Safety information
2.7 Processes that generate high levels of electrostatic charge
WARNING
Risk of explosion due to electrostatic discharge
Electrostatic discharge poses a potential ignition source. Dangerous electrostatic charges
can occur, for example as a result of mechanical friction, flowing air that contains particles or persons that are not appropriately grounded, e.g. when carrying out maintenance or
cleaning work.
In an explosive atmosphere, there is a risk of an explosion. This can result in death, serious
injury or material damage.
● Avoid carrying out work specified above on non-metallic parts, e.g. foam rubber for noise
dampeners/attenuators.
● Please comply with ESD protective measures.
2.7 Processes that generate high levels of electrostatic charge
Processes that generate high levels of electrostatic charge, which are far higher than those
generated through manual rubbing, include the following:
● Operation of high-voltage electrodes and ionizers
● Presence of high-speed particles on surfaces, e.g. sprayed charges (electron and ion flows)
in electrostatic coating processes
● Pneumatically conveyed dusts and bulk goods
● Flowing or hydraulically conveyed liquids and drops
● Belts, brushes and foils etc. moved by machines
WARNING
Risk of explosion as a result of processes with high levels of electrostatic charging
Processes with high levels of electrostatic charging can result in propagating brush discharge/
brushing discharge and explosion
This can result in death, serious injury or material damage.
● Avoid all of these processes in areas where there is risk of gas and dust explosions at
non-metallic exposed components, e.g. paint finishes. These discharge types are not
addressed in current standards.
● The non-metallic exposed components, e.g. paint finishes are subject to an electrostatic
suitability test in the factory. When supplied, the motor has its original paint finish.
Use the tested, original paint when repainting or touching up. It is possible to use a paint
that has not been tested by Siemens, which is however suitable from an electrostatic
perspective. The operating company is responsible for carrying out an electrostatic test
of the complete system.

Safety information
2.8 Interference immunity
2.8 Interference immunity
By selecting suitable signal cables and evaluation units, companies operating complete plants
and systems must ensure that the interference immunity of the machine is not diminished.
2.9 Influence on the line power supply through a strongly irregular torque
A strongly irregular torque, for example with the drive of a reciprocating motor, forces a nonsinusoidal motor current. The emerging harmonics can have an impermissible influence on
the line power supply via the connection lines.
2.10 Interference voltages when operating the converter
WARNING
Interference voltages when operating the converter
When a converter is in operation, the emitted interference varies in strength depending on
the converter (manufacturer, type, interference suppression measures undertaken). On
machines with integrated sensors (e.g. PTC thermistors), interference voltages caused by
the converter may occur on the sensor lead. This can cause faults which can result in eventual
or immediate death, serious injury or material damage.
● Comply with the EMC information provided by the manufacturer of the converter. This is
how you prevent the limit values stipulated by IEC/EN 61000-6-3 for the drive system
(consisting of the machine and converter) from being exceeded.
● You must put appropriate EMC measures in place.
2.11 Electromagnetic fields when operating electrical power engineering installations
WARNING
Interference to electronic devices caused by electrical power equipment
Electrical power equipment generate electric fields during operation. Potentially lethal
malfunctions can occur in medical implants, e.g. pacemakers, in the vicinity of electrical power
equipment. Data may be lost on magnetic or electronic data carriers.
● It is forbidden for people with pacemakers to enter the vicinity of the machine.
● Protect the personnel working in the plant by taking appropriate measures, such as
erecting identifying markings, safety barriers and warning signs and giving safety talks.

Automatic regreasing system (option)
The roller bearings are optionally equipped with an automatic regreasing system. The roller
bearings are supplied with new grease portions by the regreasing system in parameterized
time intervals.
Rolling-contact bearing design for "Increased degree of protection" (option)
Improved sealing of the bearing units to prevent dust and water from getting in can be achieved
by positioning a grease chamber ahead of the actual bearing unit. Although the same grease
is used in both cases for reasons of convenience, a distinction is made here between
"lubricating grease" and "sealing grease" because of their different functions.
Layout
The spent lubricating grease collects in the space between the bearing housing and the outer
bearing cap. The latter also forms the sealing grease chamber with the labyrinth sealing ring
(optional). The second lubricating nipple containing the grease duct for pressing in the sealing
grease is also located in the outer bearing cap. The chamber is sealed off from the space
where the lubricating grease collects by a V-ring or a V-ring and felt ring combination which
prevents the sealing grease in the chamber from penetrating into the lubricating grease
collecting space. During operation, the sealing grease in the chamber slowly runs out via the
labyrinth and seals it, additionally removing dust from inside and around the outside of the
labyrinth ring.
