Circuit protection must be installed before AC drive. See section 2.3
of the user manual for the appropriate circuit breaker for your drive.
AC Drive and motor-side ground. Improper grounding could result
in serious injury or death from contacting the motor case.
Grounding impedance: 240V class - less than 100Ω,
480V class - less than 10Ω
Do not connect any other terminal to ground.
Only the ground terminal with the symbol should be
connected to ground.
MAIN CIRCUIT POWER SUPPLY TERMINALS MUST BE
CORRECTLY WIRED
Single Phase Input: L1(L) and L3(N)
Three Phase Input: L1(L), L2, and L3(N)
MOTOR CONNECTION ONLY: T1, T2, T3

WARNING
Depending on the AC drive model, terminal labels and layouts may be
slightly different. Please see table below for details on terminal labels
and their functions.
NOTE
1: Only 480V 1-3HP units have a built-in braking
transistor. The braking resistor can be
connected directly between P and BR. All
others do not have external braking
capabilities.
2: Grounding impedance: 240V class - less than
100Ω, 480V class - less than 10Ω
Greater impedance indicates a poor ground.
