Safety Warnings

• This symbol  denotes an important safety tip or warning.

Please read these instructions carefully before performing
any of the procedures contained in this manual.

• 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

proper grounding, over-current protection, thermal protection,
and enclosure. Follow sound maintenance procedures.

It is possible for a drive to run at full speed as a result of
a component failure. Minarik strongly recommends the

installation of a master switch in the main power input to
stop the drive in an emergency.

Circuit potentials are at 115 V AC 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 adjusting the
calibration trimpots. Use approved personal protective
equipment and insulated tools if working on this drive with
power applied.

Mounting

•

Drive components are sensitive to electrostatic fields. Avoid

direct contact with the circuit board. Hold drive by the chassis

only.

• Protect the drive from dirt, moisture, and accidental contact.

Provide sufficient room for access to the terminal block and

calibration trimpots.

• 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 drive with its board in either a horizontal or vertical

plane. Six 0.19 in. (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 must be earth grounded. Use a star washer beneath

the head of at least one of the mounting screws to penetrate the

anodized chassis surface and to reach bare metal.

Installation

Warning

Do not install, rewire, or remove this control with input
power applied. Doing so may cause fire or serious injury.

Make sure you have read and understood the Safety
Warnings before attempting installation.



5Installation

Wiring

• Use 18-24 AWG wire for speed adjust potentiometer wiring.
Use 14–16 AWG wire for AC line (L1, L2) and motor (A1 and
A2) wiring.

Warning

Do not install, remove, or rewire this equipment with power
applied. Failure to heed this warning may result in fire,
explosion, or serious injury.

Circuit potentials 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 may destroy the drive.

Shielding guidelines

As a general rule, Minarik recommends shielding of all
conductors.

If it is not practical to shield power conductors, Minarik
recommends shielding all logic-level leads. If shielding logic
leads is not practical, 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 continues to pick up noise after grounding the shield,
it may be necessary to add AC line filtering devices, or to mount
the drive in a less noisy environment.

Logic wires from other input devices, such as motion controllers
and PLL velocity controllers, must be separated from power lines
in the same manner as the logic I/O on this drive.

Warning

Under no circumstances should power and logic leads be
bundled together. Induced voltage can cause unpredictable
behavior any electronic device, including motor controls.



7Installation

Heat sinking

PCM2x000-series drives require an additional heat sink when the
continuous armature current is above 5 ADC. Use Minarik® part
number 223–0159. All other chassis drives have sufficient heat
sinking in their basic configurations.

Apply a thermally conductive heat sink compound (such as Dow
Corning® 340 Heat Sink Compound) between the drive chassis
and heat sink surface for optimum heat transfer.

Line fusing

Minarik drives require an external fuse for protection. Use fast
acting fuses rated for 250 VAC or higher, and approximately
150% of the maximum armature current. Fuse both L1 and L2
when the line voltage is 230 VAC. Fuse blocks are included on
cased drives only.

Table 1 (page 8) lists the recommended replacement line fuse
sizes.

Minarik Corporation offers two fuse kits: part number 050–0066
(1–5A Fuse Kit) and 050–0071 (5–15A Fuse Kit).

Speed adjust potentiometer

9Installation

Mount the speed adjust potentiometer through a 0.38 in. (10 mm)
hole with the hardware provided (Figure 3). Install the circular
insulating disk between the panel and the 10K ohm speed adjust
potentiometer. Twist the speed adjust potentiometer wire to avoid
picking up unwanted electrical noise. If speed adjust
potentiometer wires are longer than 18 in. (457 mm), use shielded
cable. Keep speed adjust potentiometer wires separate from power
leads (L1, L2, A1, A2).

Warning

Be sure that the potentiometer tabs do not make contact with
the potentiometer enclosure. Grounding the input will cause
damage to the drive.

Connections

Warning

Do not connect this equipment with power applied.

Failure to heed this directive may result in fire or serious
injury.

Minarik strongly recommends the installation of a master
power switch in the voltage input line, as shown in
Figure 4 (page 13) or Figure 5 (page 14). The switch

contacts should be rated at a minimum of 200% of motor
nameplate current and 250 volts.

Power, fuse and motor connections

If you use a PCM2x000A-series drive, connect the power input
leads, an external line fuse and a DC motor to the drive’s printed
circuit board (PCB) as shown in Figure 4, page 13.

If you use a PCM2x000C-series drive, refer to Figure 5 (page 14).

Motor

Connect a DC motor to PCB terminals A1 and A2 as shown in
Figure 4. Ensure that the motor voltage rating is consistent

with the drive’s output voltage.
