(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.
(5) Installations with high fault current due to large supply mains may require a type D circuit breaker.
(6) Thermomagnetic type breakers preferred.
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
