Correcting Phase Polarity
This sub-section is only provided for troubleshoot-
ing 3-phase power connections. If you discover
during the test run that the machine will not oper-
ate, or that the motor runs backwards, the power
supply connection may be wired "out of phase,"
meaning that the polarity is incorrect as wired.
This is a common situation with 3-phase power,
and it is easy to correct.
To correct polarity of incoming power supply
connection:
1. DISCONNECT MACHINE FROM POWER!
2. Open lower left access and electrical box
doors, and swap wires connected to " R" and
"
S" terminals (see Figure 43).
Figure 43. Location of "R" and "S" terminals.
R and S
Terminals
Figure 41. Connecting power to machine.
Move the disconnect switch handle to the ON
position, as illustrated below. The machine is now
connected to the power source.
Connecting to Power Source
Figure 42. Disconnecting power from machine.
Move the disconnect switch handle to the OFF
position, as illustrated below. The machine is now
disconnected from the power source.
Note: Lock the switch in the OFF position to
restrict others from starting the machine.
Disconnecting from Power Source
— Make sure wires have enough slack inside
electrical box so they are not pulled tight
or stretched.
5. Close electrical box and lower left access
door, then proceed to Test Run (refer to
Page 29).
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.
4. Connect ground wire to bottom of ground
terminal "E", then connect incoming power
wires to bottom "R", "S", and "T" terminals
shown in
Figure 40. If using a phase con-
verter, connect wild wire to "T" terminal.
