WARNING: The circuits connected to terminals COM, AX1, AX2, SIG, and +V are NOT isolated from
power circuits by Protec ve Separa on in accordance with UL 61800-5-1. Protec ve separa on to
protect these circuits against direct contact is to be supplied by the end user.
Installation
SCCR (Short Circuit Current Ra ng): MGB400 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: 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 MGB400-11 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). Use
18 - 24 AWG wire for logic wiring. Use 14 AWG wire for AC line (L1, L2) and motor (A1, A2) 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
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.
• 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.
• This product does not have internal solid state motor overload protec on. It 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.
Line Input
Connect the AC line power leads to terminals L1 and L2, or to a double-pole, single-throw master
power switch (recommended). The switch should be rated at a minimum of 250 VAC and 200% of
motor current.
Motor
Connect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desired
direc on, power down the drive and reverse these connec ons.

Connections
Speed Poten ometer
Use a 10K ohm, 1/4 W poten ometer for speed control. Connect the counter-clockwise end of the
poten ometer to COM, wiper to SIG, and the clockwise end to +V. If the poten ometer works
inveresly of desired func onality, (i.e. to increase motor speed, you must turn the poten ometer
counterclockwire), power off the drive and swap the COM and +V connec ons. To use an isolated
analog signal instead, connect the signal nega ve (-) to COM and the signal reference (+) to SIG.
Direc on (AX1)
Short terminals AX1 and COM to change the direc on of The motor. If no direc on switch is desired,
leave this connec on open.
Inhibit / Enable (AX2)
Short terminals AX2 and COM to stop the motor. Refer to jumpers 2 and 3 in the Startup sec on to
determine if the switch is normally open or normally closed, and if the motor will regenera vely brake
or coast to a stop. Do not use the inhibit or enable for emergency stopping.
