Ordering; Other Accessories - GE 489 Instruction Manual

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 Multilin HGF core balance CT and one for a ground CT with a 1 A secondary (may also be used to accom-
modate 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.
