Caution:
The institution should follow local governing ordinances and recycling
instructions regarding disposal or recycling of filter and device
components or end of life of the product.
4.
Dispose of the power supply as required by WEEE Directive.
5.
Position the new power supply on the four mounting bosses, with the GND ter-
minal at the lower right near the AC power inlet (
Figure 10-32 on page 10-44).
6.
Attach the power supply to the mounting bosses with the four screws. Tighten
the screws to 0.4 to 0.6 N-m (3.5 to 5.3 lb-in).
7.
Connect the cables to the new power supply as follows ( Figure 10-32 on
page 10-44):
a.
Connect the ground cable from the equipotential stud to the GND terminal.
Make sure the connector is fully seated on the terminal, and that the heat
shrink on the adjacent capacitor does not get caught under the connector.
b.
Connect the AC power inlet wire assembly to the 3-pin CON1 connector.
Make sure the connector latch engages.
c.
Connect the power supply output cable to the 4-pin CON2 connector. Make
sure the connector latch engages.
Note: If a cable tie previously secured the AC power inlet wire assembly to the
power supply mounting boss (see page 10-44 ), install a new cable tie at the same
position. The cable tie should cause the wires connected to CON1 to form an arch
approximately 4 cm (1.5 in) above the connector. Trim off the end of the cable tie.
