NOTICE
Risk of exceeding line-to-ground limit. Can cause equipment damage.
The electrically commutated (EC) motors included in 480V CR035 and CR040 units are
suitable for connection to power supplies with 300V or less line to ground potential. Excess
line-to-ground voltage can cause capacitor failure internal to the motors.
• Power supplies such as 480V WYE with solidly grounded neutral have 277V line to ground
and are acceptable.
• Power supplies such as 480V WYE with high resistance (or impedance) ground, 480V delta
without ground or with floating ground, 480V delta with corner ground or 480V delta with
grounded center tap will exceed the 300V line-to-ground limit.
