Connections
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, as shown
in Figure 1 (page 3). The switch contacts should be rated
at a minimum of 200% of motor nameplate current and
250 volts.
Power and line fusing connections
• Use 18-24 AWG wire for speed adjust potentiometer
wiring. Use 14–16 AWG wire for AC line (L1 and L2)
and motor (A1 and A2) wiring. Use 18 AWG wire for
field (F1 and F2) wire.
