SAFETY MESSAGES AND WARNINGS
To ensure safe and reliable operation of the Essential Series drives, it is important to
carefully read this manual and to observe all warning labels attached to the unit before
installing. Please follow all instructions exactly and keep this manual with the unit for
quick and easy reference.
Definitions of Warning Signs and Symbols
CAUTION: Indicates a potentially hazardous situation that could result in injury or
damage to the product.
WARNING: Indicates a potentially hazardous situation that could result in serious
injury or death.
HIGH VOLTAGE: The voltage associated with the procedures referenced could
result in serious injury or death. Use caution and follow instructions carefully.
READ THESE WARNINGS BEFORE INSTALLING
OR OPERATING EQUIPMENT!
WARNING: Risk of electric shock. More than one disconnect switch may be
required to de-energize the equipment before servicing.
WARNING: Risk of electric shock. De-energize the unit by disconnecting all
incoming sources of power, then wait 10 minutes for internal charges to dissipate
before servicing the equipment.
HIGH VOLTAGE: This equipment is connected to line voltages that can create a
potentially hazardous situation. Electric shock could result in serious injury or death.
This device should be installed only by trained, licensed, and qualified personnel.
Follow instructions carefully and observe all warnings.
WARNING: This equipment should be installed and serviced by qualified
personnel familiar with the type of equipment and experienced in working with
dangerous voltages.
WARNING: Installation of this equipment must comply with the National Electrical
Code (NEC) and all applicable local codes. Failure to observe and comply with these
codes could result in risk of electric shock, fire, or damage to the equipment.
CAUTION: Circuit breakers, fuses, proper ground circuits, and other safety
equipment and their proper installation are not provided by Phase Technologies, LLC,
and are the responsibility of the end user.

iv | P a g e
CAUTION: Failure to maintain adequate clearance may lead to overheating of
the unit and cause damage or fire.
WARNING: Input power connections should be made by a qualified electrician
into circuit with adequate voltage and current carrying capacity for the model. Branch
circuit protection to the unit should be provided by appropriately sized fuses or a 2-
pole circuit breaker.
CAUTION: Use 600 V vinyl-sheathed wire or equivalent. The voltage drop of the
leads needs to be considered in determining wire size. Voltage drop is dependent on
wire length and gauge. Use only copper conductors.
CAUTION: Wires fastened to the terminal blocks shall be secured by tightening
the terminal screws to a torque value listed in Table 4.
CAUTION: The input wire gauge must be sized to accommodate the single-
phase input current, which will be significantly larger than the three-phase output
current to the load.
CAUTION: The maximum wire gauge for the input terminals is listed in Table 4.
CAUTION: Never allow bare wire to contact metal surfaces.
CAUTION: Never connect AC main power to the output terminals Red, Blk/Yel,
and Blk.
WARNING: Under certain conditions, the motor load may automatically restart
after a trip has stopped it. Make sure power to the drive has been disconnected before
approaching or servicing the equipment. Otherwise, serious injury may occur.

INTRODUCTION
Essential Series variable frequency drives (VFDs) are inverter based devices that provide
speed control for two- and three-wire, single-phase, AC motors. The drives offer advanced
motor control features through an intuitive, easy-to-use interface.
Essential Series Design
The diagrams in Figure 1 and Figure 2 illustrate the basic function of the Essential Series
drives for 2 & 3 wire single phase motors.

INSTALLATION
3.1 Mounting Your New Essential Series VFD
Proper installation of the unit is important to the performance and normal operating life of
the unit. It should be installed in a location free from:
•Corrosive gases or liquids
•Excessive vibration
•Airborne metallic particles
Mount the unit to a solid, non-flammable surface capable of bearing the weight using the
mounting bracket provided on the unit.
3.2 Proper Ventilation
In order 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 air intake and exhaust 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 Source Branch Circuit Protection
Branch circuit protection must be installed in the circuit sourcing the drive. See Table 2 for
recommended circuit breaker sizing, which is based on 125% of the rated input current.
Fuses may be used for circuit protection; consult local electrical code for proper sizing.
Installation of a disconnection means within sight of the drive is recommended.

3.4 Grounding
•Properly ground the drive according to local electrical code.
•Connect the ground lug to the branch circuit or service ground conductor.

3.5 Wire Sizing
Wire size must comply with all NEC and local electrical code requirements. The voltage
drop from the supply to the drive should be limited to 3% to ensure proper starting and
operation of motor loads. Increase the wire gauge to provide adequate voltage to the load.
Ensure the wire gauge is suitable for the terminal block, see Table 4.
Use the following formula to calculate line voltage drop.

See Table 2 for guidelines on fuse and breaker sizes. Installations must comply with all
NEC and local electrical code requirements.
3.6 Connecting the Load
Overload, ground fault, and short circuit protection functions are built into the drive to
protect the load side conductors and motor, as well as the drive itself, from faults.
