7.2 INPUT FUSING & DISCONNECT REQUIREMENTS

A circuit breaker or a disconnect switch with fuses must be provided in accordance with the

National Electric Code (NEC) and all local codes. Refer to the following tables for proper

fuse/circuit breaker ratings and wire sizes.

INPUT FUSE & CIRCUIT BREAKER RATINGS

208/240 Vac, 1 phase 208/240 Vac, 3 phase 400/480 Vac, 3 phase 480/590 Vac, 3 phase

NOTE

• Applicable national and local electrical codes take precedence over

recommendations in these tables.

• Use UL Class CC fast-acting, current limiting type fuses. Select fuses

with low I2T values, rated at 200,000 AIC. Recommended fuses are

Bussman KTK-R, JJN, and JJS. Similar fuses with equivalent ratings by

other manufacturers may also be acceptable.

WARNING!

This product can cause a DC current in the protective conductor. Where

a residual current device (RCD) is used for protection in case of direct or

indirect contact, only an RCD of Type B is allowed on the supply side of

this product. Otherwise, another protective measure shall be applied, such

as separation from the environment by double or reinforced insulation, or

isolation from the supply system by a transformer.

Observe the following when using RCDs:

1. Only install the RCD between the supply mains and drive controller.

2. The RCD can be activated by:

• capacitive leakage currents between the cable screens during

operation (especially with long, screened motor cables)

• connecting several drives to the mains at the same time

• additional RFI ﬁlters
