Check the state of the brake motor; if there is any damage to
the motor or even its packaging, inform the carrier.
Check that the brake motor conforms to the order (mounting
arrangement, information on the nameplates).

The motor can withstand a weak mechanical shock (IK 08
according to EN 50102).
The user must provide additional
protection if there is a high risk of mechanical shock.

1.2 - Storage
Store the equipment in a clean, dry location, protected
from shocks, vibrations, variations in temperature and in an
environment with relative humidity of less than 90%.
Storage for longer than 6 months leads to special conditions,
we will be happy to discuss these with you.
After storage for a period of more than 6 months, disconnect
the brake power supply unit and check the winding insulation
resistance (phase/earth resistance higher than 10 MΩ). Drain
any condensation water.
2 - RECOMMENDATIONS
2.1 - Commissioning
The brake motor is designed to operate at the speeds indicated
on the nameplate (do not exceed the maximum speeds stated
in our technical catalogues).
Comply with the voltages and frequencies indicated on the
nameplate (do not deviate by more than 5% from the voltage
extremes on the nameplate and by more than 1% from the
frequencies).
F
or hoisting applications, do not use a motor that is not rated
S3 (except for variable speed). Do not use a motor with a
different duty type from that on the nameplate no.

2.2 - Mechanical installation
(Also see manual 1889)
If the brake motor has been stored at a temperature lower
than -10°C, heat it and turn the shaft manually before starting
up the machine.
If the brake motor is to be used at a temperature lower than
-25°C, it must not be fitted with a sensor. It can be fitted with
thermocouples.
Ensure there is minimum clearance (corresponding to
the length of the cover) at the non-drive end of the brake
motor so it can be put down (inspections and brake
adjustments).
Install the brake motor in conditions conforming to those on
the order (temperature, relative humidity, altitude).
When the brake motor is fitted with lifting rings, these are
for lifting the brake motor on its own (tighten the ring, if
necessary, before handling).
Mount the brake motor in the position specified on the order,
on a flat, rigid base in order to prevent distortion and vibration.
Make sure that the holding screws are tightened to the correct
torque according to NF E25-030-1. (class 8.8 minimum
according to ISO 898-1), the screw diameter must be the right
size for the fixing holes.
Ensure the mechanical shafts are aligned and the
transmission mechanism is mounted in accordance with good
practice.
Ensure the mass continuity; no modifications to the brake
motor are authorised.
