SAFETY INSTRUCTIONS 7
2 SAFETY INSTRUCTIONS
2.1 Safety
This section gives an overview of all important safety aspects relating to the protection of personnel as well as
the safe use and fault-free operation. Other, task-specific safety instructions can be found in the sections on
the individual phases of the product's life.
DANGER!
Failure to observe the safety instructions may result in risks to life and health!
2.2 Intended use / foreseeable misuse
VCL compact conductor systems (type VCL2+VCL3) are contact-protected 2- to 3-pin conductor rails. The con-
ductor systems can be combined with any number of pins and allow direct routing in track supports and sup-
port profiles. The conductor rail is only to be used for indoor installations. It can be mounted hanging or
laterally.
Appropriate use includes following all the information in these instructions.
Any use beyond or other than the appropriate use, conversion or other modification is to be considered misuse
and prohibited.
WARNING!
Danger in case of misuse!
Misuse may cause dangerous situations.
►Never use the system for anything but the intended use.
►Never let non-instructed personnel operate the system.
►Never modify or change the system improperly.
►Never operate the system in ways that disregard the safety instructions.
►Never use the system for outdoors applications.
►Never operate the system at higher currents or voltages.
►Never operate the system with contacts made by other manufacturers.
►Never expose the system to large amounts of water.
Claims for damages resulting from improper use shall be invalid.

SAFETY INSTRUCTIONS 8
2.3 General risks
The following section describes residual risks that arise even if the product is used as intended. Observe the
safety instructions listed here in the other sections of these instructions to reduce the risk of injuries or dam-
age to property and equipment and to avoid dangerous situations.
Do not change or modify the system inappropriately!
WARNING!
Risk of death from improper replacement or removal!
Errors during the removal or replacement of components may cause life-threatening
situations or significant property damage
►Observe the safety instructions before beginning any removal work.
2.3.1 Danger from electrical energy
Perform the following safety work according to VDE 0105-100 (this work must be carried out by a qualified elec-
trician, see chapter: "2 security").
Activate
The required separation distances must be established.
Secure against restart
During work, a prohibition sign must be attached reliably on switching handles or drives of switches, control
units, pressure and sensing devices, safety parts, circuity breakers that have been used to unlock a system
part or that can be used to connect electricity. If this is not possible, then the clearly associated prohibition
sign must be nearby. Existing mechanical interlocking devices against restart must be used for manually op-
erated switches.
Determine absence of voltage
Absence of voltage is to be determined at or as close as possible to the work site at all poles. Absence of volt-
age must be checked with a voltage tester immediately before and after use.
Grounding and short-circuiting
Parts on which work will be performed at the work place must first be grounded and then short circuited.
Grounding and short-circuiting must be visible from the workplace. Deviating from the above, it is permitted to
ground and short-circuit near the work place if this is required due to local conditions or for safety reasons.
Devices for grounding and short-circuiting must always first be connected with the grounding system or the
ground electrode and afterwards with the parts to be grounded. Grounding and short circuiting may be waived
in certain low-voltage systems (see VDE 0100-100).
