This symbol m denotes an important safety tip or warning. Please read these instruc-
•
tions carefully before performing any of the procedures contained in this manual.
DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have
•
a qualied 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 re, shock, or explosion by proper grounding,
•
over-current protection, thermal protection, and enclosure. Follow sound maintenance
procedures.
m WARNING
It is possible for a drive to run at full speed as a result of a component failure. Mi-
narik 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 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 adjusting the calibration trimpots.
Use insulated tools if working on this drive with power applied.

Overview
The following is an overview of the steps taken to set up a MC10 Series control. For more
detailed installation information, read the Installation and Calibration sections of this
manual.
Mount the control using the 4 slotted holes on the heat sink. The slotted holes are
1.
0.19 inches [5 mm] (see Figure 1).
Remove the plastic cover by unscrewing the 6 screws on the front cover and 5 screws
2.
on the bottom plate. NOTE: Do not remove the 3 screws securing the bottom plate to
the heatsink.
Change the line fuse if necessary. If the horsepower rating of the motor being used is
3.
less than the maximum HP rating of the drive, the line fuse may have to be replaced
with a lower rated one.
Wire the control through the conduit holes, or optional aluminum hardware. NOTE: Do
4.
not connect the control while power is applied.
Assure that settings on voltage switches are correct (SW501 & SW502).
5.
Apply power to the drive.
6.
Calibrate the trimmer pots, if necessary.
7.
Re-install the plastic cover.

Installation
Mounting
MC10 Series drives may be vertically wall mounted using the four 0.19 inch (5 mm) slotted
holes on the attached heat sink (see Figure 1, Page 2). For motor loads less than 5 ADC,
the drive may be bench mounted horizontally, or operated without mounting.
Removing the Plastic Cover
Connections, calibration, and other settings must be made internally. After mounting, use
the following procedure to remove the plastic cover and congure the control:
Remove the six (6) phillips screws on the front cover. NOTE: The two shorter
1.
screws (#6 - 32 x 2 ½) are for the two lower holes on the front of the
cover (see Figure 2, page 6).
Remove the ve (5) phillips screws on the bottom plate (see FIgure 2, page 6). NOTE:
2.
DO NOT remove the 3 screws securing the bottom plate to the heatsink.
Line fusing
Line fuses are preinstalled on all MC10 Series drives. If the current rating of the motor be-
ing used is less than the maximum current rating of the drive, the line fuse may have to be
replaced with a lower rated one. Refer to Table 1 for recommended line fuse sizes.

Do not connect this equipment with power applied. Failure to heed this directive may
result in re or serious injury.
Install conduit hardware through the two 0.73 inch (18.5 mm) conduit holes or by
1.
using optional aluminum cord connectors (Part # 155-0081) attached to the line seal
plate on the bottom of the case.
Connect external wiring to the terminal block as shown in Figure 3, page 7.
