2.5 Connecting Power
The RUGGEDCOM RX1500 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.
For information about installing or removing a power module, refer to "Installing/Re-
moving Power Modules (Page 41)".
DANGER
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.
IMPORTANT
• 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.
• 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.
