Rnger Hook-up Cheklist for the Rnger (EU) Reserh Limited Reserh Limited Step 1. Estlish type of instlltion (e.g. no. of phses). Step 2. Estlish type of trnsduers (PTs, CTs et.). Step 3. Choose one of the ten following hook-up options: 1) 3-Phse 4-Wire Wye 2) 3-Phse 4-Wire Delt 3) Full 3-Phse 3-Wire Delt (3 element for ll Ph-Ph) 4) 3-Phse 3-Wire Ungrounded (with Equipment Gnd) 5) 3-Phse 3-Wire Ungrounded 6) 3-Phse 2.5-Element Wye 7) 3-Phse 1-Element Wye 8) Single Split Phse 9) Single Phse 10) Unommitted. Those in old re used most frequently. Step 4. Configure instrument for relevnt hook-up. Step 5. Verify physil onnetions long with instrument LED nd PMSreen vetor outputs ( see pp. 1-10 of these notes). Step 6. If required, refer to Phse Angle Summry ( p. 11). Step 7. If vetors or LED onfigurtions do not mth wht is expeted or you see the Suspet Hook-Up messge, refer to possile explntions nd tion to e tken ( pp. 12-13).
