Connecting Power

The RUGGEDCOM RSG2488F supports dual redundant AC and/or DC power supplies
that can be installed in any combination.
The RUGGEDCOM RSG2488F can be equipped with either a screw-type or pluggable
terminal block, which provides power to both power supplies. The screw-type ter-
minal 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, reli-
able 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 sep-
arate 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.

CAUTION
In a high AC/DC and low DC (24/48 V) power supply arrangement, the place-
ment 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 con-
nected to the high terminal block PS1 terminals. If a low DC power supply is in-
stalled in slot PS1, the low DC wiring must be made to the low terminal block
