4.0POWER AND SIGNAL

AC versions of the voltmeter are factory-set for 115 Vac in the USA and 230 Vac in Europe (using C1 option) ±15% operation. DC versions are preset for 9-32 Vdc or 26-56 Vdc operation. It is not possible to change the meter from 9-32 Vdc to

26-56 Vdc or vice versa. Different static inverters are installed by the factory. Refer to Safety Considerations prior to connecting power.

4.2POWER AND SIGNAL CONNECTIONS

Use shielded, twisted cable for the input signal, with the shield terminated to analog ground at the connector. Both analog and digital ground are internally connected and should not be connected externally. For proper grounding, connect the low signal to SIG LO (signal low).

A jumper at S3-A (Figure 5-2 Main Board) ties SIG LO to ANA GND (analog ground) internally. The common for digital inputs/outputs is connected to DIG GND (digital ground). This allows current to flow only in the digital ground and prevents IR drop in the analog ground that would be misread as a signal. A small voltage may exist between analog and digital grounds on connector J1.
