Page 8 EN Assembly instructions
2. Lubricants
2.1 General information
All products from SKF Lubrication
Systems Germany GmbH may be used
only for their intended purpose and in
accordance with the information in the
product's assembly instructions.
Intended use is the use of the products for the
purpose of providing centralized lubrication/
lubrication of bearings and friction points
using lubricants within the physical usage li-
mits which can be found in the documentation
for the devices, e.g., assembly instructions/
operating instructions and the product de-
scriptions, e.g., technical drawings and cata-
logs.
Hazardous materials of any kind, especially
the materials classified as hazardous by CLP
Regulation EC 1272/2008 may only be used
to fill SKF centralized lubrication systems and
components and deliv-ered and/or distributed
with the same after consulting with and recei-
ving written approval from SKF.
No products manufactured by SKF Lubrication
Systems Germany GmbH are approved for
use in conjunction with gases, liquefied gases,
pressurized gases in solution, vapors, or such
fluids whose vapor pressure exceeds normal
atmospheric pressure (1013 mbar) by more
than 0.5 bar at their maximum permissible
temperature.
Other media which are neither lubricant nor
hazardous substance may only be fed after
consultation with and written approval from
SKF Lubrication Systems Germany GmbH .
SKF Lubrication Systems Germany GmbH
considers lubricants to be a component of the
system design which must be factored into the
selection of components and the design of
centralized lubrication systems. The lubricating
properties of the lubricants are critically im-
portant in these considerations.
2.2 Selection of lubricants
Observe the instructions from the
machine manufacturer regarding the
lubricants that are to be used.
Warning!
The amount of lubricant required at
a lubrication point is speciied by the
bearing or machine manufacturer. It
must be ensured that the required
quantity of lubricant is provided to the
lubrication point. The lubrication point
may otherwise not receive adequate
lubrication, which can lead to damage
and failure of the bearing.
The selection of a lubricant suitable for
the lubrication task is made by the machine/
system manufacturer and/or the operator of
the machine/system in cooperation with the
lubricant supplier.
The bearings/friction points that require lubri-
cation, their expected load during operation,
and the expected ambient conditions are taken
into account during selection, with consider-
ation of economic and environmental aspects.
Page 9 ENAssembly instructions
2.4 Lubricants and the environment
Lubricants can contaminate soil and
bodies of water. Lubricants must be
properly used and disposed of. Observe
the local regulations and laws regarding
the disposal of lubricants.
It is important to note that lubricants are envi-
ronmentally hazardous, flammable substances
which require special precautionary measures
during transport, storage, and processing.
Consult the safety data sheet from the lubri-
cant manufacturer for information regarding
transport, storage, processing, and environ-
mental hazards of the lubricant that will be
used.
The safety data sheet for a lubricant can be
requested from the lubricant manufacturer.
SKF Lubrication Systems Germany
GmbH supports customers
in the selection of suitable components
for feeding the selected lubricant and in
the planning and design of a centralized
lubrication system.
Please contact SKF Lubrication Systems
Germany GmbH if you have further questions
regarding lubricants. Lubricants can be tested
in the company's laboratory for their suitability
for pumping in centralized lubrication systems
(e.g., "bleeding").
You can request an overview of the lubricant
tests offered by SKF Lubrication Systems
Germany GmbH from the company's Service
department.
2.3 Approved lubricants
Only lubricants approved for the prod-
uct may be used. Unsuitable lubricants
can lead to failure of the product and to
property damage.
Different lubricants cannot be mixed, as
mixing may result in damage and ne-
cessitate costly and complicated clean-
ing of the product/lubrication system.
It is recommended that an indication of
the lubricant in use be attached to the
lubricant reservoir in order to prevent
accidental mixing of lubricants.
The product described here can be operated
using lubricants that meet the specifications in
the technical data. Depending on the product
design, these lubricants may be oils, fluid
greases, or greases.
Oils and base oils may be mineral, synthetic,
and/or rapidly biodegradable. Consistency
agents and additives may be added depending
on the operating conditions.
Note that in rare cases, there may be lubri-
cants whose properties are within permissible
limit values but whose other characteristics
render them unsuitable for use in centralized
lubrication systems. For example, synthetic lu-
bricants may be incompatible with elastomers.

2.5 Lubricant hazards
Centralized lubrication systems must
always be free of leaks. Leaking lu-
bricant is hazardous due to the risk of
slipping and injury. Be mindful of any
lubricant leaking out during assembly,
operation, maintenance, and repair of
centralized lubrication systems. Leaks
must be sealed off without delay.
Lubricant leaking from centralized lubrication
systems is a serious hazard. Leaking lubricant
can create risks that may result in physical
harm to persons or damage to other material
assets.
Follow the safety instructions on the
lubricant's safety data sheet.
Lubricants are a hazardous substance. The
safety instructions on the lubricant's safety
data sheet must be strictly followed. The safety
data sheet for a lubricant can be requested
from the lubricant manufacturer.

5.1 General information
The LC502 control cubicle is designed as a
compact module for simple assembly and con-
tains the LC502 control unit as well as all
components essential for a control cubicle, such
as the basic power switch, motor circuit break-
er (230/400 VAC types), start button, and fault
indicator light.
The display itted to the front can be used to
enter customer-speciic system settings in a
simple and easy-to-follow way. The control
cabinet meets the requirements of the IP54
safety class if the cable glands are assembled/
closed as described in the assembly
instructions.
The LC502 control cubicle and its components
is designed for the control of either dual-line,
progressive, or single-line centralized lubrica-
tion systems, depending on the coniguration.
