9.1.5 General inspection
Check that
the installation conditions are observed. We recommend that the following checks
are performed after approx. 16 000 operating hours or at the latest after two years:
Table 9-2 Checks that have to be performed during the general inspection
Checking When the
motor is
running
At stand‐
still
The electrical parameters are maintained X
The permissible bearing temperatures are not exceeded X
The smooth running characteristics and machine running noise have not
deteriorated
X
The motor foundation has no cracks and indentations (*) X X
The machine is aligned within the permissible tolerance ranges X
All the fixing bolts/screws for the mechanical and electrical connections have
been securely tightened
X
All the potential connections, grounding connections and shield supports are
correctly seated and properly bonded
X
The winding insulation resistances are sufficiently high X
Any bearing insulation is fitted as shown on the plates and labels X
The CABLES and insulating parts and components are in good condition
and there is no evidence of discoloring
X
(*) You can perform these checks while the motor is at standstill or, if required, while running.
NOTICE
If you detect any deviations during the inspection, you must rectify them immediately. They
may otherwise cause damage to the machine.
9.1.6 Servicing the roller bearings
When inspecting rolling-contact bearings, it is generally not necessary to dismantle the
machines. The motor only has to be dismantled if the bearings are to be replaced.
All machines marked in accordance with Directive 94/9/EC (“Explosion Protection Directive”,
until April
19, 2016, according to Directive 2014/34/EU from April 20, 2016) must be regularly
