3. SAFETY CONSIDERATIONS
Warning : The use of this equipment 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.
This unit must be powered with AC ( mains ) from 85 to 264 Vac (90 to 370 Vdc) with the high
voltage power supply option or 8 to 28 Vac (9 to 37 Vdc) with the low voltage power supply
option. Verify that the proper power option is installed for the power to be used.
This meter has no AC ( mains ) switch; it will be in operation as soon as power is connected.
Caution: The 85 to 264 Vac (90 to 370 Vdc) mains connector (J1 Pins 1-3) is color coded
Light Blue to differentiate it from other input and output connectors. The 8 to 28 Vac (9 to
37 Vdc) mains connector is not color coded because these voltages are not considered
hazardous.
Do not make signal wiring changes or connections when power is applied to the instrument.
Make signal connections before power is applied and, 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.
Do not operate the instrument in the presence of flammable gases or fumes; such an
environment constitutes a definite safety hazard. This meter is designed to be mounted in a
metal panel.
Verify the panel cutout dimensions and mount according to instructions.
