Field Communicator Connections

The Power Module needs to be installed in the device for the Field Communicator to interface with the 708. This transmitter uses the Green Power Module; please order model number 701PGNKF. Field communication with this device requires a HART-based Field Communicator using the correct 708 DD. Field communicator connections are located on the power module. The Power Module is keyed and can only be inserted in one orientation. Refer to Figure 1-3for instructions on connecting the Field Communicator to the 708.

Electrical	Power Module
	The Rosemount 708 Wireless Acoustic Transmitter is self-powered. The
	power module contains one “D” size primary lithium/thionyl chloride battery.
	Each battery contains approximately 5.0 grams of lithium. Under normal
	conditions, the battery materials are self-contained and are not reactive as
	long as the battery and the power module are maintained. Care should be
	taken to prevent thermal, electrical, or mechanical damage. Contacts should
	be protected to prevent premature discharge.
	Use caution when handling the power module, it may be damaged if dropped
	from heights in excess of 6.10 m (20 ft).
Environmental	Verify that the operating atmosphere of the transmitter is consistent with the
	appropriate hazardous locations certifications.
	Temperature Effects
	The transmitter will operate within specifications for ambient temperatures
	between -40 and 85 °C (-40 and 185 °F).
