The RUGGEDCOM RX1501 supports a single high AC, high DC or low DC power mod-
ule.
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 42)".
DANGER
Electrocution hazard – risk of serious personal injury or death
Make sure all power sources are off before servicing the power module terminals.
IMPORTANT
• 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.
• For 125/230 VAC rated equipment, an appropriately rated AC circuit breaker
must be installed.
• For 125/250 VDC rated equipment, an appropriately rated DC circuit breaker
must be installed.
• It is recommended to provide a separate 20 A circuit breaker for each power
module module.
• Equipment must be installed according to applicable local wiring codes and
standards.
