Physical Installation
Environmental Requirements
The VFD must be installed and used in a controlled environment that meets the following requirements:
The drive electronics are air-cooled. Provide
enough clearance for an airflow around the VFD.
Mount VFD vertically (top up) for proper heat dis-
sipation.
Do not mount VFD in direct sunlight or near other
heat sources.
Do not block cooling vents or airflow with any
panel components or wires.
See minimum mounting clearance table below for
different VFD frame sizes.
Risk of damage to VFD, or malfunction can occur due to improper handling,
installation, or environment.
• Do not mount VFD on equipment with excessive vibration.
• Install in a location where temperature is within the range of product rating.
• Install VFD on a non-combustible surface. The VFD generates heat during normal operation.
• The VFD should be mounted in a Pollution Degree 2 environment. If VFD will be installed in an environment
with a high probability of dust, metallic particles, mists, corrosive gas or other contaminants, the VFD must be
mounted inside the appropriate electrical enclosure with proper NEMA, UL or IP rating and adequate cooling.
• When two or more VFDs are installed in a ventilated enclosure, the cooling system should provide adequate
airflow for all the VFDs. Do not install VFD above another heat source (another VFD, inductive reactors, etc.).

ELECTRICAL INSTALLATION
Mounting the Drive
2
Mounting the Drive
The mounting location should have nearby access to the electrical supply and to the motor wiring.
Use lag screws or bolts appropriate for supporting the weight of the drive.
1. Mount the drive using the mounting holes on the back side of the enclosure.
2. Screws at the top must attach to a solid structure such as a stud or brace.
3. All screw hole locations should be used to ensure the drive is securely mounted.
IMPORTANT: Do not drill holes in the drive.
Electrical Installation
Wiring Guidelines
Risk of bodily injury or damage to drive or other equipment.
• The drive should be mounted on a structure such as a wall or post capable of supporting the weight of the unit.
• Ensure suitable mounting hardware is used when installing back plate and drive on drywall
• Use suitable lifting equipment, in good condition, rated for at least 5 times the weight of the drive.
• The drive must be mounted on a heat-resistant back plate.
Contact with hazardous voltage could result in death or serious injury.
• Disconnect and lock out all power before installing or servicing equipment.
• Always check if DC bus charge LED is off and DC voltage on the terminals DC (+1) and DC (-) is less than 30 VDC
before working on VFD wiring. The DC bus capacitors may hold high-voltage charge for several minutes after
the VFD power is disconnected.
• Connect the motor, the drive, metal plumbing, and all other metal near the motor or cable to the power supply
ground terminal using wire no smaller than motor cable wires.
• All wiring must comply with the National Electrical Code and local codes.
Risk of damage to VFD, or malfunction can occur.
Follow all wire routing and grounding instructions carefully. Inductive currents caused by parallel wiring, or close
proximity between high voltage and control wiring can cause unexpected behaviors.
• Do not run input power and motor wires in the same conduit.
• Do not run motor wires from multiple VFDs in common conduit.
• Do not run control wiring parallel with high voltage wiring.
• Do not run VFD wiring parallel with building or facility wiring.
• Do not install power factor correction capacitors, surge suppressors, or RFI filters to the VFD output.
• The use of any disconnecting device (contactor, disconnect etc.) in motor circuit during VFD run can cause
damage to VFD power components. Stop VFD before opening the motor circuit with disconnect or contactor.
• Do not use aluminum wires for VFD connections.
• Do not leave wire fragments, metal shavings or other metal objects inside the VFD.
• Improper splicing or damage to motor cable insulation may expose the conductor(s) to moisture and can pro-
duce tripping on faults or VFD damage.
• For retrofit application, check the integrity of power and motor leads. This requires measuring the insulation
resistance with a suitable megohm-meter.

