Installing a Model 10933 or 10934A 300 W DC Power
Supply in a Summit X460 Series Switch
CAUTION
Make sure that the DC power supply circuit is not overloaded. Use proper over-current protection, such as
a circuit-breaker, to prevent over-current conditions. You may use up to a 30-Amp breaker.
To install a DC power supply in a Summit X460 switch, perform the following tasks in the order listed:
1 Prepare the power cables and ground cable by attaching the provided connection lugs to the cables
(see
“Preparing the Cables” on page 251 ).
2 Insert the power supply into the Summit X460 series switch (see “Installing the Power Supply” on
page 251 .)
3 Connect the ground (see “Connecting the Ground Cable” on page 252 ).
4
Have a qualified licensed electrician connect the power supply to the DC source voltage (see
“Connecting the Power Supply to the DC Source Voltage” on page 253 ).
5 Energize the DC circuit.
