6 Commissioning/Start-up/Shutdown
DANGER
Hazardous voltage
Danger of death from electric shock!
▷ Have all work performed only by qualified specialist personnel and only when
the drive is at a standstill and secured against unintentional start-up. This also
applies to auxiliary circuits (e.g. standstill heater).
▷ The drive must not be electrically connected at any point in time when work is
performed on the open terminal box.
Before commissioning and whenever returning the product to service, perform the
electrical safety checks stipulated by EN 60204-1.
6.1 Checking earth conductor connection
Check that the earth conductor has been correctly connected in accordance with
EN60204.
6.2 Checking insulation resistance
Prior to commissioning and following prolonged storage or standstill periods, the
insulation resistance will need to be checked and verified.
NOTE
If windings have been dried after having been repaired or cleaned, bear in mind
that the insulation resistance of warm windings is lower. The insulation resistance
can only be correctly evaluated after converting to the reference temperature of
25°C.
The insulation resistance of the stator winding must equal at least 1.5megohms in
motors for 220-1000V.
6.3 Prerequisites for commissioning/start-up
Before commissioning/starting up the drive, make sure that the following conditions
are met:
▪ The drive has been properly installed and aligned.
▪ The drive has been connected correctly for the specified direction of rotation.
▪ The operating conditions correspond to the data provided on the name plate.
▪ The output elements have been correctly configured depending on type (e.g.
alignment and balancing of couplings, belt forces for belt drive, tooth forces and
tooth flank clearance for gearwheel drive, radial and axial clearance for coupled
shafts).
▪ The earthing and equipotential bonding connections have been properly made.
▪ All fastening bolts, connecting elements, and electrical connections have been
properly tightened to the specified tightening torques.
▪ Screwed-in lifting lugs have been removed following installation or secured
against working loose.
▪ The shaft rotates freely.
▪ Measures have been taken to prevent accidental contact with moving and live
parts.
▪ The unused shaft end has been covered and the key secured to prevent it from
being thrown off.
▪ Components (cables, etc.) that are sensitive to temperature do not come into
contact with the motor housing.
