WIRING DIAGRAMS

The terminal box is watertight once the cable glands have been
fitted and each cable gland is tightened on the cable according
to its cable size.
Adapt the cable gland and its reducer if present to the diameter
of the cable being used.
In order to maintain the brake motor's original IP55 protection,
it is essential to ensure the cable gland provides a total seal by
tightening it correctly (so that it cannot be unscrewed by hand).
When there are several cable glands and some are not being
used, ensure that they are always covered (threaded plugs)
and tighten them so that they also cannot be unscrewed by
> 2
hand.
