Failure to observe this warning could result in serious injuries or damages. GROUP CAPACITANCE INDUCTANCE A & B 0.1 .F 3 mH C 0.2 .F 10mH D 0.3 .F 20mH Example: Typical values of capacitance for a twisted pair of copper wires is between 20 and 60 pF per foot. Using the maximum value of 60pF/ft, Groups A & B could have a run of 1500+ feet with safety. Inductance of a typical twisted pair is between 0.10 and 0.20 .H/ ft, thus making a cable run in this example essentially determined by the capacitance. Fig. 2.

Unit Mounting Detail • Non-intrinsically safe wiring cannot be run in conduit or open raceways together with intrinsically safe wiring.** • Refer to Fig 6 for detailed connection to terminal studs. All hardware, including terminal lugs, is supplied with unit. • Fusing of the solid-state relays to be in accordance with Fig. 1. Fuse F1 to be 6 amps slo-blo, 120 VAC for 120V line voltage; 250 VAC for 240 V application. **Note: All intrinsically safe wiring to intrinsically safe solid-state relays must be segregated from non-intrinsically safe wiring.
