Installation

SCCR (Short Circuit Current Ra�ng): MGC403 series drives are suitable for use on a circuit capable of
delivering not more than 5,000 RMS symmetrical amperes, 115/230 volts maximum.
Branch Circuit Protec�on: The MGC403 has integral solid state circuit protec�on, this does not
provide branch circuit protec�on. Branch circuit protec�on must be provided in accordance with the
Na�onal Electrical Code and any addi�onal local codes. Class J, Class CC, or Class T fuses are to be
rated with a minimum of 230 VAC and a maximum current ra�ng of 40 amps. Circuit breakers are to
be rated at a minimum of 230 VAC with a maximum current ra�ng of 30 amps.
Moun�ng
• Install the drive in a Pollu�on Degree 2 environment only.
• Drive components are sensi�ve to electrosta�c discharge. Avoid direct contact with the circuit
• board. Hold the drive by the chassis only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminal block and calibra�on trim pots.
• Mount the drive away from heat sources. Operate the drive within the specified ambient opera�ng
• temperature range.
• Prevent loose connec�ons by avoiding excessive vibra�on of the drive.
• Mount the drive with its board in either a horizontal or ver�cal plane. Eight 0.19" (5 mm) wide slots
• in the chassis accept #8 pan head screws. Fasten either the large base or the narrow flange of the
• chassis to the subplate.
• The chassis should be earth grounded. Connect the ground to the green screw on the chassis.
Heat Sinking: The MGC403-11 requires an addi�onal heat sink when the con�nuous armature current
is above 8 amps. Use heat sink kit part number 223-0159. Use a thermally conduc�ve heat sink
compound (such as Dow Corning 340® Heat Sink Compound) between the chassis and the heat sink
surface for op�mal heat transfer.
Wiring: 60°C wire was used in UL evalua�on of the power wiring terminals (L1, L2, A1, A2, F1, F2). Use
18 - 24 AWG wire for logic wiring. Use 14 AWG wire for AC line (L1, L2) and motor (A1, A2, F1, F2)

wiring.

Shielding Guidelines: As a general rule, it is recommended to shield all conductors. If it is not prac�cal
to shield power conductors, it is recommended to shield all logic-level leads. If shielding of logic-level
leads is not prac�cal, the user should twist all logic leads with themselves to minimize induced noise.
Refer to the user's manual for details on earth grounding shielded wires and filtering.

READ ALL SAFETY WARNINGS BEFORE INSTALLING THIS EQUIPMENT
Continuous
Armature
• DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a
Armature Horsepower
• qualified electrical technician install, adjust and service this equipment. Follow the Na�onal
Current (Amps) Range
• Electrical Code and all other applicable electrical and safety codes, including the provisions of the
1/50 - 1/8
• Occupa�onal Safety and Health Act (OSHA), when installing equipment.
1.5
1/25 - 1/4 • Circuit poten�als are at 115 or 230 VAC above earth ground. Avoid direct contact with the printed
• circuit board or with circuit elements to prevent the risk of serious injury or fatality. Use a non-
1/8 - 1
11.0*
• metallic screwdriver for adjus�ng the calibra�on trim pots. Use approved personal protec�on
1/4 - 2
• equipment and insulated tools if working on this drive with power applied.
• Reduce the chance of an electrical fire, shock, or explosion by using proper grounding, over-current
• protec�on, thermal protec�on, and enclosure. Follow sound maintenance procedures.
• ACE strongly recommends the installa�on of a master power switch in the line voltage input. The
• switch contacts should be rated for 250 VAC and 200% of motor nameplate current.
• Removing AC line power is the only acceptable method for emergency stopping. Do not use
• regenera�ve braking, decelera�ng to minimum speed, or coas�ng to a stop for emergency stopping.
• They may not stop a drive that is malfunc�oning. Removing AC line power is the only acceptable
• method for emergency stopping.
• Line star�ng and stopping (applying and removing AC line voltage) is recommended for infrequent
• star�ng and stopping of a drive only. Regenera�ve braking, decelera�ng to minimum speed, or
• coas�ng to a stop is recommended for frequent starts and stops. Frequent star�ng and stopping can
• produce high torque. This may cause damage to motors.
• Do not disconnect any of the motor leads from the drive unless power is removed or the drive is
• disabled. Opening any one lead while the drive is running may destroy the drive.
• The field output is for shunt wound motors only. Do not make any connec�ons to F1 and F2 when
• using a permanent magnet motor.
...........0 to ± 10 VDC; 4 - 20 mA
• Under no circumstances should power and logic level wires be bundled together.
• Be sure poten�ometer tabs do no make contact with the poten�ometer's body. Grounding the
• input will cause damage to the drive.
• This product does not contain speed sensi�ve overload protec�on, thermal memory reten�on, or
• provisions to receive and act upon signals from remote devices for over temperature protec�on. If
• motor protec�on is needed in the end-use product, it needs to be provided by addi�onal equipment
• in accordance with NEC standards.
Status 1 LED (STAT): Green LED on Top Board
SOLID: Normal opera�on
1 FLASH: The drive is disabled. Refer to DIP Switches 6 and 7 and terminal EN.
2 FLASHES: The drive is set for Auto Restart Preven�on Mode and has experienced a fault.
2 FLASHES: Cycle the AC power, enable, or inhibit.
2 FLASHES: Refer to DIP Switch 4.
3 FLASHES: The Opera�ng Mode was changed and the drive power must be cycled.
4 FLASHES: The drive tripped for Motor Overload Protec�on.
5 OR MORE FLASHES: Contact the factory.
Limit LED (LIMIT): Red LED on Top Board
SOLID: The drive is in current limit. The motor is asking for more current than what the drive
SOLID: is set for. Refer to FWDCL and REVCL trim pots.
FLASHING: The drive is in Motor Overload Protec�on Calibra�on Mode.
Status 2 LED (STATUS): Green LED on Bo�om Board
SOLID: Normal opera�on
1 FLASH: The power board is not receiving a run command from the top board.
2 OR MORE FLASHES: Contact the factory.

Setup

POWER JUMPERS
Feedback Select
If using tachogenerator feedback, set the feedback select jumper for TACH. If no tachogenerator
feedback is used, set the feedback select jumper to A90 if using a 90 VDC motor or to A180 if using a
180 VDC motor.
Place the jumper on A180 if using a 180 VDC motor with no tach feedback.
Place the jumper on A90 if using a 90 VDC motor with no tach feedback.
Place the jumer on TACH if using tach feedback.
Motor Current Select
Set the jumper for the lowest current base value that is s�ll larger than the full load amperage ra�ng
of the motor. This adjusts the scaling of the current limit trim pots to allow for as small a range on the
trim pot as possible for finer tuning.
Place the jumper on 10A if using a motor between 5 and 10 amps.
10A
5A Place the jumper on 5 A if using a motor between 2.5 and 5 amps.
2.5A Place the jumper on 2.5A if using a motor between 1.7 and 2.5 amps.
1.7A
Place the jumper on 1.7A if using a motor smaller than 1.7 amps.
