DC (10–30V) Output Module Initial Handling Procedures ATTENTION ! Keying the I/O Chassis ATTENTION ! Place your module in any slot in the chassis except the leftmost slot, which is reserved for processors or adapters. ATTENTION ! Remove power from the 1771 I/O chassis backplane and field wiring arm before removing or installing an I/O module. • Failure to remove power from the backplane or wiring arm could cause module damage, degradation of performance, or injury.
