Maintenance and Adjustment

• This unit contains no user-serviceable parts and should not be disassembled for any reason.
• Calibration is not required.

Removal and Insertion

• Field power supplied to this device, either at the field terminal or as bussed field power through the carrier, must be removed before removing or connecting the device.
• An I/O loop assessment must be complete on all energy-limited nodes.
• This unit cannot be removed or inserted with system power energized.
• Non-sparking field circuits MUST be de-energized before removing and inserting, including the fused terminal block.
• A rotary keying system ensures compatibility between I/O cards and terminal blocks after installation is complete. The terminal block must have the keys set for the I/O card with which it is to be used.
