2 On safety
This chapter deals with your own safety and the safety of the equipment operators.
bPlease read this chapter carefully before working with the i17S or with the
machine protected by the i17S.
The national/international rules and regulations apply to the installation, commission‐
ing, use and periodic technical inspections of the safety switches, in particular
•the Machinery Directive,
•the Low Voltage Directive,
•the Work Equipment Directive,
•the safety regulations as well as
•the work safety regulations/safety rules.
Manufacturers and operators of the machine on which the protective devices are used
are responsible for obtaining and observing all applicable safety regulations and rules.
2.1 Qualified safety personnel
The i17S safety switch must be mounted, installed and commissioned only by qualified
safety personnel. Qualified safety personnel are defined as persons who
•have undergone the appropriate technical training
and
•have been instructed by the responsible machine owner in the operation of the
machine and the current valid safety guidelines
and
•who have access to these operating instructions.
2.2 Applications of the safety switches
Safety switches of the i17S series are electromagnetic switching devices.
They secure moving protective devices with a guard function so that
•the dangerous state of the machine can only be switched on when the guard is
closed,
•a STOP command is triggered if the protective device is opened while the machine
is operating.
For the control this means that
•activation commands that cause dangerous conditions, may only become active
when the guard is in the protective position and the dangerous conditions have
been terminated before the protective position is cancelled.
Prior to the use of safety switches, a risk assessment must be performed on the
machine.
WARNING
If the safety switches are connected in series the Performance Level (PL) may be
reduced due to reduced fault detection, depending on the application (ISO/TR 24119).

2.3 Correct use
The i17S safety switch must be used only as defined in section 2.2 “Applications of
the safety switches”.The safety switch must be used only on the machine where it has
been mounted, installed and initialized by qualified safety personnel in accordance with
these operating instructions.
The product may be used in safety functions.
All warranty claims against SICK AG are forfeited in the case of any other use, or
alterations being made to the safety switch, even as part of its mounting or installation.
Correct use includes the regular inspection of the protective device by qualified safety
personnel in accordance with section 5.2.
2.4 General safety notes and protective measures
Safety switches provide a protection function for persons. Incorrect installation or
manipulation can result in serious injuries.
WARNING
Safety switches are not allowed to be bypassed, turned away, removed or made ineffec‐
tive in any other manner. Take measures to reduce bypassing options as necessary.
Observe EN ISO 14119 for using interlocking devices associated with physical guards.
WARNING
The switching procedure may only be activated by actuators specifically designated for
that purpose, which are connected to the protective device in such a manner that they
cannot be detached.
Restrict access to replacement actuators, so they cannot be used for bypassing.

3 Mounting
WARNING
Mounting is only allowed to be performed by qualified safety personnel.
bObserve EN ISO 14119 for using interlocking devices associated with physical
guards.
Fit the safety switches such that
•it is difficult for operators to access when the protective device is open,
•it is possible to inspect and replace the safety switches.
NOTICE
Safety switches and actuators must not be used as a mechanical stop.

bTo fix the safety switch, fit additional dowel pins.
bConnect the actuator to the protective device durably and non-detatchably, e.g.
using one-way bolts or by riveting or welding.
bFit an additional stop for moving parts of the guard (see figure 2).
bInsert the actuator into the actuating head.

3.2 Protection against surroundings
A precondition for a durable and perfect safety function is the protection of the
actuating head against penetration by foreign matter such as shavings, sand, abrasive
materials etc.
Cover the control slot, the actuator and the type label when painting.
