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 on page i before
attempting installation.
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.
Warning
Mounting
• Drive components are sensitive to electrostatic fields. Avoid contact with the circuit
board directly. 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.
Installation
250-0251r2.qxd:250-0251r2_readers.qxd 6/6/2007 2:54 PM Page 4
5Installation
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 and the drive is disabled. Opening any one
motor lead may destroy the drive.
Warning
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.

6 Installation
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 of 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 in any
electronic device, including motor controls.
250-0251r2.qxd:250-0251r2_readers.qxd 6/6/2007 2:54 PM Page 6
7Installation
Mount the speed adjust potentiometer through a 0.38 in. (10 mm) hole with the
hardare provided (see Figure 3, page 8). 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 the speed adjust potentiometer wires separate from power
leads (L1, L2, A1, A2).
Be sure that the potentiometer tabs do not make contact with the
potentiometer enclosure. Grounding the input will cause damage to
the drive.
Warning
Speed adjust potentiometer
Line fusing
Protect all Minarik drives with AC line fuses. For XP03-115AC-SL, use fast acting AC line
fuse rated for 8 amps at 250 volts. For all other XP series drives, use fast acting AC line
fuse rated for 3 amps at 250 volts. Fuse only the “hot” side of the AC line (L1).

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 5 (page 13). The
switch contacts should be rated at a minimum of 200% of motor
nameplate current and 250 volts.
Warning
XP-AC-SL series connections
Connect the power input leads, an external line fuse and a DC motor as shown in
Figure 4 (page 11).
Motor
Minarik drives supply voltage from A1 and A2 terminals. It is assumed throughout this
manual that, when A1 is positive with respect to A2, the motor will rotate clockwise
(CW) while looking at the output shaft protruding from the front of the motor. If this is
opposite of the desired rotation, simply reverse the wiring of A1 and A2 with each
other.
Connections
250-0251r2.qxd:250-0251r2_readers.qxd 6/6/2007 2:54 PM Page 9
10 Connections
Connect a DC motor to terminals A1 and A2 as shown in Figure 4 (page 11). Ensure
that the motor voltage and current ratings are consistent with the drive’s output
voltage and current.
Power input
Connect the AC line power leads to terminals L1 and L2, or to a single-throw, doublepole master power switch (recommended).
Line fuse
Wire an external line fuse between the stop switch (if installed) and the L1 terminal as
shown in Figure 4. The XP03-115-SL line fuse should be rated at 250 volts and 8
amps.
