6.1 Preparation
Prior to installing the transmitter, verify that the transmitter is rated for
the area where it will be installed. Consider the available power, the
ambient temperature, whether it is a Hazardous Area (Explosive
gasses) or an Ordinary Location, and whether it is to be wall- or pipe-
mounted. If the markings on the transmitter received are not
consistent with the conditions of the area in which it must be installed,
contact Customer Support.
In addition to the warnings and cautions in this section (section 6),
refer also to the General Safety Guidelines in section 3.
6.1.1 Transmitter Power Requirements
The AC version of the transmitter can accommodate an input voltage
of 100
– 240 volts AC, 50/60 Hz, and requires 25 watts of power.
The DC version of the transmitter can accommodate an input voltage
of 18
– 36 volts DC and requires 25 watts of power.
Refer to the fuse label in the transmitter or Appendix A for input power
fuse ratings.
Only replace fuses with the fuse type indicated on the label inside of
the transmitter.
WARNING
Electrical shock hazard. Always disconnect power source prior
to removing fuses. Failure to remove power source may result
