Installation
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. The switch
contacts must be rated at a minimum of 200% of motor
nameplate current and 250 volts.
Connect the power input leads, field output, external line
fuse(s) and DC motor to the drive’s printed circuit board (PCB)
as shown in Figure 4 (page 12).
Motor connections
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.
Connect a DC motor to PCB terminals A1 and A2 as shown in
Figure 4 (page 12). Ensure that the motor voltage rating is
consistent with the drive’s output voltage.
