Task 3 - Connect the AC Supply Cable(s)
Ignore this task if the APS has pre-fitted ac cord(s).
For APS12 models only, repeat the following steps for the second rectifier shelf.
If the APS dc power system is to be installed in a location where the ambient temperature
may rise above 50ºC (122ºF), then 105°C rated cable rated cable must be used for the ac
connections.
Step 1 - Check ac rating of the APS
See the diagram on page
or the diagram on page
for location of ac rating label.
