6.1.2. Intrinsically Safe Runtime Extension For Hazardous Areas
If the RigRat is to be charged or powered in a hazardous area, then an intrinsically safe (I.S.) barrier
box is necessary. Use P/N: W03-3018-000, and connect it to the IS CHG HAZARDOUS port.
Note: The intrinsically safe line power is only providing runtime extension.
1. Requirements:
a. W03-3018-000 I.S. barrier, 110~230VAC/50~60Hz IN, 23.5VDC/1.15W OUT
b. W03-2168-000 I.S. barrier extension cable, 100 m, 3-pin plug
