Connecting Power
The RUGGEDCOM MX5000 supports dual redundant AC and/or DC power modules
that can be installed in any combination.
The RUGGEDCOM MX5000 is equipped with a screw-type terminal block, which
provides power to both power modules. The terminal block is installed using Philips
screws and compression 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
Removing Power Supply Modules (Page 30)"
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.
NOTICE
• In an AC/DC power arrangement, the placement of the AC and DC power
modules 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.
