Conditions for Safe Use
1. Shall be powered only by C-sized lithium primary cell type TL-4920/VE
manufactured by Tadiran or Emerson Part Number A0702PPU.
2. HART Terminal Entity Parameters:
Uo = 5.84V, Io = 116mA, Po =329mW, Co = 0.1µF, Lo = 5mH;
Ui = 5.27V, Ii = 5mA, Pi = 6.6mW, Ci = 13 µF, Li = 0.022mH
3. The device may be configured using the HART terminals only by 375, 475, or TREX
field communicators.
4. Under certain extreme circumstances, the non-metallic parts incorporated in the
enclosure of this equipment may generate an ignition-capable level of electrostatic
discharge. Therefore, the equipment shall not be installed in a location where the
external conditions are conductive to the build-up of electrostatic charge on such
surfaces. In addition, the equipment shall only be cleaned with a damp cloth.
5. The device shall be installed on an earthed metal frame.
Note
Battery may be replaced in hazardous locations. Only replace battery with Tadiran Part
Number TL-4920/VE or Emerson Part Number A0702PPU.
