Initial Power Up of the System (continued)
Installing the First Rectifier
Step
Install a rectifier in slot one. See Figures 13-2 and 13-2A.
Caution:
a.
Verify that rectifier matches the ac input voltage of the system.
Caution
DO NOT INSTALL 595B OR 595LTB RECTIFIERS INTO 380/400/480Vac systems; they will be damaged.
b.
Verify that the control switch on the front of the rectifier is in the standby (STBY) position; for 595 rectifiers,
verify that the output circuit breaker is also OFF.
When installing a 595LTA or 595LTB rectifier into a single rectifier shelf, remove the Rear Keying Plate and install
the Keying Bracket onto the rectifier. See Figure 13-2A.
1.
Remove Rectifier Rear Keying Plate by removing 2 securing screws. Save Rear Keying Plate for future re-use.
See note below.
2.
Replace the two Rectifier Rear Keying Plate screws onto rectifier and torque to 10 in-lb (1.1 Nm).
3.
Remove Screw "A".
4.
Install Keying Bracket using Screw "A" removed in Step 3, and 2 additional screws supplied with the keying
bracket. Torque to 10 in-lb (1.1 Nm).
5.
Move keying pin on keying bracket to 480Vac position if rectifier is 595LTA.
Note: Rectifier is not keyed in dual rectifier shelf with Rear Keying Plate removed.
Verify Controller
c.
Place the rectifier on the appropriate shelf assembly. Note: Install rectifiers vertically, starting at the bottom
left side of the shelf assembly and working up and left to right (if applicable).
d.
Carefully slide the rectifier toward the rear of the shelf assembly. Push until the unit is seated.
e.
Gently pushing against the right side of the rectifier, use a 5mm (3/16-inch) Allen-head wrench (T-handle) to
turn the recessed locking screw clockwise to secure the rectifier to the shelf.
Note: It is extremely important to fully seat the rectifier into its shelf position. A steady or blinking ALM LED on the
rectifier, after it has been seated and turned on, must be investigated and resolved before it is allowed to
support a load.
Install a rectifier into the top left slot (GPS 4830) or bottom left slot (GPS 4827). Use the hinged front cover of
the rectifier module as a lever to draw the rectifier module into its slot position and lock it into place.
3
Turn ON the AC source circuit breaker and the AC circuit breaker for the installed rectifier.
Turn ON the rectifier's power switch; close its output breaker.
5
Verify that the rectifier turned ON.
6
Verify that the controller and the optional contactor control boards power up.
Note:
Red LEDs will light on BJN and LVBD cards.
7
If the controller has alpha-character capability, verify that the text on the display is in English. If Spanish text is
required, follow instructions on the Help menu to make the change.
