Connecting Power

The RUGGEDCOM RSG2488 supports dual redundant AC and/or DC power supplies
that can be installed in any combination.
The RUGGEDCOM RSG2488 can be equipped with either a screw-type or pluggable
terminal block, which provides power to both power supplies. The screw-type
terminal block is installed using Phillips 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.
Electrocution hazard – risk of serious personal injury or death
The device may have two power supplies equipped, which may be connected to
separate power sources. Make sure all power sources are off before servicing the
power supply terminals.
Electrical hazard – risk of damage to equipment
Do not connect wiring to unused power supply input terminals. For instance, if a
Low DC power supply is installed in the PS1 slot, do not connect the PS1 High AC/DC
terminals to a power source.

placement of the AC and DC power supplies is not slot-dependent. However, if a
high AC/DC power supply is installed in slot PS1, the high AC/DC wiring must be
connected to the high terminal block PS1 terminals. If a low DC power supply is
installed in slot PS1, the low DC wiring must be made to the low terminal block
