(1) Observe the applicable local regulations
(2) Pulse-current or universal-current sensitive earth leakage circuit breaker
(3) UL Class CC or T fast-acting current-limiting type fuses, 200,000 AIC, required. Bussman KTK-R,
JJN, JJS or equivalent
(4) Connection without end ferrules or with attached pin end connectors
Observe the following when using E.l.c.b:
• Installation of E.l.c.b only between supplying mains and controller.
• The E.l.c.b can be activated by:
− capacitive leakage currents between the cable screens during operation (especially with
long, screened motor cables).
− connecting several controllers to the mains at the same time.
− RFI filters
