!
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.
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.
