Initial Checkout and Field Installation
a.Remove the cover on the side marked FIELD TERMINALS on
the electronics housing.
b.Connect the lead that originates at the positive side of the
power supply to the terminal marked “+ SIG.” Be sure to
include loop resistance.
c. Connect the lead that originates at the negative side of the
power supply to the terminal marked “–.”
d.Plug and seal unused conduit connections on the transmitter
housing to avoid moisture accumulation in the terminal side of
the housing.
NOTE
If the conduit connections are not sealed, the transmitter should be
mounted with the electrical housing positioned downward for drainage.
Conduit should be installed with a drip loop, and the bottom of the drip
loop should be lower than the conduit connections or the transmitter
housing.
Explosions can cause death or serious injury. The unused
conduit opening on the transmitter housing must be plugged
and sealed to meet explosion-proof requirements.
