2. General safety regulations and protective measures
• The manufacturer and users of the plant / machine on which the protection is being used are responsible
for implementing and following all applicable safety regulations and rules.
• When used in conjunction with the higher-order controller, the protection guarantees functional safety,
but not the safety of the entire plant / machine. The safety of the entire plant / machine must, therefore,
be assessed in accordance with machinery directive 2006/42/EC or appropriate product norm before
using the device.
• The operating instructions must always be available at the place of installation of the protection.
They must be read thoroughly and observed by all persons involved in the operation, maintenance and
servicing of the protection.
• The protection must only be installed and commissioned by professionals familiar with these operating
instructions and the applicable operational safety and accident prevention regulations. All of the instruc
-
tions provided in these operating instructions must be observed and followed.
All electrical work must only be performed by skilled electricians.
• All relevant electrical engineering and Employer's Liability Insurance Association safety regulations must
be observed.
•
During work on the switching unit, it is to be switched to zero potential, checked to ensure that it is at
zero potential and protected against being restarted.
• If the potential-free contacts of the relay outputs are supplied externally with a dangerous voltage, make
certain that these outputs are also switched off during work on the switching unit.
• The switching unit does not contain any components that require servicing by the user.
Unauthorised conversions and repairs made to the switching unit will void all guarantees and the
manufacturer’s liability.
• The protection system is to be professionally inspected at appropriate intervals and be documented in
such a way that it is comprehensible at all times.
Safety advice
• The switching unit enables operation at 230 V or at 24 V. Connecting the operating voltage to the wrong
terminals can destroy the switching unit.
• auxiliary terminal 31, 32 serves only as an auxiliary terminal (display, etc.) and must not be integrated in
the safety circuit.
• The switching unit is to be installed in a switching cabinet.
• Do not install in the immediate vicinity of strong sources of heat.
• For capacitive and inductive loads, ensure adequate protective circuits.
For the design of the safety system to conform to engineer standards acc. to EN
ISO 13849-1:2008 category 2, the safety system must be tested prior to each
dangerous movement of the plant / machine. Without testing, the operation or
wiring of the ELMON rail 34-32 safety relay does not satisfy these safety require
-
ments.
The manufacturer assumes no liability in the event of non-observance or intentional
abuse.
