Minarik PCM21000A, User Manual

Page: 17 / 52

11 Installation
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.
Power input
Connect the AC line power leads to terminals L1 and L2, or to a
double-throw, single-pole master power switch (recommended).
Line fuse
Wire an external line fuse between the stop switch (if installed)
and the L1 terminal on terminal board TB501. An additional line
fuse should be installed on L2 if the input voltage is 230 VAC.
The line fuse(s) should be rated at 250 volts and 150 - 200% of
maximum motor nameplate current. Refer to the line fuse chart
on page 8 for fuse ratings.
Warning
Minarik strongly recommends the installation of a master
power switch in the voltage input line, as shown in
Figure 4. The switch contacts should be rated at a minimum
of 200% of motor nameplate current and 250 volts.
