2.6 - Mains/drive connection
This section only applies to CPLS motors
without
the CPS system (optional).
For motors equipped with this system, refer to the CPS system documentation.
Terminal box
This is made up of IP 55 components and is fitted with a cable gland in
accordance with the tables below.
If required, the terminal box may be fitted in a different position (on the left or
right as seen from the drive end).
Terminal box positions
Cable gland
The position of the cable gland is on the right, seen from the drive end, unless otherwise specified at the time
of ordering.
Check that the cable radius of curvature is large enough to prevent water entering through the cable gland.
The cable glands are plastic as standard. On request, they can be brass, or marine type.
Cable gland positions:
Adapt the cable gland and its reducer if present to the diameter of the cable being used.
In order to maintain the terminal box's original IP55 protection, it is essential to tighten the cable gland seal
correctly (so that it cannot be unscrewed by hand).
If some cable glands are not being used, ensure that they are always covered and tighten them so that they also cannot
be unscrewed by hand.
2.5 - Optional brake
As an option, motors in the CPLS range can be fitted with a
failsafe brake from the FCPL range.
These brakes are fitted with:
- accessories: SO7 power supply device or CDF7/CDF10
doping device
- options: brake disk wear sensors, brake release sensors,
space heaters, temperature sensor(s) for brake coil
Electrical connection of the brake and its accessories can be
made either in a special brake terminal box (standard), or in the
motor main terminal box (on request).
For more information about the brake electrical wiring and
maintenance, see the manual specific to the brake installed on
your motor.
