Intrinsically Safe Wiring
The Intrinsically safe wiring is the same for all type of
dispensers. The wires from the top end of a potted nipple
should be connected to the TS-DTU module and from the
bottom end to the TS-VFM and TS-VPS. These wires
connect intrinsically safe devices (TS-VFM and TS-VPS) to
the associated apparatus (TS-DTU) and therefore must be
protected in non-hazardous area where TS-DTU is
located.
