Page 15: Connecting A Power Supply
To comply with the CE Low Voltage Directive (LVD), the GLT must be powered by a DC source compliant with Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV). The following Rockwell Automation Bulletin 1606 power supplies are SELV- and PELV-compliant. • 1606-XLP30E •... - Page 16 Regardless of how these are wired, performance remains the same. The GLT successfully recognizes when one or both channels open, and the GLT detects cross channel faults and single channel faults to +24V and to 24V common.
