Connecting AC Power
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
Section 4.3, “Installing/Removing Power
.
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 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.
• 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 circuit breaker for each power module module.
• Equipment must be installed according to applicable local wiring codes and standards.

Connecting AC Power
To connect AC power to the device, do the following:
DANGER!
Electrocution hazard – risk of death, serious personal injury and/or damage to the device. Make sure
the supplied cover is always installed over high voltage screw-type terminal blocks.
CAUTION!
Electrical hazard – risk of damage to equipment. Do not connect AC power cables to a DC power supply
terminal block. Damage to the power supply may occur.
NOTE
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 screws, which must be
removed to make connections.
1. Connect the positive wire from the power source to the live terminal on the terminal block.
