Universal IV - Installation and Operating Instructions
14
CAUTION!
Before using Intrinsic Safety Barriers, read manufacturer's
instruction for barrier operation.
The Universal IV has a built-in current limiter which holds the
signal current to a maximum of 28 mA.
The signal connections are made to the three-terminal block on
the front of the chassis. Due to the low power consumption of the
instrument, the wiring need only be light gauge (e.g. 20 AWG).
Shielded twisted pair cables are recommended.
Integral units are pre-wired to the sensing element at the
factory. Figure 2-7 shows the wiring of the integral unit.
See Figure 2-8 for wiring connections of the remote unit. The
cable from the sensing element is connected to the terminal strip
below the instrument chassis. The cable connections are sensing
element (prb) or center wire (cw), ground (gnd), and shield (shd).
