25 South Street, Hopkinton, MA 01748
This guide contains installation and applications information for the
MultiPro MC Dual Servo Automation Controller.
You program the MultiPro MC Dual Servo controller using CTCs state
programming language, uickstep for Windows. Using either an
RS-232 interface, you can run all programming and diagnostic functions
for the controller from your PC, as well as using them as a computer
communications port.

Dimensions and Mounting Instructions for the MultiPro Controllers
The MultiPro has mounting ears, allowing it to be easily mounted to a flat surface (for
example, an NEMA-rated electrical enclosure) with four mounting bolts. You should
follow the guidelines described in this installation guide to ensure a successful design.
Mounting Considerations
When selecting a mounting location for the controller, care should be taken to provide
protection against various environmental factors:
The controller should not be exposed to flying metal chips (be careful during instal-
lation and subsequent machine construction work.), conductive dusts, liquids or
condensing humidity. In environments where these hazards may be present, the
controller should be housed in an NEMA 4 or NEMA 12 rated enclosure, as appro-
priate.
The controller is not intended for mounting in an environment requiring explosion
proof practices.
If possible, the controller should be mounted physically distant from devices produc-
ing electromagnetic interference (EMI) or radio frequency interference (RFI). This
includes motor starters, relays, large power transformers, ultrasonic welding appara-
tus, etc.

MultiPro MC Dual Servo Power Connections
Connecting DC ower
The MultiPro MC Dual Servo contains an internal power supply which provides a +5
VDC isolated voltage for the operation of the controller.
The controllers power supply requires 24 VDC for proper operation. Power is applied
to the controller via the power connector on the top of the controller. The controllers
power system derives its operating voltage from the external 24 volt supply.

The Importance of roper Grounding
As with any electronic equipment, the controllers ground should follow a direct, low-
impedance path to the plants power source. If possible, this path should not be share by
any machinery which injects a large amount of electrical noise into the ground.
For further consideration regarding noise protection, refer to the Application Note,
Re ucing Noise Susceptibility. Application notes may be obtained at no charge from
your distributor or directly from CTC.
