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 873A0250A1A
Y) 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.
