Caution: Suitable for use on a circuit capable of delivering not more than the
RMS symmetrical short circuit amperes listed here at rated voltage.
Horsepower
RMS Symmetrical Amperes
1−50 5,000
51−200 10,000
201−400 18,000
401−600 30,000
601−900 42,000
Caution: Disconnect motor leads (T1, T2 and T3) from control before you
perform a “Megger” test on the motor. Failure to disconnect motor
from the control will result in extensive damage to the control. The
control is tested at the factory for high voltage / leakage resistance
as part of Underwriter Laboratory requirements.
Caution: Do not supply any power to the External Trip (motor thermostat)
leads at J1-16 and 17. Power on these leads can damage the
control. Use a dry contact type that requires no external power to
operate.
Caution: Do not connect AC power to the Motor terminals T1, T2 and T3.
Connecting AC power to these terminals may result in damage to
the control.
Caution: Baldor recommends not using “Grounded Leg Delta” transformer
power leads that may create ground loops and degrade system
performance. Instead, we recommend using a four wire Wye.
Caution: Do not use power factor correction capacitors at the input power
lines to the 22H Line Regen control. Installing power factor
correction capacitors may damage the control.
