Functional Test
The Functional Test consists of three checks: manual
operation, voltage checks, and electrical operation.
Do these checks in the order presented to
avoid damaging the automatic transfer switch.
!
Read all instructions on the Wiring Diagram and labels
affixed to the automatic transfer switch. Note the control
features that are provided and review their operation
before proceeding.
1 – Manual Operation Test
A maintenance handle is provided on the Transfer Switch
for maintenance purposes only. Manual operation of the
transfer switch should be checked before it is energized
(operated electrically).
Do not manually operate the transfer switch
until both power sources are disconnected:
open both circuit breakers.
!
1. After deenergizing both power sources, open the
enclosure door. Locate and the maintenance handle
on the left side of the transfer switch frame. See
Figure 1–4.
2. Grasp the attached maintenance handle and turn it
with thumb and fingers as shown to manually operate
it. The maintenance handle turns the opposite direc-
tion of the weight. Move it up or down as shown to
manually operate the transfer switch. It should operate
smoothly without any binding. If it does not, check for
shipping damage or construction debris.
3. Return the transfer switch to the Normal position.
Note: If Normal and Emergency connections are
reversed this operation is also reversed.
Now continue to 2 – Voltage Checks on next page.
