Wiring
5.1
Connecting the Power Supply and LAN
The ASCO 5010 Remote Display Unit requires 48V DC to operate. The unit can receive this power from one of two inputs:
1.
48V DC power input terminal
2.
The LAN jack using PoE (Power over Ethernet) from the ASCO 5400 Series Power Quality Meter labeled LAN2/LCD.
When both inputs are in use, the primary source of power is from the 48V DC input terminal, with the PoE offering backup
redundancy.
5.2
Connecting the 48V DC Terminal
For safely connecting 48V DC follow these instructions:
Ensure the panel under work is de-energized.
Prepare the 48V DC terminal block connector provided with the ASCO 5010 Package
Attach lugged ends of wires to the terminal block using a properly sized screw driver
√
The positive wire is to be attached to the terminal
√
The negative wire is to be attached to the terminal marked -
Insert the 48VDC terminal block into the socket marked "48V DC" as shown above in
Figure 3
.
The ASCO 5010 Remote Display Unit will operate efficiently using a voltage range from 24-51V DC, however only 48V DC
may be used through the PoE input (LAN2/LCD socket on the ASCO 5450 and 5490 Power Quality Meters).
5.3
Power over Ethernet (PoE)
POE is a standard for feeding DC power to an RTU (Remote Terminal Unit) using the network RJ45 cable without the
need for additional external power.
The ASCO 5010 contains a single LAN port with support for receiving PoE (In) but not for providing PoE (Out) to other
devices.
To take advantage of the PoE option, connect the RJ45 jack to the port marked "LAN2/LCD" on the ASCO 5400 Series Power
Quality Meter as shown in Figure 7.
