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).
Do not use a motor with a different duty type from that on the
➈
nameplate n° .

2.2 - Mechanical installation

(Also see manual 1889)
If the brake motor has been stored at a temperature lower
than -10°C, warm it, unlock the brake 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). Protect
it from oily projections (according to the environmental
conditions according to EN 60721-3-4 4K2/4Z1/4Z5/4Z7/4B
1/4C2/4S2/4M3).
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 fixing 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.
Do not knock the motor (terminal box, cover), the shaft or
the coupling during mounting, do not crush the seal, do not
project beyond the shoulder of the shaft.
Ensure correct brake motor cooling, the air intakes and outlets
must be kept clear.
Check that the loads applied to the motor shaft (especially
the belt tension) are compatible with the values stated in our
technical catalogues.
