1. Safety Warnings
Warning: Use of a device in a manner other than specified may impair the protection of the device
and subject the user to a hazard. Visually inspect the unit for signs of damage. If the unit is
damaged, do not attempt to operate it.
Caution:
Meters, transmitters and the LTNET485 DIN-rail Ethernet-to-serial device server may be powered
with AC (mains) from 85-264 Vac with the high voltage power supply option, or from 12-32 Vac
or 10-48 Vdc with the low voltage power supply option. Verify that the proper power option is
installed for the power to be used. These products have no AC (mains) switch. They will be in
operation as soon as power is connected.
• The 85-264 Vac or 95-300 Vdc (mains) connector is colored Green to differentiate it from
other input and output connectors. The 12-32 Vac or 10-48 Vdc connector is colored Black.
• For safety reasons, do not make signal wiring changes or connections when power is applied
to an instrument. Make signal connections before power is applied. If reconnection is required,
disconnect the AC (mains) power before such wiring is attempted.
• To prevent electrical or fire hazard, do not expose the instrument to excessive moisture or
temperature.
• Do not operate the instrument in the presence of flammable gases or fumes, as such an
environment constitutes an explosion hazard.
• Meters are designed to be mounted in a metal panel. Verify the panel cutout dimensions, and
mount according to instructions.
• LTE transmitter and the LTNET485 DIN-rail Ethernet-to-serial device server are designed to be
clipped to a 35 mm DIN rail.
