Field Installation Guidelines

• Verify the module model and electrical specifications against the equipment documentation before installation.
• Confirm the 24 VDC nominal supply and ensure the actual input voltage remains within the specified 18 to 32 VDC range.
• Check terminal assignments and polarity before connecting power.
• Route power wiring separately from sensitive analog signal and communication cables where practical.
• Apply the cabinet grounding and protective earthing practices specified by the system manufacturer.
• Confirm the module’s mounting method, ventilation requirements, and compatibility with the target control system before energizing it.
