Schneider Electric XPSMF2DO801 manual Modules, Step Action

Application and Function

Replacing Faulty If a safety remote output device fails, the following replacement procedure is used:

Modules
	Step	Action
	1	Disconnect power supply to the specific module.
	2	Disconnect all terminals (removing input or output wires is not required).
	3	Disconnect communication - Ethernet from the remote output module.
	4	Loosen the DIN rail clip and dismount the module.
	5	Mount the new module and release the DIN rail clip.
	6	Re-connect power supply.
	7	Connect to the PC that is executing XPSMFWIN via Ethernet cable.
	8	Enter new communication settings for MAC address and IP address.
	9	Download the configuration used by the previous module.
	10	Connect all output terminals to the new module. Rewiring is not necessary, but
		the terminals must be inspected to ensure they are in good operating condition.
	11	Re-establish network connection.
	12	Run the module.

Testing the Inputs and Outputs for Interference Voltage and Earth Faults

Inadmissible interference voltage can be measured with a universal tester. We recommend testing every single terminal for unapproved interference voltage.

When testing the external cables for insulation resistance, short-circuit, and line break, the cables must not be connected at both ends to prevent defects or destruction of the XPSMF2DO801 caused by excessive voltages.

Earth faults are to be tested before connecting the field cable to the devices. The feed voltage must be disconnected from the sensors, as well as between the negative pole and the actuators. If the negative pole is earthed during operation, the earth connection must be disconnected while testing for earth faults. This also applies to the earth connection of an existing earth fault tester. Every terminal can only be tested against earth with a resistance tester or a similar test instrument.

Testing the insulation of one or more wires against earth is admissible, but not two muted wires. High voltage testing is also not admissible.

Guidelines to measure circuit voltage and insulation resistance can be found in EN 50178.