ELECTRICAL INSTALLATION
Branch Circuit Protection
3
1. Mount the drive as close as possible to the service entrance panel. Connect directly to the service entrance, not to a sub-panel.
2. Use a dedicated branch circuit for the drive. Verify that the circuit is equipped with a properly-sized circuit breaker or fuse.
3. Separate input power and motor wiring by at least 8 in. (20.3 cm).
4. Cross over other branch circuits and facility wiring at a 90 angle. If necessary to run wires in parallel, separate by at least 8 in.
(20.3 cm).
5. All control wiring—sensors, switches, transducers, etc.—should be in a separate conduit routed individually, not parallel, from
high voltage wiring. In addition, any shielded cables should be properly grounded.
6. Treat Open-Delta power configuration (two-transformer utility bank) as single-phase power and size wiring accordingly.
7. Install a line reactor for VFDs in pump systems with dedicated service transformer to protect VFD from transient power surges
and provide some degree of harmonics distortion mitigation. DC Chokes are included in VFDs rated above 50 HP, which will
not need line reactors.
Branch Circuit Protection
Integral solid-state short circuit protection does not provide branch circuit protection. Branch Circuit Protection must be provided in
accordance with the National Electrical Code (NEC) and applicable local codes; or equivalent as determined by Authorities Having
Jurisdiction (AHJ). The Drive shall be protected by Listed Class J fuses, Listed inverse-time circuit breakers, or Franklin Electric Man-
ual Motor Starters.
Short-circuit current rating (SCCR): The drive is suitable for use on a circuit capable of delivering not more than 100,000 symmetri-
cal amperes (rms) when protected by suitable Class J fuses. Rated fuse current shall be maximum 3 times the motor output full-
load current (FLA) rating. Rated circuit breaker current shall be maximum 2.5 times the motor output FLA rating when using single
phase or polyphase AC motors. For all other motors, refer to NEC Sec 430 and the Franklin Electric Aim Manual. When protected by
a circuit breaker and placed in a panel, drive SCCR is as follows:
Wire Sizing
Size power wire to maintain a voltage drop less than 2% at VFD or motor terminals. For submersible pumping applications, refer to
the Franklin Electric AIM Manual for wire gauge and distance information.
Frame A: Use only copper conductors rated for at least 75 C and 600 V. Use cable with a 90 C rating if ambient environment is
greater than 50 C.
Frame B and above: Use only copper conductors rated for at least 75 C and 600 V. Use cable with a 90 C rating if ambient envi-
ronment is greater than 40C (30 C for models CX-061A-2V, CX-105A-2V, CX-370A-4V, or CX-930A-4V).
For models 460 V and above, install a load (output) reactor to protect motor windings if distance to motor is within 45-100 feet.
Install output dV/dt filter if within 100-1000 feet (800 feet for submersible pumps), or a sine wave filter for greater distances.

Risk of damage to drive, or malfunction can occur.
• Do not connect input power to VFD output terminals U, V, and W otherwise VFD can be damaged.
• Ensure that the system is properly grounded all the way to the service entrance panel. Improper
grounding may result in loss of voltage surge protection and interference filtering.
• Do not connect any wires except dynamic braking resistor to (B1) and (B2) terminals.
• Do not remove the jumper between terminals (+2) and (+1) except for dynamic braking unit or DC
link choke, otherwise the VFD can be damaged.
• When using a general GFCI (Ground Fault Circuit Interrupter), select a current sensor with sensitivity
of 200mA or above and not less than 0.1-second operation time to avoid nuisance tripping.

Control Circuit Connections
Terminal Identification
The control board is divided into 5 groups of terminals and connectors, plus a group of micro switches for individual terminal con-
figurations.
• Always insulate bare control or shield wires with shrink tubing or electrical tape to prevent short circuit.
• The ideal length of stripped wire for control terminals is 5 mm (0.2 in).
1. Analog Inputs/Outputs – These connections are used for transducers, sensors, and control systems such as a BAS, BMS, or
PLC. Use shielded cable with shield connected to the ground terminal. Terminals accept 26~16 AWG (0.13~1.3mm2) wires,
and should be tightened to a torque of 1.73 lb-in (0.19 Nm).
•ACI is a 0-10 VDC or 4-20 mA input, adjustable by micro switch. Set [IO–00] to match the switch setting.
•AVI1 is a 0-10 VDC or 4-20 mA input, adjustable by micro switch. Set [IO–05] to match the switch setting.
•AVI2 is a 0-10VDC input.
When an input source has been connected, select the appropriate terminal in either Auto Speed Ref [SET–07], Hand Speed Ref
[SET–09], or PID F/B Source [SET–18].
•AFM1 & AFM2 are programmable, multi-function analog outputs. Refer to [IO–59] and [IO–61] for options. Each output can
be set by micro switch to 0-10V (min load 5k Ω at 2 mA) or 0/4-20 mA (max load 500 Ω).
•+10V terminal (with common ACM) provides a +10 VDC 50 mA power supply for input devices.
•ACM terminals are the common for analog inputs, outputs and +10 VDC power supply. All ACM terminals are connected
internally.
2. Digital Inputs & RS-485 Communication – These connections provide input for a wide selection of switches or programmable
controls. Use shielded cable or twisted wires and separate from the power and motor wiring and other high voltage circuits.
Terminals accept wire sizes from 24~14 AWG (0.2~1.5mm2), and should be tightened to a torque of 6.9 lb-in (0.78 Nm).
NOTES:
• Digital inputs are configured for NPN (Sink) mode by default, with a jumper across +24 and COM terminals.
• All digital inputs can be re-programmed from Normally Open to Normally Closed. Refer to [IO–46].
• Digital inputs are activated by voltage 11 VDC or greater with an external power supply. Maximum input voltage rating
is 27 VDC at 3.5 mA.
•MI1-MI8 are programmable, multi-function digital inputs that can be used for a variety of switching features with com-
mon terminal DCM. Refer to [IO–21] through [IO–28] for options.
•FWD & REV are dedicated Forward and Reverse run commands. If any other digital input is programmed for FWD or REV,
corresponding dedicated FWD or REV input will be disabled automatically.

