Servicing Precautions
Removal of Pioneer Multi-Output Supply
1. Remove the left rear cover of the power supply frame, as viewed from
the rear, to expose the wiring connections at the rear of the Multi-
Output power unit. See Figure 4-3.
If this is the upper power supply in a redundant power system, also
remove the left rear cover of the lower power supply.
2. Disconnect the two connectors that plug into the jacks at the top of the
left rear compartment. (Hint: To release the connectors, squeeze the
near and far side tabs on the large connector, and the left and right side
tabs on the four-wire connector.
If this is the upper power supply in a redundant power system, also
disconnect the corresponding two plugs in the lower power supply
frame.
3. Unplug the small multiwire connector that connects to the top of the
circuit board containing the power supply indicator LEDs.
4. At the upper right of the compartment, on the rear of the power supply
unit, remove the terminal block cover (if present) and disconnect the
blue and brown wires from the terminal block. The green/yellow wire
may be left in place.
5. Push the two wires back through the hole into the frame cavity, so they
will not interfere when the sled is removed.
