- Page 3 CS. The DGF5-2 houses a non-isolated universal power supply of 24 – 48 V AC or DC and is equipped with form ‘C’ (3-wire), changeover contacts. The relay operating mode is Pulsed Output Auto Reset. The Ground Fault Current Trip level is factory set at 500 mA;...
- Page 4 Current Level or after three seconds. 2.5 Test The DGF5-2 can be connected to a remote momentary ,voltage free, N.O. button for a relay test (see section 6.2), using the T1 (grey) and T2 (blue) wire leads. A simulated current of 600 mA (1,2 times the Trip Current) replaces the measured current.
- Page 5 OLTAGE The DGF5-2 has a universal power supply input, accepting nominal voltages between 24 and 48 V AC or DC with a -45% / +10% tolerance for AC and -20% / + 10% for DC. The total range of accepted voltages is therefore 15,6 to 52,8 V AC and 19,2 to 52,8 V DC.
- Page 6 Figure 1 for typical field connections. Place the DGF5-2 in a clean dry enclosure. Locate the relay in the vicinity of the isolating device (circuit breaker or contactor) that is protecting the circuit being monitored. Provide maximum clearance between the DGF5-2 and any strong magnetic flux producing devices such as power transformers, autotransformers, control transformers, reactors, high power conductors, contactors and other buswork.
