Rectifier High Voltage Shutdown and Lockout Restart
Procedure
1.
Turn the power to the rectifier off or remove the rectifier, wait 30 seconds or more (until the LEDs on the rectifier extinguish),
then turn the power to the rectifier on or re-insert the rectifier.
2.4
Rectifier Current Limit
When setting total rectifier current limit, the set point to each rectifier is the total set point divided by the number of rectifiers. For
example, if the system contains five rectifiers and the current limit is set to 150 amps then each rectifier has a current limit set point of
30 amps. If one or more rectifiers are removed or fail it will take several seconds for the individual set points to the remaining
rectifiers to be reset. In the example given, if one rectifier is removed the current limit set point will drop to 120 amps (30 amps times
four remaining rectifiers) until the controller can send updated set points to the remaining rectifiers. This takes a couple
communication cycles (several seconds) after which each rectifier would have a new set point of 37.5 amps for a total of 150 amps.
The total current limit of the rectifiers should not be set such that the loss of the redundant rectifiers will cause this temporary set
point to drop below the actual maximum expected load. If batteries are used on the rectifier output, the batteries should support the
load until the current limit set points can be re-established due to loss of a rectifier.
2.5
Installing Rectifiers
Rectifiers can be inserted or removed with power applied (hot swappable).
NOTE!
Each rectifier module locks into a module mounting shelf by means of a latch located on the bottom of the rectifier.
The latch and rectifier handle are interactive. Pushing the handle up into the rectifier’s front panel causes the latch to extend
to the locking position; pulling the handle down out from the rectifier’s front panel causes the latch to retract. See
CAUTION!
This rectifier contains double pole fusing. Parts of the equipment that remain energized might represent a
hazard during servicing after operation of the fuse. If the rectifiers are connected to a 3-phase system, the neutral line should
also have a fuse.
WARNING!
To prevent damage to the latching mechanism, ensure the handle is in the open position when installing or
removing a rectifier module. NEVER hold the handle in the closed position when installing a rectifier module into a shelf.
Procedure
NOTE!
as this procedure is performed.
1.
Unpack the rectifier.
2.
Place the rectifier into an unoccupied mounting slot without sliding it in completely.
3.
Loosen the captive screw on the rectifier’s handle. Pull the handle down out from the rectifier’s front panel (this will also
retract the latch mechanism). See
4.
Push the rectifier completely into the shelf.
5.
Push the handle up into the rectifier’s front panel. This will lock the rectifier securely to the shelf. Tighten the captive screw
on the handle.
6.
Repeat the above steps for each rectifier being installed in the system.
7.
After the rectifiers are physically installed in the mounting shelf(s), they are ready for operation immediately after power is
supplied to them.
