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 line voltage input, as shown
in Figure 7, page 15 (chassis drives only).
The switch
contacts should be rated at a minimum of 200% of motor
nameplate current and 250 volts.
Chassis drives
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.
Connect a DC motor to the drive as shown in Figure 7,
page 15. Ensure that the motor voltage rating is consistent with
the drive’s output voltage.
Power input
For chassis drives, connect the AC line power leads to terminals L1
and L2, or to a double-throw, double-pole master power switch
(recommended) as shown in Figure 7, page 15.
