Large System Installation and Commissioning

Connect each DC rectifier to its associated AC outlet and set the breakers 
in the AC power panel to ON.

Turn the rectifiers ON one at a time. Wait 10 seconds between each 
rectifier. 

Note: Power up the Core columns last.

On the DC power source for each column, replace the distribution fuses 
or set the distribution breakers to ON. Do the Core columns last.

Set the blower unit breaker switch ON (the far left breaker in the rear of 
the pedestal).

Set the blower unit switch in the front of the pedestal to ON. Verify that the 
fan is running. On initial power-up, the blower rotates slowly. As the 
system heats up, the cooling fans turn faster.

Set the power supply switch in each module to ON. The green light will 
turn on after a few seconds. 

Note: If the module is equipped with a ringing generator, set the breakers 
or switches for both the power supply and the ringing generator to ON. 
The green LED on a ringing generator normally takes up to 90 seconds to 
light.

Repeat step 1 through step 5 for each column in the system. Start with 
Column 2 and continue until power is turned on in all the columns. Do the 
Core columns last. 

If a problem occurs in any of the following steps, resolve 
that problem before continuing.

Perform the following tasks for each column
