TYPICAL AUTOMATIC TRANSFER SWITCH

COMMISSIONING PROCEDURES Model Series TS 870

Note: The following commissioning procedures are provided for general information only pertaining to typical site installations and applications. Contact the equipment supplier for further information as may be required.

DANGER!!!!

Arc Flash and Shock Hazard. Will cause severe injury or death.

Do not open equipment until ALL power sources are disconnected

This equipment must be installed and serviced only by qualified electrical personnel utilizing safe work practices and appropriate Personal Protective Equipment (PPE). Failure to do so may cause personal injury or death

CAUTION

Commissioning procedures must be performed by qualified personnel only. Ensure the Automatic Transfer Switch (ATS) Control Isolation Plug is disconnected prior to energizing the supply sources. Manually place the transfer switch mechanism in the neutral position by opening both Utility and Generator Power Switching devices prior to applying power.

NOTE: An optional hand held, plug-in Service Display Module (SDM) is available for the TSC 80 Transfer Controller. The SDM module provides an LCD screen to display additional detailed information on the operation and settings of the TSC 80 controller for simplified servicing/trouble shooting procedures. For detailed information, refer to the separate SDM module instruction manual (PM065).

Pre-Commissioning Checks Prior to Commissioning Agent On-Site (to allow loads to be supplied prior to final commissioning)

1)Verify the system voltage of both sources (i.e. generator and utility) to be applied to the transfer switch are of the correct nominal system value which matches the ATS drawings and the ATS equipment label ratings. If the system voltage is correct, proceed to step 3. If system voltage is incorrect for the rating of the ATS supplied, proceed to step 2.

CAUTION: FAILURE TO RE-CONFIGURE ATS VOLTAGE TO MATCH SYSTEM VOLTAGE

WILL RESULT IN EQUIPMENT MALFUNCTION AND DAMAGE.

NOTE: The factory default system voltage setting for multi-voltage TS 840/870 transfer switches is 480VAC, which will be indicated by a letter “Y” in the voltage code as shown on the ATS model code (e.g. TS 873A0250A1AY) and on a warning tag attached to the isolation plug.

2)To re-configure the ATS for the correct system voltage prior to energization, refer to Appendix B (as attached). For further information, refer to the TSC 80 controller manual supplied with the transfer switch.
