This manual has been written for technicians/installers and
operators and should be kept for future reference. Read these
operating instructions carefully and make sure that you have fully
understood the contents before installing or working with the CHT3.
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.

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
The switch is not suitable for:
•use as a foot switch.
•use in potentially explosive atmospheres.
•use with inductive loads without a free-wheeling diode.
•use as a safety component as per directive 2006/42/EC.
