Installing The TLS-450PLUS Console
Mounting The Console
The TLS-450PLUS has the same mounting bolt pattern and approximate weight as the TLS-350. One major
consideration for the placement of the TLS-450PLUS is that the screen is at eye level so it can be seen and
touched (see Figure 1).
The TLS-450PLUS doesn’t have pre-assigned slots for the Module bay modules so use any of the four slots to
accommodate intrinsically safe (USM) or non-intrinsically safe (I/O, MDIM, etc.) modules (see Figure 2). Since the
Module Bay modules can be installed in any of these 4 slots, install them where it makes the most sense for
conduit connections. Caution! USM wiring inputs are intrinsically safe and conduit containing this wiring must
attach to the knockouts above or below the slot in which the USM module(s) is installed.
Never use a drill to open up knockouts. This could potentially result in metal filings getting into the console. It’s
much easier to just knock out the pre-punched slugs in the console anyway. Remember only knock out the smallest
size needed. The console is pre-punched for 3/4” and 1” for Module Bay slots, but up to 1-1/4” may be used if
needed. Again, if 1-1/4” conduit is needed, use a punch, not a drill to remove the knockout. Make sure that the
conduit fitting ring is tight.
Connecting Wiring To Console Modules
Refer to the appropriate Control Drawing on page 2 to identify modules that can be installed in the console and
the designated devices that can be connected to them.
Try not to have too much wire in the console. Pull unneeded wire back into the wiring trough and loop it neatly.
Warning! only intrinsically-safe wiring can enter a USM module slot knockout.
1. Make sure to terminate the ground shields to the ground lug on the module. The other end at the probe or
sensor is NOT grounded.
2. Write in the device name for each wire connection on the connector block in the module’s wiring label attached
to the inside of the door.
3. Make sure to loop the wire neatly under the lip of the module. This will keep wires from interfering with the door
when it closes.
Installing I/O, MDIM Or LVDIM Modules
Avoid too much wire in the console. Pull unneeded wire back into the wiring trough and loop it neatly.
1. Figure 2 illustrates acceptable non-intrinsically safe module positions in the Module Bay of the console. After
installing the I/O, MDIM or LVDIM module, remove the connector from the module, loosen the screw, insert the
wires and tighten well.
2. Write in the device name for each wire connection on the connector block in the module’s wiring label attached
to the inside of the door.
3. Loop the wire neatly under the lip of the module.
4. Close the right door and replace and tighten the top and bottom screws on the right side of the door.
