Stand-alone ABB Zenith automatic trans-
fer switches are not designed to be oper-
ated manually under load. In the event the
automatic transfer switch has to be oper-
ated manually, with no power available,
please follow these steps:
1. Verify all voltage input sources to the
automatic transfer switch have been re-
moved with proper LOTO procedures
followed. Consider stored energy sources
as well.
2. Verify all load connections have been
removed with proper LOTO procedures
followed. Consider stored energy for
load equipment as well.
3. Insert the manual handle into the de-
sired port of the automatic transfer
switch (Fig. 3.4).
5. Verify that the rotation of the handle
has come to full rest with markings
clearly visible in the status window.
Be sure to rotate the handle until no
further travel is permissible, but DO NOT
over-rotate. Over-rotation of handle may
lead to equipment damage. Remove the
manual operating handle and return it to
the proper storage location before
conducting any electrical transfers.
