Warning
Do not install, remove, or rewire this equipment with power
applied. Failure to heed this warning may result in fire,
explosion, or serious injury.
Circuit potentials are at 115 or 230 VAC above ground. To
prevent the risk of injury or fatality, avoid direct contact with
the printed circuit board or with circuit elements.
Do not disconnect any of the motor leads from the drive
unless power is removed or the drive is disabled. Opening
any one motor lead may destroy the drive.
Use 16 AWG wire for AC line voltage (L1 and L2) and motor
armature (A1 and A2) wiring. Use 18 AWG wire for logic
(inhibit leads or S1, S2 and S3). For the dynamic brake resistor,
use 14 AWG wire for model NRG10–115AC–2Q, or 16 AWG
wire for models NRG05–D240AC–2Q and
NRG02–D240AC–2Q.
