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: 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.
• Components are sensi�ve to electrosta�c discharge. Avoid direct contact with the circuit board. Hold
the drive by the chassis only.
• Protect from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminal block and calibra�on trim pots.
• Mount away from heat sources. Operate within the surrounding air temperature range.
• Prevent loose connec�ons by avoiding excessive vibra�on.
• 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. It
may be necessary to earth ground the shielded cable. If noise is produced by devices other than the
drive, ground the shield at the drive end. If noise is generated by the drive, ground the shield at the end
away from the drive. Do not ground both ends of the shield.

READ ALL SAFETY WARNINGS BEFORE INSTALLING THIS EQUIPMENT
Continuous Armature
• DO NOT INSTALL, REMOVE OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a qualified
Armature Horsepower
electrical technician install, adjust and service this equipment. Follow the Na�onal Electrical Code
Range
and all other applicable electrical and safety codes, including the provisions of the Occupa�onal
1/50 - 1/8 Safety and Health Act (OSHA), when installing equipment.
1.5
• Circuit poten�als are at 115 or 230 VAC above earth ground. Avoid direct contact with the printed
1/25 - 1/4
circuit board or with circuit elements to prevent the risk of serious injury or fatality. Use approved
1/8 - 1
personal protec�on equipment and insulated tools if working with power applied. Use a non-
11.0*
1/4 - 2
metallic screwdriver for adjus�ng the calibra�on trim pots.
• Reduce the chance of an electrical fire, shock, or explosion by using proper grounding techniques,
over-current protec�on, thermal protec�on and enclosure. Follow sound maintenance procedures.
• It is strongly recommended to install 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
braking, decelera�ng, or coas�ng to a stop for emergency stopping. They may not stop a drive that is
malfunc�oning.
• Line star�ng and stopping (applying and removing AC line voltage) is recommended for infrequent
star�ng and stopping of a drive only. 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 damage the drive.
• Under no circumstances should power and logic level wires be bundled together.
• Be sure poten�ometer tabs do not make contact with the poten�ometer's body. Grounding the
input may cause damage to the drive.
• 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 / Analog Signal
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 counterclock-
wire), 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.
