Safety
General safety
All work on electrical systems or operating equipment may only
be carried out by a specially qualified electrician according to the
applicable electrotechnical regulations.
The safety of the system in which the SENSORswitch is integrated
is the responsibility of the operator.
Notes and symbols used
Warning notes in relation to personal injury / material damage are
formulated according to the "SAFE” principle. This means they
contain information on the type and source of the hazard, potential
consequences as well as how to avoid and avert danger. The
following hazard classifications apply in the safety notes:
DANGER
Danger designates a hazardous situation, which,
if ignored, will lead to death or serious injury. The
symbol next to the warning indicates the type
and source of the danger.

WARNING
Warning designates a hazardous situation,
which, if ignored, may lead to death or serious
injury. The symbol next to the warning indicates
the type and source of the danger.
CAUTION
Caution designates a hazardous situation, which,
if ignored, may lead to injury. The symbol next to
the warning indicates the type and source of the
danger.
NOTICE
Notice designates a situation, which may cause material
damages and impair the product’s function if attention is not
paid.
TIP
Tip provides additional useful information about the handling of
the product.
Symbol Meaning

WARNING
Improper work on electrical systems!
Electric shock can result in death or life-
threatening injuries.
4Before working on electrical systems,
disconnect them from their voltage supply
and secure them against being switched on
again.
4Work on electrical installations should be
carried out only by qualified personnel in
compliance with local and national electrical
regulations and specifications.
Personnel qualifications
A qualified electrician is a person with suitable technical training,
expertise and experience as well as knowledge of relevant
standards, who can evaluate the work assigned to them
correspondingly and recognize potential risks.
Intended use
The SENSORswitch is intended for use in accordance with the
items listed here, the values from the “Technical specifications”
chapter and the product description.
■Only connect the product to a limited energy source as per IEC
61010 or an NEC class 2 power supply unit.
■Source current < 4 A at maximum operating voltage.
Reasonably foreseeable misuse
Any use other than as specified in the section Intended use or
extending beyond this is deemed to be improper.
The SENSORswitch is not suitable for:
■use in potentially explosive atmospheres.
■use as a safety component as per directive 2006/42/EC.

General description
The supplied SENSORswitch can have options that differ from
those shown in this manual. This does not affect the function. The
SENSORswitch is equipped with different color LEDs to indicate
operating conditions. The LEDs are actuated differently depending
on the pin configuration.

WARNING
Improper work on electrical systems!
Electric shock can result in death or life-
threatening injuries.
4Before working on electrical systems,
disconnect them from their voltage supply
and secure them against being switched on
again.
4Work on electrical installations should be
carried out only by qualified personnel in
compliance with local and national electrical
regulations and specifications.
Requirements: Mounting surface is level and clean.
► Disconnect the system from its voltage supply and secure it
against being switched on again.
► Set the desired position of the SENSORswitch and provide a
center hole of minimum Ø 58 mm to maximum Ø 60 mm.

TIP
Without an acoustic signal transmitter, a hole with a
diameter of 27 mm is sufficient.
► Position the SENSORswitch (B), lining up the center and
vertical axis, and mark the holes (C).
► Select the diameter of the holes according to the recommended
screw type and start drilling.
► Connect the SENSORswitch (B) electrically according to the
connection plan.
► Install the SENSORswitch (B) with the recommended screws.
The screw head must not deform the mounting flange (B).
► Place cover ring (A) with
groove (D) downward and
press close to the button
surface. The cover ring
must be flush with the entire
button surface.
NOTICE
Mineral grease and oils can attack the plastic of the button!
4Do not use grease or oils to apply the cover ring (A).

Recommended screw types
■DIN EN ISO 1207 M4
■DIN EN ISO 7045 M4
■DIN EN ISO 1481 Ø3.9 mm
■DIN EN ISO 7049 Ø3.9 mm
Maximum dimensions of the screws
The drawing shows the
maximum dimensions of the
screws.
Maintenance
Maintenance operations
Carry out the following maintenance operations at the specified
intervals.

Maintenance operation as needed annually
Clean the button surface X
Check cables for intactness and firm
fit
X
Check screw connections for
tightness
X
NOTICE
Solvents contained in cleaning agents can attack the
plastic of the button!
4Clean the surface of the button with a neutral cleaning agent
or a damp microfiber cloth.
Disassembly
► Disconnect the system from its voltage supply and secure it
against being switched on again.
► Insert the flat head screwdriver into the groove (D) on the cover
ring (A) and remove the cover ring with the screwdriver via lever
action.
► Loosen the screw connections and disconnect the electrical
connection.
Disposal
Different types of electrical and electronic components must be
recycled according to their type. All applicable statutory, state and
local laws and regulations must be complied with.
