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 i110H or with machines
protected by the i110H.
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
Only qualified safety personnel are authorised to mount, install and commission the
safety switch i110H. 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 switch
Safety switches of the i110H series are electromechanical safety interlocks.
They are fitted at the hinge point of swivelling guard doors and secure movable safety
guards so that
•the dangerous state of the machine can only be enabled when the safety guard is
closed,
•a STOP signal is generated when the safety guard opens while the machine is
operating.
For the control system this means that
•activation commands leading to dangerous states are allowed to become effective
only when the safety guard is in the protective position and dangerous states must
no longer exist when the safety guard opens.
Before installation of safety switches a risk assessment should be performed.
2.3 Correct use
The i110H 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.
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 protective notes and protective measures
Safety switches serve the purpose of protecting individuals. Tampering or incorrect
installation may result in severe personal injury.
WARNING
Do not override safety switches (by bridging contacts), turn them from their protective
position, remove them or defeat them in any other way.

3 Mounting
WARNING
Mounting is only allowed to be performed by qualified safety personnel.
bPay attention to EN ISO 14119 on mounting the safety switch.
Mount the safety switch such that
•It is difficult for operators to access.
•it can be inspected and replaced.
NOTICE
The safety switch and cams must be adequately secured against movement and cor‐
rectly keyed to each other.
To satisfy this requirement
•the mounting method must be secure and require a tool for removal,
1. Remove cover,
2. Mount safety switch with 2 screws M4 and tighten to 5.0 Nm,

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.

5 Commissioning
5.1 Tests before the first commissioning
•Mechanical function test
bOpen and close safety guard to check that it is moving smoothly.
•Electrical function test
bClose safety guard.
bTurn on machine.
WARNING
Check whether opening the safety guard stops the machine.
bTurn off machine.
bOpen safety guard.
WARNING
Machine must not start while safety guard is open!
5.2 Periodic technical inspections
To ensure correct function over the long term, regular checks are necessary.
Daily or prior to the start of the shift the operator must check for:
•correct function
•no visible evidence of tampering
Regularly according to the machine maintenance schedule by qualified safety person‐
nel:
•correct switching function
•safe mounting of the modules
•deposits and wear and tear
•correct sealing of the cable entry or plug connection
•loose cable connections or plug connectors
