GE IP-QUADRATURE Digital output module

1 Strip outer insulation from both ends, exposing the braided or spiral wrapped shield. Do not cut the shield on the end nearest to the Load Sharing Module. Cut off the shield on the end away from the unit. 2. Use a sharp, pointed tool to carefully spread the strands of the shield. 3. Pull the inner conductors out of the shield. Twist braided shields to prevent fraying. 4. Connect lugs to the shield and to the control wires. Number 6 slotted or round crimp-on terminals are used for most installations. Connect the wires to the appropriate terminals on the module. Installations with severe electromagnetic interference (EMI) may require shielded wire run in conduit, double shielded wire, or other precautions

Current Transformers

 Power source current transformers should be sized to produce 5 A secondary current with maximum generator current (3–7 A secondary current at full load is acceptable). CT burden is 0.1 VA. To prevent lethal high voltage from developing on leads to the terminals, the Load Sharing Module contains internal burden which must be connected across the power source current transformers whenever the unit is running. Ammeters may be installed on the leads from the current transformers. Connect phase “A” CT to terminals 4 and 5. Connect phase “B” CT to terminals 6 and 7. Connect Phase “C” CT to terminals 8 and 9. Observe correct phasing as shown in the plant wiring diagram

Load Sharing Lines, Droop, and Auxiliary Contacts 

The droop contact for selecting droop or isochronous operation is wired in series with the circuit breaker auxiliary contact between terminals 13 and 14. When both the droop contact and circuit breaker auxiliary contact are closed, the Load Sharing Module is in the isochronous load sharing mode. In this mode the internal load-sharing-line relay is energized, the droop signal is disabled, and the load matching circuit is connected to the load-sharing lines, permitting isochronous load sharing.
