Power to the
Transmitter
When connecting power to the 1400A/1400S transmitters, refer to
installation wiring drawing
.
Note
To meet the requirements of CSA 1010.1, an external switch or
circuit breaker must be installed to allow the power source to be
disconnected from the gauge. In addition, protective bonding (grounding)
must always be provided even if a DC power source is used.
▲
With AC power, the 1400A and 1400S transmitters are designed to operate
on 100–240 Vac, at an input frequency of 50/60 Hz. The same system
configuration can be directly wired to either 115 or 230 Vac. The
maximum input power requirement is 12 VA when all options are present.
AC Power
Connections are shown in the table below.

DC Power
Note
To meet the requirements of CSA 1010.1, the input DC terminals
must be supplied from an SELV (Safety Extra Low Voltage) source.
▲
With 24 Vdc power, the 1400A and 1400S transmitters are designed to
operate on 20–28 Vdc. The maximum input power requirement is 12 VA
when all options are present.
Connections are shown in the table below.
