Installation 3

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 I

T 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
