Wiring Fixed Terminal Figure 3-1. CageClamp Termination Blocks (example photos) Most of the EGCP-2 control’s terminal blocks are designed to be removed by hand. After EGCP-2 input power is disconnected, the terminal blocks can be removed one at a time by pulling them straight out. Care should be taken not to pull the plug out at an angle as this will fracture the end terminal.
EGCP-2 Engine Generator Control Package NOTE Do not tin (add solder to) the wires that terminate at the EGCP-2 terminal blocks. The spring-loaded CageClamp terminal blocks are designed to flatten stranded wire, and if those strands are tinned together, the connection loses surface area and is degraded.

When the Mains PT Disconnect changes state, the EGCP-2 has to measure less than 40 Vac on the Mains/Bus PT input (terminals 40 and 41). If the EGCP-2 measures greater than 40 Vac after the Mains PT Disconnect command was given, the EGCP-2 senses this as a fault and will not synchronize.
3. K1 and K2 relays should be connected as normally open contacts NOTE Because the same EGCP-2 input is used to sense both the utility and local bus voltages, the two PT signals must be identical in configuration (WYE or Delta), phase (A-B or A-N), and amplitude for correct input readings.
Required PT Wiring Relationships The EGCP-2 control uses its programmed PT-Ratio setting to calculate and compare all PT input voltages. Thus, the EGCP-2 control requires the following generator, utility, and plant-bus PT relationships. Refer to Figures 3-9 and 3-10. EGCP-2...
