Connections
Do not connect this equipment with power applied.
Failure to
heed this warning may result in fire, explosion, or serious injury.
Minarik Drives strongly recommends the installation of a
master power switch in the voltage input line, as shown in
Figure 6 (page 13).
The switch contacts should be rated at a
minimum of 200% of motor nameplate current and 250 volts.
!
WARNING!
Power Input
Connect the AC line power leads to terminals L1 and L2. Minarik Drives
recommends the use of a single-throw, double-pole master power
switch. The switch should be rated at a minimum of 250 volts and 200%
of motor current. Refer to Figure 6 on page 13.
Motor
Drives supply motor armature 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 the motor does not
spin in the desired direction, remove power and reverse the A1 and A2
connections.
Connect a DC motor to terminals A1 and A2 as shown in Figure 6 on page
13. Ensure that the motor voltage rating is consistent with the drive’s
output voltage.
