2-4 General Information MN722
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.
