Connecting Power

The RUGGEDCOM RX1510 supports dual redundant high AC, high DC and/or low
DC power modules that can be installed in any combination. The use of two power
modules is recommended to provide redundancy and load balancing.
Power modules can be equipped with either a screw or European-style (Euroblock)
terminal block. The screw terminal block is installed using Phillips screws and
compression plates, allowing either bare wire connections or crimped terminal lugs.
For information about installing or removing a power module, refer to

NOTICE
In a high AC/DC and low DC (24/48 V) power module arrangement, the
placement of the AC and DC power supplies is not slot-dependent. Either power
module slot can be used for AC or DC power.
For maximum redundancy in a dual power module configuration, use two
independent power sources.
Use minimum #16 gage copper wiring when connecting terminal blocks.
The maximum wire length between the terminal block and power source must
not exceed 6 m (20 ft) for 24 V power supplies or 18 m (60 ft) for 48 V power
supplies.
