************* ***** DANGER ***** ************* Be certain the operation selector switch on the front of the A.T.S. Control is in the “stop” position and the main power switch “off”. For your own protection, verify these important safety precautions yourself with reliable instruments before proceeding. FIGURE 5 A.C. ELECTRICAL CONNECTIONS ************* ***** WARNING ***** ************* A FUSED DISCONNECT/CIRCUIT BREAKER MUST BE INSTALLED BETWEEN THE GENERATOR AND THE A.T.S.
All three neutral connections are made to the appropriate neutral lugs. These lugs have been prewired common in the A.T.S. A neutral to ground bond has also been installed in the A.T.S. panel. If your system requires an isolated neutral this bond, a copper jumper strap, should be removed. If this jumper strap is removed remember to properly ground the Automatic Transfer Switch using the grounding lug provided.
CLOCK NOTES: This seven day exerciser clock has seven additional program cycles available. Always keep in mind the odd number turns the unit on and the even number shuts the unit off. (i.e. (3 on, 4 off) (5 on, 6 off) etc.) This completes your installation and unit testing. ALWAYS leave the system in automatic mode unless servicing the unit. For automatic operation, keep both the generator set and transfer selector switches in the “AUTOMATIC” position.
