2.2 Mounting
When the DL423 is specified with Table II = 5, the Remote Connector Assembly is
supplied loose for connection of the conductivity cell cable to the DL423 module.
Table 2-2 gives the mounting procedure.
ATTENTION:
The Blue and Brown leads (for 4973/4905 cells with integral and Quick Disconnect
cables only) are shipped with a short piece of shrink tubing around the exposed
ends for ESD protection of the EEPROM device. During wiring and installation
proper ESD protection is required to ensure that the memory device is not damaged.
Table 2-2
Remote Mounting Procedure for Conductivity Cells
Step
Procedure (Refer to Figure 2-3 and Figure 2-4)
1
Turning counterclockwise, remove strain relief/cover combination from the
remote connector assembly.
2
Remove the protective plastic bag from the end of the cell cable.
3
Loosen and remove compression cap from strain relief fitting. Carefully push
cable end through cap and strain relief fitting so that these parts are strung
back along cable jacket.
4
Connect cable leads , see Figure 2-3
Note: for highest accuracy in high purity water applications, the remote cable
length must not be modified.
5
Slide cover along cable and tighten by hand onto the remote connector
assembly.
6
Slide cap along cable and tighten onto cable jacket with small wrench until
cable cannot slide within strain relief rubber bushing.
7
Remove red protective vinyl boot from opposite end of connector assembly.
8
Apply a thin film of silicon grease to the ID of electronics module’s remote
mounting cavity.
9
Plug remote connector assembly into DL423 module aligning polarity tab of
module housing and mating groove on connector.

Secure Electronics Module with Wall, Pipe, or DIN Rail Mounting
Mount bracket with clips facing forward, smaller clip on top and larger clip on
bottom.
Wall:
Use one of three through-holes to secure to wall.
Pipe:
Feed hose clamp through two slots and secure to pipe.
DIN rail:
Attach the appropriate DIN rail clip to the mounting bracket:
“U” DIN rail—use metal clip and shorter screw (8 mm)
“G” DIN rail—use gray clip and longer screw (10 mm)
Clip can be rotated for horizontal or vertical DIN rails. Push electronics
module onto the remote mounting bracket until it snaps into position.
