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 may be removed or inserted while system power is energized under the following conditions: (Note Only one unit at a time may be removed with system power energized.) • When used with KJ1501X1-BC1 System Dual DC/DC Power Supply operating on 24 VDC or 12 VDC input power. The primary circuit wiring inductance for input power must be less than 23 uH, or a certified supply with an open circuit voltage, Ui of 12.6 VDC and an Lo of less than 23 uH (including wire inductance). 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. A terminal block fuse may NOT be removed with field power energized for non-sparking circuits.
