13 Installation
With line voltage disconnected, connect a DC motor armature to
PCB terminals A1 and A2 as shown in Figure 5. Ensure that the
motor voltage rating is consistent with the drive’s output
voltage.
Power input
Connect the AC line power leads to TB501 terminals L1 and L2,
or to a single-throw, double-pole master power switch
(recommended).
Line fuse
With line voltage disconnected, 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 240 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 10 for fuse ratings.
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.
