltage and currents. These benefits are
realized in reduced motor losses (less heating) due to lower eddy currents and magnetic
hysteresis losses in motor steel laminations.

INSTALLATION
3.1 Mounting Your New Output Filter
Proper installation of the unit is important to the performance and normal operating life. It
should be installed in a location free from:
•Corrosive gases or liquids
•Excessive vibration
•Airborne metallic particles
Open type filters should be installed in a panel by a qualified UL 508A panel shop. If wall-
mounted, mount the unit to a solid, non-flammable surface capable of bearing the weight
using the mounting brackets provided with the unit. Floor mounted filters should be attached
to the legs provided and fastened to the floor using concrete anchors or similar hardware.
3.2 Proper Ventilation
To maintain air circulation for adequate cooling, minimum clearance around the unit must be
maintained. Allow six inches on each side and top, and 18 inches below.
Ensure openings are not obstructed. If the unit is mounted in a small room, cabinet, or
building, ensure there is adequate ventilation to provide sufficient cooling for the unit.
3.3 Grounding
•Properly ground the filter according to local electrical code.
•Connect the ground lug to the branch circuit or service ground conductor.
•Resistance to ground measurement must be 25 Ohms or less, according to the
National Electric Code.
3.4 Ground Fault Protection
Devices that utilize power switching electronics like variable frequency drives, emit high
leakage current so ground fault protection devices may not be compatible with a VFD and
output filter.
3.5 Overtemperature Switch
Phase Technologies output filters have an optional self-resetting overtemperature circuit with
a Normally Closed relay that will open when an internal temperature of 180°C is reached (+/-
5°C). An overtemperature relay is highly recommended to shut down the VFD if the internal
temperature reaches an unsafe level to prevent damage to the filter in rare cases when
components overheat due to abnormal operating conditions. If using a Phase Technologies
VFD, the overtemperature relay should be connected to one of the Auxiliary terminals and
the setting AUX SELECT should be set to CLOSED = RUN, OPEN = STOP.

3.6 Installing Power Wiring
WARNING: Input and output wiring to the filter should be performed by authorized
personnel in accordance with the NEC and all local electrical codes and regulations.
CAUTION: Use 600 V wire that is appropriately rated for the current rating of the motor.
Use copper wire with an insulation temperature rating of 90°C or higher. Installations must
comply with all local regulations and the National Electrical Code (NEC).
Verify that the power source is appropriate for the filter being used. Connect the VFD output
(T1, T2, T3 or U, V, W) to the input of the filter (U1, V1, W1). Connect the motor to the output
terminals of the filter (U2, V2, W2). A fused disconnect or circuit breaker should be installed
between the VFD and its power source in accordance with NEC requirements. See Figure
for a system schematic and Table 2 for field wiring terminal specifications.
Figure 4– Filter System Schematic
Table 5 – Field Wiring Power Terminal Specifications
3.7 Startup Checklist
Prior to operation, verify the following:
1. The filter is securely attached to the proper mounting surface
2. All filter ground terminals are properly bonded to earth ground
3. The filter’s input terminals are connected to the output of a VFD and the VFD is
set properly*:
oOutput frequency is less than 90 Hz
oPWM Switching Frequency is 2 – 8 kHz
oOperation mode is Volts per Hertz without DC braking
4. An appropriately rated motor is connected to the output terminals
5. The motor is secured and properly mounted

9 | Page
*Consult Phase Technologies about derate information if desired to operate outside of
these VFD settings.
Note: VFD motor auto-tuning procedures will be greatly affected and likely will result in
inaccurate results. Consult with VFD supplier if auto-tuning is desired with filter installed.
