6.4 Install the Grounding Electrode Conductor
A Grounding Electrode Conductor must be attached to the rear panel using the M5x12 Phillips screw
provided. This connection is required in addition to the power input ground connection to the remov-
able power distribution box.
Install an 8 AWG (10 mm
2
) (75°C copper wire) (minimum size, see NEC 250-5d, 250-81, 250-83, table
250-94) grounding electrode conductor to the nearest effectively grounded metal structural member,
nearest effectively grounded metal water pipe or other grounding electrode in the grounding electrode
system. If the grounding electrode conductor must be protected, non-metal conduit is recommended. If
metal conduit must be used, bond both ends of the conduit to the grounding electrode conductor. Con-
duit is not an acceptable grounding electrode conductor.
A 5mm ring lug for 8AWG wire lug is provided in the accessory box. Other suitable connectors may be
used.
6.5 Install the Internal Battery Pack
To facilitate shipping and installation, the GXT2-6000RT208 ships
without the internal battery installed. Once the UPS is installed in
place, the internal battery pack must be installed.
1. Unpack the internal battery from its shipping container.
2. Lift the battery pack from its container, holding it in the center
of the pack. Do NOT lift the battery pack by grasping the
connector on the rear.
3. Align the battery pack so that the rear connector is nearest the
control panel.
4. Slide in the battery pack until fully inserted.
5. Install the battery door, tightening the two captive screws, finger
tight. The battery door will not install if the battery is not fully
inserted.
6. For tower installation, place the horizontal overlay over the
controls and indicators (see illustration at right).
7. Install the two front bezels.
NOTE
IN BATTERY MODE ONLY, the UPS operates as a separately derived source and contains a
neutral to ground bonding jumper. A grounding electrode conductor (GEC) must be installed
in accordance with national and local wiring codes and regulations.
