12 Installation
Connections
Power, fuse and motor connections
Connect the power input leads, an external line fuse and a DC
motor to TB501 on the drive’s printed circuit board (PCB) as
shown in Figure 5, page 14.
Motor
Minarik drives supply motor 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.
Warning
Do not install, remove, or rewire this equipment with
power applied. Failure to follow this warning may result in
fire, explosion, or serious injury.
Minarik strongly recommends the installation of a master
power switch in the voltage input line, as shown in
Figure 5, page 14. The switch contacts should be rated at a
minimum of 200% of motor nameplate current and 250
volts.
