3.3 General safety instructions
Safety instructions:
•To prevent injury and damage, only qualified personnel are allowed to work on the
device. Qualified personnel are personnel who have electrical engineering training and
who are familiar with the applicable rules and standards of electrical engineering.
•The qualified person must familiarise himself with the operating instructions
(cf. IEC 364, DIN VDE0100).
•The qualified person must have, as a minimum, detailed knowledge of national health
and safety regulations
•The usage of the devices is to be limited to their intended usage as per the list given
above. The values in the data listed in section "3.2. Device characteristic data" are also
to be met.
•The content of these installation instructions is limited to the basic function of the
devices and their installation. The programming of the devices and re-configuration of
the device parameters is further described in the "Programming instructions
SafePLC2". Detailed knowledge and understanding of this information is a vital
prerequisite for a new installation or the modification of the device function or device
parameters.
•Commissioning (i.e. commencing operated as intended) is only allowed on compliance
with the EMC directive. The EMC test standards EN55011:2007 + A2:2007 and EN
61000-6-2:2005 are used as the basis.
•For storage and transport, the conditions according to IEC 60068-2-6 in relation to the
values stated in "Tech. characteristic data" must be met
•It is imperative the wiring and connection instructions in the section "Installation" are
followed.
•The applicable VDE regulations as well as other special safety regulations for the
specific application must be followed.
•The monitoring functions configured as well as their parameters and operators must be
validated via a validation report.
•The module's implementation is to be agreed with the responsible body (e.g. TÜV or
BG).
•Never install or place in operation damaged products. Please report any damage
immediately to the transport company.
•Never open the housing and/or make unauthorised modifications.
•Inputs and outputs for standard functions and the digital and analogue data transmitted
via communication interface are not allowed to be used for safety-related applications.

WARNING:
The usage of our devices contrary to the rules and conditions stated here can result in the
injury or the death of persons, as well as damage to the devices and machines connected!
This usage will also render void any claim under the warranty or any claim for claim damages
against the manufacturer.
3.4 Operating and service
Prior to installing and removing the module, or disconnecting the signal wires, the module is to
be electrically isolated. For this purpose all electrically live supply wires to the device are to be
switched off and it is to be checked that there is no electrical power present on the wires.
During the installation and removal of the module, appropriate
measures are to be taken to prevent electrostatic discharges on the external terminals and
connections. Contact with these terminals should therefore remain limited to a minimum; prior
to and during this work you should be earthed, e.g. using an earthing wrist strap.

Basic devices
The series PSC1-C-100 series is a modular safety controller. The device is freely programmable
for the safe processing of EMERGENCY STOP buttons, two-hand controls, light barriers, operating
mode selector switches, etc. and also drive-related safety functions. For the safety-related signal
processing, pre-configured blocks are available for a large number of input devices. The same
applies for safety functions for drive monitoring. You will find details in the programming manual.
In the basic version the device has 14 safe inputs and up to 25/23 safe 2-channel shutdown
channels. (4x PP or 2x PN semiconductor outputs, 1x 2-channel relay output, 20x safe
switchable inputs/PP semiconductor outputs)
For safe speed and/or position acquisition, 1-encoder solutions and 2-encoder solutions are
supported. See "Encoder specifications".
Expansion modules
Central or decentral I/O or axis expansion modules for the PSC1-C-100 series.
A maximum of 8 expansion modules can be connected to a system, of these 6 axis expansion
modules are allowed to be used.
Integrated communication interface
The communication interface has bidirectional data transmission from and to a higher level
controller using a standard fieldbus or safe standard fieldbus.
