Notes:
o
The enclosure of all HF6 models is designed to be installed in the horizontal position
o
Cable grips are located at the bottom of the enclosure (models with 85 to 264 VAC supply voltage have 2
cable grips)
o
Conduit adapters are located on top of the enclosure (models with 85 to 264 VAC supply voltage have 2
conduit adapters)
o
The factory default setting for the dew point calculation is the frost point below freezing
o
The same terminal block is used for either the Modbus interface or the RS-485 interface. A MODBUS
network and a RS-485 network are physically identical and differ only in the communication protocol
being used. The default communication protocol used with the RS-485 interface is RO-ASCII. When
ordered with the MODBUS interface, the transmitter is configured by the factory to use the MODBUS
ASCII communication protocol
