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.

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.

Assembly

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 50 mm to maximum Ø 58 mm.

TIP

The product description will indicate whether an A- or V­assembly is involved.

► Position the SENSORswitch (B) in the A- or V-assembly, align

centered and vertically and mark 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!

4

Do not use grease or oils to apply the cover ring (A).
