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 mod-
ules 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 com-
pression plates, allowing either bare wire connections or crimped terminal lugs. Use
#6 size ring lugs for secure, reliable connections under severe shock or vibration.
For information about installing or removing a power module, refer to

Electrocution hazard – risk of serious personal injury or death
The device may have two power modules equipped, which may be connected to
separate power sources. Make sure all power sources are off before servicing the
power module terminals.

DANGER
In a high AC/DC and low DC (24/48 V) power module arrangement, the place-
ment of the AC and DC power supplies is not slot-dependent. Either power mod-
ule slot can be used for AC or DC power.
For maximum redundancy in a dual power module configuration, use two inde-
pendent power sources.
Use minimum #16 gage copper wiring when connecting terminal blocks.
