Installing The TLS-450PLUS Console
Connecting The Power Wires To The Console
4. Next strip the ends of the power wires brought into the console. Referring to Figure 5 and to the locations
printed where the power connector attaches to the console, attach the L1, panel ground and neutral wires
(#14 AWG) to the connector block.
5. Next, attach the barrier ground (sized as shown in Figure 5) to the grounding clamp.

6. Plug in the power connector and route the wires so that the cover plate will conceal them when installed.
7. Replace the power connector cover plate using both screws and close the bay door.
8. Reconnect the communication wires to the appropriate comm cards. Wires which are not used on the TLS-
450PLUS should be pulled back into the wiring trough. If necessary, seal up the power trough.
9. Return to the panel, remove the lock-out/tag-out device and label the breaker with the supplied self-adhesive
label. Re-energize the circuit and start up the unit.

• Barrier ground wire requirements:
- For UL/cUL approved systems, use a 12 AWG barrier ground wire
- For ATEX/IECEx approved systems, use a 4 sq. mm barrier ground wire
• Use an ohmmeter to check the electrical resistance between the console’s metal case and the power panel’s earthing
ground wire connection at the ‘known good ground’. It should read less than 1 ohm.
• Connect the power supply wires in the power panel to a separate dedicated circuit.
• Electrical rating of power input - 120 or 240 Vac, 50/60 Hz, 2 A maximum.
• See Figure 1 for locations of power conduit knockouts into the console. Power wiring must enter the console
through designated knockouts.
