1.7 Operation
Operating without excitation (similar to a series-wound motor idling), can lead to dangerous over-
speed conditions and you must lock the machine to prevent this happening. Vibration levels of
v
eff
≤ 3.5 mm/s (P
n
≤ 15 KW) or 4.5 mm/s (P
N
> 15 KW) in coupled operation are insignificant.
If changes different from normal operation occur, e.g. increased temperatures, noises or vibrations,
switch off the motor if you are in doubt. Find out the cause and contact the manufacturer if necessary.
Never disable guards, even in test operation. When carrying out any inspection and maintenance
work, observe Section 1.5 and the details in the commissioning guide and maintenance instruc-
tions.
After approximately 100 operating hours, carry out first-time inspection of the brushes (for wear), the
commutator (for unusual discolouration), and the brush holders (for easy motion). After this, inspect
these components again approximately every 600 operating hours depending on the degree of wear
(refer to Section 4.1).
If the motor is fitted with ventilation with filter, you must carefully clean the filter every 100 operating
hours, depending on the degree of contamination.
If a lot of dirt accumulates, clean the airways regularly. From time to time, open any condensate
drain holes there may be on the equipment.
In the case of motors without regreasing devices, change the lubricant as advised by the manufac-
turer or after three years at the latest.
Regrease bearing assemblies that have regreasing devices while the motor is running.
If grease exit holes are sealed with plugs, remove the plugs before commissioning and seal the
holes with grease.
Important: Observe the information on the rating plate for regreasing intervals!
Under unfavourable operating conditions, it may be necessary to considerably
reduce the maintenance intervals!
Important!
You should always keep liquids and aggressive media, silicone and silicone com-
pounds and their vapours away from the motors. The only exceptions to this rule are
motors whose manufacturers have expressly designed them for specific applications
(e.g. use out of doors) and which have appropriate protection. The manufacturer
accepts no responsibility for damage resulting from ignoring this.
1.8 Electromagnetic Compatibility
Operation of the DC motor for its intended purpose must be in accordance with the requirements of
EMC Guideline 89/336/EWG. The plant installer is responsible for correct installation, e.g. physical
separation of the signal lines and the power cables, screened lines and cables, etc.
In the case of systems with converters, observe the manufacturer's EMC information.
1.9 Warranty
The warranty is dependent on this safety and commissioning information, as well as the data on any
additional equipment, being observed. For more details, refer to the detailed commissioning guide
and maintenance instructions below.
