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.

iii | 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 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 6 and Table 7.
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 6 and Table 7.
CAUTION: Never allow bare wire to contact metal surfaces.
CAUTION: Never connect AC main power to the output terminals U, V, W or 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
SD & 2XD Series variable frequency drives (VFDs) are inverter-based devices that convert single-
phase AC power to three-phase variable frequency output to provide speed control for three-phase AC
motors. The drives offer advanced motor control features through an intuitive, easy to use interface.
The simplified block diagrams below demonstrate how the drive converts the incoming single-phase AC
power to DC, then utilizes an inverter module to generate three-phase variable voltage and frequency
output to control the speed of the primary motor.

2.4 Drive Configuration and Options
SD & 2XD Series drives can be configured with a variety of optional equipment. Please remember to
follow all applicable NEC and local codes to ensure safety and compliance.
CAUTION: When not ordered and installed by Phase Technologies, circuit breakers or fuses,
proper ground circuits, disconnects and other safety equipment and their proper installation are the
responsibility of the end user.
CAUTION: The AC motor load must be connected directly to the main output terminals of the
panel. Do not install relays or disconnect switches between the output terminals and the motor
load.
Fuses or motor overload devices as required by NEC and local safety codes may be installed between
the drive and the motor, however the SD & 2XD Series are equipped with adjustable solid state motor
overload protection.
Output Filters
Some installations may require a load reactor or sine wave filter between the drive and the motor. A
filter reduces harmonics in the PWM output voltage, smoothing the waveforms to reduce vibration in the
motor. Filters also reduce common mode currents in the motor windings that can discharge through
motor bearings, causing pitting and premature motor failure.
Mitigating Electromagnetic Interference (EMI)
Devices that utilize power switching electronics, such as SD & 2XD Series drives, produce high
frequency emissions commonly known as electromagnetic interference (EMI). These emissions can be
conducted on power cables or emitted (radiated) through the air. Conducted and emitted noise can
sometimes interfere with radio signals or sensitive electronic equipment near the installation. The use
of shielded cables and rigid metal conduit on both input and output lines between the converter and the
motor is recommended to help reduce EMI.
2.5 System Configuration Settings
A SD & 2XD Series drives are capable of operating several types of systems, including:
•Simple ON/OFF motor control from the keypad or remote switches
•Digital constant pressure water systems
•Analog constant pressure water systems
•Multiple pump control
Firmware in the drive interprets input signals and other data differently, depending upon the type of
system being operated. It is therefore important to select the appropriate System Configuration setting
either through the Programmable Parameters on the keypad. Detailed information on setting System
Configuration can be found in Section 6.5.

12 | P a g e
INSTALLATION
3.1 Mounting
The drive must be mounted in an upright position with adequate clearance for cooling and maintenance
access. See Section 2.3 for details. The mounting surface must be sturdy and capable of bearing the
weight of the unit. Fasten the unit to the mounting surface using screws or bolts of an appropriate size
through the holes on the mounting brackets. The enclosure can be wall mounted. Brackets for wall
mounting are standard. Lifting hooks are provided on the top of the enclosure.
In order to allow for proper cooling and air circulation around the enclosure, maintain minimum
clearance of 6 inches on the sides and top and 18 inches below. The drives are cooled by fans with
ventilation openings on the side and bottom of the enclosure. The surface around the enclosure should
be of a non-flammable material and clear of obstacles.
Figure 12 –Minimum Clearances
Ambient Temperature Rating
SD & 2XD Series drives are intended for use in ambient temperatures no higher
than 50˚C (122°F).

CAUTION: Failure to maintain
adequate clearance may lead to
overheating of the unit and cause
damage or fire.
NOTE: Outdoor type 3R conduit hubs should be
used with outdoor Type 3R enclosures to maintain
environmental integrity.

13 | P a g e
3.2 Source Branch Circuit Protection
Branch circuit protection must be installed in the circuit sourcing the drive. See Table 3 for
recommended circuit breaker/fuse 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 disconnect
means within sight of the drive is recommended.

3.3 Installing Power Cables
CAUTION: Installations must comply with all NEC and local electrical code requirements.
Connection to input and output power is made on the power terminal block. See Table 4for connection
descriptions and Figure 14 for terminal block locations.
Important Note About Output Filters:
Models that include a sinewave filter have a different power terminal connection configuration. Refer to
Figure 15 for connecting models with output filters.
