Two types of fan-cooled, hot-pluggable Access Power Rectifiers are available. 

• 

APU48 – 48 V, 720 W, (120 - 240 V AC) 

• 

APR48 – 48 V, 1500 W, (208 - 240 V AC) 

There are three status indicator LEDs on the Access Power Rectifier front panel (Power On, 
Urgent Alarm and Non-Urgent Alarm). 

Details about replacing a rectifier can be found in Chapter 7. 
 

 

 

"

  Power On LED (Green) – indicates that the rectifier is 

powered. 

#

  Non-Urgent Alarm LED (Yellow) – indicates non-critical 

conditions, such as: 

• 

Rectifier in power/current limit mode 
(This normally happens for a short period of time 
when the batteries are recharging.) 

• 

Rectifier operating in temperature turndown mode, 
because of high ambient temperature or low AC 
supply voltage 

$

  Urgent Alarm LED (Red) – indicates critical fault 

conditions, that require urgent attention, such as: 

• 

Rectifier failed

 

• 

Rectifier shut down

 

• 

AC supply failed (green LED off)

 

• 

Very high AC supply voltage

 

• 

DC overvoltage