•SG+, SG–, & SGND are communication terminals for Modbus RS485 with a shielded cable. Termination resistance is con-
trolled by micro switch. Set the switch to the Down position to connect 120 Ω termination resistance for long distance or for
an electrically noisy environment.
•+24 terminal provides 24 VDC (with DCM common) 50 mA power for digital control circuits and 150 mA for external trans-
ducers.
•COM terminal is a digital inputs common. By default, it is connected by jumper to +24 to configure NPN (Sink) mode.
•DCM is the internal 24 VDC power supply common.
• Earth ground. Use this terminal to connect shield wires.
IMPORTANT: DCM and ACM terminals are isolated from each other and from the ground. Do not connect these terminals
to earth ground, which can cause electrical noise in control circuits and unstable VFD operation.
3. Relay Outputs – These are configurable, multi-function, dry contact relays. Refer to [IO–47] through [IO–49] for options. Termi-
nals accept wire sizes from 24~14 AWG (0.2~1.5mm2), and should be tightened to a torque of 4.3 lb-in (0.49 Nm).
• Relays ratings are 1.25A at 250 VAC, or 3A at 30 VDC.
• RA1-RB1-RC1 is a single-pole, double throw relay. RA1-RC1 is N.O. (normally open), and RB1-RC1 is N.C. (normally closed).
• RA2-RC2 and RA3-RC3 are independent single pole, single throw, normally open relays.
4. Safety Off Inputs – These connections provide emergency stop control from an external system. By default, the inputs are
closed through jumper wires, allowing the drive to run.
5. RJ-45 Sockets – These connections are communication terminals for PLC, Modbus, or BACnet. Use [PLC–23] to set the Com
Type. Then set both Speed Reference and Run Command to RS485. Both RJ-45 sockets are connected internally.

After the initial parameters have been entered, the following default settings should be checked and adjusted to ensure expected
operation. Refer to the “Default Settings Tables” on page 13 for a list of automatically populated settings per application.
1. Auto Speed Ref [SET–07]: Select the source of frequency (speed) setpoint the drive will use when in Auto mode.
• When using one of the analog inputs with an automated BAS, BMS, or PLC system, be sure to configure the terminal for
the correct impedance. Refer to “Terminal Identification” on page 5.
• When using feedback from an analog sensor, such as a transducer, select PID Output. When PID mode is selected, addi-
tional parameters must be verified for setpoints, inputs, and limits.
2. Auto Run Command [SET–08]: Select the source of RUN command when VFD is in Auto Mode—Keypad or external.
3. Hand Speed Ref [SET–09]: Select the source of frequency (speed) setpoint the drive will use when in Hand mode. PID is dis-
abled in Hand mode. Be sure to configure any selected input terminals for the correct impedance.
4. Hand Run Command [SET–10]: Select the source of RUN command when VFD is in Hand Mode—Keypad or external.
5. Low Frequency Limit [SET–13]: The lowest frequency (speed in Hz) allowed by the VFD in any mode.
6. High Frequency Limit [SET–14]: Enter the highest frequency (speed in Hz) allowed by the VFD in any mode.
7. PID Mode [SET–17]: Enables or disables PID control, either direct or inverse.
8. PID Feedback Source [SET–18]: Selects an input terminal for PID Feedback source. Be sure to configure the terminal for the
correct impedance.
9. PID Feedback Unit [SET–19]: Selects a measurement unit for PID feedback.
10. Feedback Max [SET–20]: Enter the maximum reading of the feedback source. This is used to scale the sensor.
11. PID Setpoint [SET–21]: Enter the desired value for the drive to maintain in PID mode, running in Auto. This parameter can also
be changed through keypad control.
12. PID Low Frequency Limit [SET–22]: PID frequency output will be limited to this value.
13. PID High Frequency Limit [SET–23]: PID frequency output will be limited to this value.
