PowerFlex 700L Frame 1X Drive Installation Instructions – Publication 20L-IN013A-EN-P – June 2009

20

The PowerFlex 700L Frame 1X drive includes input fuses. National and
local industrial safety regulations and/or electrical codes may determine
additional requirements for these installations. Refer to

Table 6

for

recommended fuses/circuit breakers.

Table 6

provides drive ratings (including continuous, 1 minute and 3

second) and recommended AC line input fuse and circuit breaker
information. Both types of short circuit protection are acceptable for UL
and IEC requirements. Sizes listed are the recommended sizes based on
40 °C and the U.S. NEC. Other country, state or local codes may require
different ratings.

Fusing

If fuses are chosen as the desired protection method, refer to the
recommended types listed below. If available amp ratings do not match the
tables provided, the closest fuse rating that exceeds the drive rating should
be chosen.

• IEC – BS88 (British Standard) Parts 1 & 2

(1)

, EN60269-1, Parts 1 & 2,

type gG or equivalent should be used.

• UL – UL Class CC, T, RK1 or J must be used.

Circuit Breakers

The “non-fuse” listings in the following tables include both circuit breakers
(inverse time or instantaneous trip) and 140M Self-Protecting Motor
Starters. If one of these is chosen as the desired protection method, the
following requirements apply.

• IEC and UL – Both types of devices are acceptable for IEC and UL

installations.

(1)

Minimum protection device size is the lowest rated device that supplies maximum protection without nuisance tripping.

(2)

Maximum protection device size is the highest rated device that supplies drive protection. For US NEC, minimum size is 125% of motor FLA. Ratings shown are maximum.

(3)

Circuit Breaker - inverse time breaker. For US NEC, minimum size is 125% of motor FLA. Ratings shown are maximum.

(4)

Motor Circuit Protector - instantaneous trip circuit breaker. For US NEC, minimum size is 125% of motor FLA. Ratings shown are maximum.
