Removing an S-DC-PS Power Supply
To remove an S-DC-PS power supply:
1. Ensure that the branch circuit disconnect device is switched to prevent power from being
supplied to the DC power supply.
2. Attach the anti-static wrist strap before handling the power supply module.
3. Switch the circuit breaker on the DC power supply to Off.
4. Remove the clear plastic shield over the terminal studs.
5. Remove the cables from the terminal studs.
6. Disconnect the earth ground stud of the power supply from the earth ground.
7. Unscrew the captive screw to release the power supply from the chassis.
8. Remove the power supply by grasping the handle and pulling it straight out of the chassis.
9. Fasten a coverplate over the empty slot.
Warning: Disconnect all power sources before servicing.
Advertencia: Desconectar todas las fuentes de poder antes de dar mantenimiento.
Warnhinweis: Trennen sie die komplette Stromversorgung, bevor sie das Gerät warten.
Caution: If you want to operate the chassis with only one power supply, be sure to install the
coverplate in place of the removed power supply to contain EMI radiation and ensure proper air
circulation.
Precaución: Si desea trabajar sólo con una fuente de poder, no olvide colocar la tapa en el
compartimiento de la fuente de poder que haya eliminado, para reducir la interferencia
electromagnética y para asegurar una buena ventilación.
