Special Cautionary Note
Regarding Input Power Wiring
for Compact Explosion Proof Flowmeters
The compact area of the power wiring compartment located under the Rear Housing Cover does not
permit labeling for connecting the flowmeter to its AC or DC power source. The labeled numbers 1,2 and
3 of connector P8 prompt the user to consult the 1010X-7 installation diagram in Appendix B for wiring
details. To avoid damage to the flowmeter, especially in cases where it is difficult or impossible to consult
the 1010X-7 diagram, the correct power supply wiring procedure and corresponding part numbers are
listed below.
1. In addition to confirming the part number of the flowmeter, it is recommended that the actual power
supply module part number be checked for conformation to the power available in the field. Before
applying power to the unit , you may visually confirm the part number of the power supply by re-
moving the front housing cover.
2. Once the flowmeter’s power supply type has been established and conforms to the available line
power in the field, the P8 power connector can be wired per the table below.
