A Rectifier can be installed or removed “hot” (i.e. with AC power and DC load applied) with no interruption of Sageon III Power
System service. When removing a Rectifier, there must be sufficient remaining rectifier current capacity to supply the load.
WARNING
Electrical shock hazard
Hazardous voltage can cause death or serious injury.
240 VAC may be present at the Rectifier Switch Assembly and AC Backplane.
Always use insulated tools.
Installing a Rectifier:
1.
Remove a Rectifier from its shipping container. Save the packaging materials.
2.
Select a position in which to install the Rectifier.
3.
The optional AC breaker should be in the OFF position.
4.
To install a Rectifier:
1)
Note the voltage and current ratings of the rectifier. Use only 48V rectifiers in the system.
2)
Slide the Rectifier slowly into the Housing until the Rectifier’s rear connectors just engage the Housing connectors. Fully
seat the Rectifier in the Housing to properly engage the connectors.
5.
Check to be sure that the locking mechanism has engaged with the rectifier.
6.
If step 3 was performed: Apply power to the newly installed rectifier by turning on the AC breaker.
7.
Repeat the preceding steps for each Rectifier to be installed.
To commission the Rectifier(s), go to Chapter 3 Commissioning.
Removing a Rectifier:
1.
Optional: Remove power from the Rectifier. Set the breaker to the OFF position.
2.
Lift the locking mechanism.
3.
Grasp the rectifier handle and pull the Rectifier forward 1" to 2".
4.
Grasp the Rectifier and pull it straight out from the Housing. The Rectifier weighs approximately 5 lbs (2.3kg).
5.
Set the Rectifier aside and attach a tag stating its operating status (e.g. OK, needs servicing).
CAUTION
Electrical shock hazard
After removing a rectifier, be careful not to touch the rear connector.
The rectifier will take approximately 1-2 minutes to self discharge. The
red LED will flash during this time.
