Prior to commencing any work on the product, open an
upstream circuit breaker or isolator to ensure that no voltage is
applied to the product otherwise electrical shock may result.
.
For 4 pole breakers, be sure to connect a neutral conductor to
the N-phase pole, otherwise, an overcurrent may hinder the
product from tripping thus resulting in a fire.
.
When connecting cable or busbar to the product, tighten terminal
