Safety First!
• DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH
POWER APPLIED. Have a qualified electrical technician install, adjust
and service this equipment. Follow the National Electrical Code
and all other applicable electrical and safety codes, including the
provisions of the Occupational Safety and Health Act (OSHA), when
installing equipment.
• Reduce the chance of an electrical fire, shock, or explosion by using
proper grounding techniques, over-current protection, thermal
protection, and enclosure. Follow sound maintenance procedures.
SAFETY WARNINGS
Text in gray boxes denote important safety ps or warnings.
Please read these instrucons carefully before performing any of
the procedures contained in this manual.
It is possible for a drive to run at full speed as a result of a
component failure. Minarik Drives strongly recommends the
installaon of a master switch in the main power input to stop
the drive in an emergency.
Circuit potenals are at 115 VAC 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-metallic screwdriver for adjusng the calibraon trim pots.
Use approved personal protecve equipment and insulated tools
if working on this drive with power applied.

MMRG Series
Most non-regenerave,
variable speed, DC drives
control current ow to a
motor in one direcon.
The direcon of current
ow is the same direcon
as the motor rotaon.
Non-regenerave drives
operate in Quadrant I,
and also in Quadrant III if
the drive is reversible (see
Figure 1). Motors must stop
before reversing direcon.
Unless dynamic braking
is used, non regenerave
drives cannot decelerate a
load faster than coasng to a
lower speed.
Regenerative drives operate
in two addional quadrants:
Quadrant II and Quadrant
IV. In these quadrants,
motor torque is in the
opposite direcon of motor rotaon.
This allows regenerave drives to reverse a motor without contractors
or switches, to control an overhauling load, and to decelerate a load
faster than it would to coast to a lower speed.

Section 4. Installation
Do not install, rewire, or remove this control with input power
applied. Failure to heed this warning may result in re, explosion,
or serious injury. Make sure you read and understand the Safety
Precauons on page i before aempng to install this product.

!
WARNING!
Models MMRG30U, MMRG30U-PCM, MMRG40U, and MMRG40U-PCM
require an addional heat sink when the connuous armature current
is above 5 amps. Use Minarik Drives heat sink kit part number 223-
0159. All other chassis drives have sucient heat sinking in their basic
conguraon. 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mum heat transfer.
Heat Sinking

7
MMRG Series
• Drive components are sensitive to electrostatic discharge. Avoid
direct contact with the circuit board. Hold the drive by the heat sink
only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminals and calibration
trim pots.
• Mount the drive away from heat sources. Operate the drive within
the specified ambient operating temperature range.
• Prevent loose connections by avoiding excessive vibration of the
drive.
• Mount the drive with its board in either a horizontal or vertical
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. Use a star washer beneath
the head of at least one of the mounting screws to penetrate the
anodized surface and to reach bare metal.

If using a remote potenometer with a chassis drive, mount the speed
adjust potenometer through a 0.38 in. (10 mm) hole with the hardware
provided (Figure 5). Install the circular insulang disk between the panel
and the 10K ohm speed adjust potenometer.
Twist the speed adjust potenometer wire to avoid picking up unwanted
electrical noise. If the speed adjust potenometer wires are longer than
18 in. (46 cm), use shielded cable. Keep the speed adjust potenometer
wires separate from power leads (L1, L2, A1, A2).
Speed Adjust Potenometer
Be sure that the potenometer tabs do not make contact with the
potenometer’s body. Grounding the input will cause damage to
the drive.

MMRG Series
• Use 18 - 24 AWG wire for logic wiring. Use 14 - 16 AWG wire for
AC line and motor wiring.
Wiring
Do not install, rewire, or remove this control with input power
applied. Failure to heed this warning may result in re, explosion,
or serious injury.
Circuit potenals are at 115 or 230 VAC above ground. To prevent
the risk of injury or fatality, avoid direct contact with the printed
circuit board or with circuit elements.
Do not disconnect any of the motor leads from the drive unless
power is removed or the drive is disabled. Opening any one
motor lead while the drive is running may destroy 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 signal from remote devices for over temperature
protecon. If motor over protecon is needed in the end-use
product, it needs to be provided by addional equipment in
accordance with NEC standards.


WARNING!

MMRG Series
Shielding Guidelines
As a general rule, Minarik Drives recommends shielding of all conductors.
If it is not praccal to shield power conductors, it is recommended
to shield all logic-level leads. If shielding of all 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 a device on the drive, ground the shield at
the end away from the drive. Do not ground both ends of the shield.
If the drive connues to pick up noise aer grounding the shield, it may
be necessary to add AC line ltering devices, or to mount the drive in a
less noisy environment.
Logic wires from other input devices, such as moon controllers and PLL
velocity controllers, must be separated from power lines in the same
manner as the logic I/O on this drive.
Under no circumstances should power and logic level leads be
bundled together. Induced voltage can cause unpredictable
behavior in any electronic device, including motor controls.

WARNING!

MMRG Series
Chassis drives should be fused for protecon. Use fast acng fuses rated
for 250 VAC or higher and 150% of maximum armature current. Fuse HOT
L1 only when the line voltage is 115 VAC. Fuse both L1 and L2 when the
line fuse is 230 VAC. Table 1 lists the recommended fuse sizes.

Connecons
Do not connect this equipment with power applied. Failure to
heed this warning may result in re, explosion, or serious injury.
Minarik Drives strongly recommends the installaon of a
master power switch in the voltage input line, as shown in
Figure 6 (page 13). The switch contacts should be rated at a
minimum of 200% of motor nameplate current and 250 volts.

!
WARNING!
Power Input
Connect the AC line power leads to terminals L1 and L2. Minarik Drives
recommends the use of a single-throw, double-pole master power
switch. The switch should be rated at a minimum of 250 volts and 200%
of motor current. Refer to Figure 6 on page 13.
Motor
Drives supply motor armature voltage from A1 and A2 terminals. It is
assumed throughout this manual that, when A1 is posive with respect
to A2, the motor will rotate clockwise (CW) while looking at the output
sha protruding from the front of the motor. If the motor does not
spin in the desired direcon, remove power and reverse the A1 and A2
connecons.
Connect a DC motor to terminals A1 and A2 as shown in Figure 6 on page
13. Ensure that the motor voltage rang is consistent with the drive’s
output voltage.
