ATTENTION:
Follow these precautions for safe use.
Wire conductors correctly and verify operation of the module
before placing the system into operation. Incorrect wiring may lead
to loss of safety function.
Do not apply DC voltages exceeding the rated voltages to the
module.
Apply properly specified voltages to the module inputs. Applying
inappropriate voltages may cause the module to fail to perform it’s
specified function, which could lead to loss of safety functions or
damage to the module.
Never use test outputs as safety outputs. Test outputs are not
safety outputs.
Note that after installation of the module, a safety administrator
must confirm the installation and conduct trial operation and
maintenance.
Do not disassemble, repair, or modify the module. This may result
in loss of safety functions.
Use only appropriate components or devices complying with
relevant safety standards corresponding to the required safety
category and safety integrity level.
•
Conformity to requirements of the safety category and safety
integrity level must be determined for the entire system.
•
We recommend you consult a certification body regarding
assessment of conformity to the required safety integrity level
or safety category.
Note that it is up to the user to confirm compliance with the
applicable standards for the entire system.
Disconnect the module from the power supply before wiring.
Devices connected to the module may operate unexpectedly if
wiring is performed while power is supplied.
