1 INTRODUCTION
All features of the 489 are standard, there are no options. The phase CT secondaries must be specified at the time of order.
The control power and analog output range must also be specified at the time of order. There are two ground CT inputs:
one for the GE Power Management HGF core balance CT and one for a ground CT with a 1 A secondary (may also be
used to accommodate 5 A secondary). The VT inputs accommodate VTs in either a delta or wye configuration. The output
relays are always non-failsafe with the exception of the service relay. The 489PC software is provided with each unit. A
metal demo case may be ordered for demonstration or testing purposes.
