2.3.1 - Terminal box (TB) of FFB brake motors
The standard terminal box of the FFB brake motor has holes
on sides 1 and 3:
- frame size 71 to 132 S, SU: 4 x ISO M20 x 1.5
- frame size 132 SM, M, MU to 180: 2 x ISO M25 x 1.5 and
2 x ISO M20 x 1.5 (6 with accessories, wires spotted)
These holes are closed with threaded plugs.
An optional cable gland kit is available, otherwise procure the
necessary cable glands in accordance with the tables below.

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
hand.
