5. SAFETY CONSIDERATIONS
Warning: Use of this transmitter 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.
Caution:
• This unit may be powered with AC (mains) from 95-240 Vac ±10% with the worldwide voltage
power supply option, or 12-30 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. This transmitter has
no AC (mains) switch. It will be in operation as soon as power is applied.
• The 95-240 Vac ±10% mains connector (P1 Pins 1-3) is colored Green to differentiate it from
other input and output connectors. The 12-30 Vac or 10-48 Vdc mains connector is colored
Black.
• To avoid dangers of electrocution and/or short circuit, do not attempt to open the case while
the unit is under power. However, signal wiring changes external to the case can be made
safely while the unit is under power.
• To prevent electrical or fire hazard, do not expose the transmitter to excessive moisture.
• Do not operate the transmitter in the presence of flammable gases or fumes. Such an
environment constitutes an explosion hazard.
