Displacer Level Transmitter
2. Using a level, verify that the vessel mounting flange is level
in all directions within 3°.
3. Position the head flange gasket on the vessel flange and gen-
tly lower the displacer into the vessel. To prevent damage to
the stem/spring assembly, avoid tipping the unit or, in any
way, putting lateral forces on the stem.
4. Align the flanges and ensure that the gasket is seated properly.
5. Install the flange bolts and nuts and tighten alternating nuts
in a star pattern. Flange bolting torque specifications are
listed on page 9.
1.2.2 External Chamber
1. Remove the shipping strap and wire assembly which secures
the displacer in the chamber during shipment. This assem-
bly must be removed through the bottom connection or
drain.
2. Using a level, verify that the vessel mounting flanges are
level in all directions within 3°.
3. Align the MODULEVEL process connections with those
on the vessel and attach accordingly, based upon the con-
nection type. Appropriate gaskets and bolting will be
required for flanged connections. Install the flange bolts
and nuts and tighten alternating nuts in a star pattern.
Flange bolting torque specifications are listed on page 9.

QuickStart Wiring
WARNING:
Explosion hazard. Do not connect or disconnect equip-
ment unless power has been switched off or the area is
known to be non-hazardous.
NOTE: Ensure that the electrical wiring to the E3 transmitter is com-
plete and in compliance with all regulations and codes.
1. Remove the cover of the upper wiring compartment of the
transmitter.
2. Attach a conduit fitting and mount the conduit plug in the
spare opening. Pull the power supply wire through the con-
duit fitting.
3. Connect an earth ground to the nearest green ground screw.
See Figure 1. Use a minimum 18 AWG rated up to 85 °C.
4. Connect the positive supply wire to the (+) terminal and the
negative supply wire to the (-) terminal. For Explosion
Proof Installations, see Wiring, Section 2.5.3.
5. Replace the cover and tighten.
