E.3 Wiring the signal connections for the weatherproof version
Refer to Figure 88 on page 69, and complete the following steps to make the proper wiring connections:
WARNING!
Cable entries of an approved flameproof design are required. These must be installed installation category
achieved.
1. Install the first cable entry device in accordance with the manufacturer’s instructions.
Note: If installation of the cable entry device is only partially complete, Panametrics recommends tagging the device to
ensure the safety of subsequent users.
a. Thread the cable gland entry body into the XMO2 port closest to the terminal blocks.
b. Route the 4-wire power/analog output cable through the cable gland as shown in Figure 89 below.
c. After terminating the shield as shown, assemble the three gland pieces together and tighten the gland to secure the
cable and the shield.
IMPORTANT:
The cable shield must be terminated in the cable gland as shown in Figure 89 below.

2. Remove the screw that secures the EMI filter board to its standoff. Then, pull the board from its socket to access the TB3
connector, and loosen the terminal screws on the TB3 connector.
3. Connect the power leads:
CAUTION!
Connecting the +24 VDC line (red) lead to any terminal except TB3-1 will damage the XMO2.
a. Insert the 4-wire cable +24 VDC line (red) lead into pin TB3-1 and tighten the screw.
b. Insert the 4-wire cable 24 VDC return (black) lead into pin TB3-2 and tighten the screw.
4. Connect the analog output leads:
a. Insert the 4-wire cable + 4-20 mA (white) lead into pin TB3-3 and tighten the screw.
b. Insert the 4-wire cable – 4-20 mA (green) lead into pin TB3-4 and tighten the screw.
5. Carefully plug the EMI filter board back into its socket, and screw the EMI filter board to its standoff.
