ATTENTION:
Wiring Guidelines
• Disconnect the module from the power supply before wiring or connecting
cables. Devices connected to the module can operate unexpectedly if wiring
is performed while power is supplied.
• Wire correctly after confirming the signal names of all terminals.
• Wire the Guard I/O™ modules properly so that 24V DC line does not touch
the safety outputs accidentally or unintentionally.
• Do not route communication, input, or output wiring with conduit
containing high voltage. Refer to Industrial Automation Wiring and
Grounding Guidelines, publication
• Wire conductors correctly and verify operation of the module before placing
the system into operation. Incorrect wiring can lead to loss of safety
function.
ATTENTION:
Be Aware of Safety Requirements
Personnel responsible for the application of safety-related programmable
electronic systems (PES) shall be aware of the safety requirements in the
application of the system and shall be trained in using the system.
ATTENTION:
Electrical Safety Considerations
To comply with the CE Low Voltage Directive (LVD), all connections to this
equipment must be powered from a source compliant with the following:
• Safety Extra Low Voltage (SELV) Supply.
• Protected Extra Low Voltage (PELV) Supply.
If the devices (sensors) connected to the input connections require Class 2
power to operate, the auxiliary power connections of this equipment must be
powered by a Class 2 source.
ATTENTION:
Maintain IP Rating for 1732ES Modules
Make sure all connectors and caps on 1732ES modules are securely tightened to
properly seal the connections against leaks and maintain IP enclosure type
requirements.
Applicable only to 1732ES modules.
