Document No. 546-14410 Installations Instructions August 16, 2013 Figure 3. Power Trunk Wiring. As a standard grounding procedure, ensure that 3"-5" ground wire is connected directly on the common terminal on the secondary side of the 24 Vac transformer. Figure 4. Dimensions. The installation is complete. Siemens Industry, Inc.

Document No. 546-14410 Installations Instructions August 16, 2013 CAUTION: LCM-OAVS WILL BE DAMAGED/DESTROYED IF OFFBOARD AIR MODULE(S) ARE NOT WIRED CORRECTLY AND POWER IS APPLIED TO LCM-OAVS. Figure 5. Offboard Air Module Wiring. CAUTION: A SEPARATE power supply is required if a 4-20 mA sensor is used. Failure to follow wiring precautions will result in equipment damage. Figure 6.

Document No. 546-14410 Installations Instructions August 16, 2013 Wiring Diagrams CAUTION: The LCM-OAVS Slow Actuation controls 24 Vac loads only. The maximum rating is 12 VA for each DO. For higher VA requirements, 110 or 220 Vac requirements, separate transformers used to power the load, or DC power requirements, use an interposing 220V 4-relay module (540-147). NOTE: Refer to the unit wiring diagrams or consult with the local representative if terminations are missing or different. Figure 7.

CAUTION: See Figure 5 for how to correctly wire the Offboard Air Module(s). The LCM-OAVS has two terminal blocks with terminations numbered identically (terminations 1 through 16). DO NOT get these mixed up with each other. If the LCM-OAVS is not connected as shown, it is not resistant to electrical surges.
