Overview
The EKI-1500-CE Series supports dual 12 to 48 VDC power inputs and power-fail
relay output.
The following figure illustrates a P-Fail alarm application example. The P-Fail alarm
contacts are visible on the front view of the terminal block.
Figure 2.19 Power Wiring for EKI-1500-CE Series
You can connect an alarm indicator, buzzer or other signaling equipment through the
relay output. The relay opens if power input 1 or 2 fails. In a wiring example where an
LED is connected to the relay output, the LED would be off in an Open state.
Warning!
Power down and disconnect the power cord before servicing or wiring
the serial device server.
Caution!
Do not disconnect modules or cabling unless the power is first switched
off.
The device only supports the voltage outlined in the type plate. Do not
use any other power components except those specifically designated
for the serial device server.
Caution!
Disconnect the power cord before installation or cable wiring.
