Chapter 2 Plan the Kinetix 5700 Drive System Installation

Circuit Breaker/Fuse Selection

The Kinetix 5700 power supplies use internal solid-state motor short-circuit

protection and, when protected by suitable branch circuit protection, are rated

for use on a circuit capable of delivering up to 200,000 A (fuses) and 65,000 A

(circuit breakers).

Refer to Power Wiring Examples

, on page 343, for the wiring diagram.

Table 9 - DC-bus Power Supply UL/CSA Circuit-protection Specifications

Table 10 - Regenerative Bus Supply UL/CSA Circuit-protection Specifications

Table 11 - DC-bus Power Supply IEC (non-UL/CSA) Circuit-protection Specifications

ATTENTION: Do not use circuit protection devices on the output of an AC

drive as an isolating disconnect switch or motor overload device. These

devices are designed to operate on sine wave voltage and the drive’s PWM

waveform does not allow it to operate properly. As a result, damage to the

device occurs.

(1) For applications requiring CSA certification, fuses (Bussmann catalog number 170M1760) must be added to the DC link between the two drive clusters when circuit breakers are used for branch circuit

protection. The DC bus fuses are not required when AC line fuses are used for branch circuit protection.

(2) These Bulletin 140M circuit breakers, when used as self-protected (Type E) devices, and Bulletin 1489 circuit breakers can be used on only WYE power systems (480Y/277V).

(1) Applies when DC-bus voltage regulation is enabled. If DC-bus voltage regulation is not enabled, then the input voltage range is 324….528V AC. For more information on these two modes of

operation, see DC-bus Voltage Regulation

on page 42.

(2) For applications requiring CSA certification, fuses (Bussmann catalog number 170M1760) must be added to the DC link between the two drive clusters when circuit breakers are used for branch circuit

protection. The DC bus fuses are not required when AC line fuses are used for branch circuit protection.
