Omega Engineering SOLID STATE RELAYS SBG22445 - Manual (Page 2)

•
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.
