TOWER CONFIGURATION
The tower configuration allows the user to install the ED-XFR in the up-right
position. The tower stands are provided with the UPS. The tower stand ex-
tenders are provided with the ED-XFR. WARNING: Use two or more people
when installing the ED-XFR. USE CAUTION: The ED-XFR is extremely
heavy. Use the appropriate number of personnel when installing the UPS
system.
1. Once the location of the ED-XFR has been determined, place the tower
stands in the desired location.
WARNING: The ED-XFR must be installed in the proper up-right position.
Once the ED-XFR is placed in the tower stands, the vent holes on the side
panels must be facing upwards to provide proper ventilation.
2. Slide the ED-XFR into the tower stands. Make sure that the ED-XFR is
stable.
3. The name plate panel can be rotated to read in the up-right position. Rem-
ove the front panel from the ED-XFR. On the backside of the front panel,
push the name plate panel outwards, the panel will pop out. Rotate the
name plate panel counter clockwise so that it reads in the upright position.
Re-install the front panel on the ED-XFR.
CONNECTING THE STEP DOWN TRANSFORMER TO THE UPS
WARNING: Qualified Service Personnel ONLY must perform the Installa-
tion and Servicing of these ED-XFR.
1. Before connecting to the input / output terminals read all of the Cautions
and Warning, then observe the following:
a) Ensure that the UPS is turned off and not connected to the AC sour-
ce or the battery source before any connections are made.
b) Calculate the power consumption of the load to ensure that an over-
load condition does not occur.
c) Ensure that the terminal block screws are secured after connecting
the input / output wires. The terminal block screws should be torque
to 18±2Kgf.cm (requires a 3/16" flat-head screwdriver).
d) Ensure that the ED-XFR and the UPS are properly grounded.
2. The input power for the ED-XFR must be single-phase in accordance with
its rating label and the specifications in this manual. The ED-XFR's input
voltage setting must be the same as the UPS's output voltage setting.
NOTE: The AC inputs of these Step Down Transformers are ONLY intend-
ed to be connected to the output of their respective UPS models.
The ED5000RT-XFR and ED6000RT-XFR come with an attached #10 AWG
input power cord. Connect the input power cord to the output terminal block
on the UPS. The AC inputs of these Step Down Transformers are ONLY
intended to be connected to the output of their respective UPS models. Do not
use extension cords, adapter plugs, or surge strips. The installation of up-
stream and downstream protective devices is highly recommended when the
UPS system is connected to the mains and the load.
