CABLE INSTALLATION

WIRING PREPARATION

!CAUTION

Please read this section thoroughly before attempting to install wiring to this unit.

Be sure that the unit is not connected to any AC mains power source or UPS before installing any wiring to this unit. This should be installed by a qualified/certified electrician.

For access to terminal blocks, see diagrams on page 4.

NOTE

The 120V loads need to be balanced on the UPS output. To do this, when connecting 120V equipment to the Maintenance Bypass, start at one end of the output modules and fill in toward the other end. Load balancing must be performed with the UPStation GXT6000T - 208X and 240X. It is not required on the GXT6000T-208 because the unit has no 120V output.
