Receiving, handling and storage
Read these safety instructions
carefully before using this product!
Receiving and handling
Upon receipt, carefully inspect the transfer
switch for damage that may have occurred
during transit. If damage is evident, or there
is visible indication of rough handling,
immediately file a damage claim with the
transportation company, and notify your
local ABB sales office.
Do not remove the shipping packaging until
ready to install the switch.
Storage
If the unit will not be placed into service
immediately, store the transfer switch in its
original package in a clean, dry location.
To prevent condensation, maintain a uni-
form temperature. Store the unit in a heated
building, allowing adequate air circulation
and protection from dirt and moisture.
Storing the unit outdoors could cause harm-
ful condensation inside the transfer switch
enclosure.
HAZARD OF EQUIPMENT
OVERTURNING
When moving with a fork lift, do not
remove the shipping packaging until the
device is in its final location.
Failure to follow this instruction may
result in personal injury or equipment
damage.
Warning
Indicates a hazardous situation that,
if not avoided, could result in death or
serious injury.
Danger
Indicates a hazardous situation that,
if not avoided, will result in death or
serious injury.
HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective
equipment and follow safe electrical work
practices.
• This equipment must only be installed and
serviced by qualified electrical personnel.
• Before performing visual inspections,
tests, or maintenance on the equipment,
disconnect all sources of electric power.
Assume that all circuits are live unless they
are completely de-energized, tested,
grounded, and tagged. Pay particular at-
tention to the design of the power system.
Consider all sources of power, including
the possibility of backfeeding.
• Disconnect all sources of electric power
before removing or making source side or
load side connections to the transfer
switch.
• Always use a properly rated voltage
sensing device at all line and load connec-
tions to confirm transfer switch is discon-
nected from all live electrical sources.
• Turn off power supplying transfer switch
before doing any other work on or inside
switch.
Failure to follow these instructions could
result in death or serious injury.

Operational types
In this table you can find the differences
of the automatic transfer switch open
and delayed transition operation types.
Due to the different transition types, there
are variances with HMI and on wiring of I/O
contacts.
HMI
The HMI is the control interface
(Human Machine Interface) of the ATS.
Zenith ZTS T-series has a color touch
screen LCD HMI with push buttons.
The HMI is used for configuring
parameters for automatic operation.

Automatic configuration
Auto configure is the first step to take
after the panel is initially energized. This
function recognizes the electrical system,
then automatically sets all the system
parameters: system voltage, frequency,
and phase sequence.
Follow the steps in the figure on the HMI
to run auto configure. The ATS must have
at least one source available to complete
this step.
To put your ATS into Auto mode, confirm
the slide switch is in “AUTO” before the
enclosure door is closed. This slide switch
overrides the Auto/Manual mode set from
the HMI. To place the ATS controller in
AUTO mode through HMI screen, set
"Automatic mode" to "ON" in the
operations menu.
Confirm the ATS is in Auto mode by
validating that the “AUTO” LED above and
to the right of the LCD screen is solid
green.

padlocking the automatic transfer switch; The handle
has to set standby slot (not in use), after that the slide
switch will move to the Locking mode automatically
and the switch is allowed to be padlocked.
The operation mode is selected by using
the slide switch (Hand - Locking - AUTO)
located on the front of the automatic
transfer switch (ATS).
• Hand-position = Manual mode, enabling
emergency manual operation using the
handle. ATS functionality is disabled
when in Hand position.
• Lock-position = Locking mode, padlock-
ing the automatic transfer switch in a
specific position to prevent automatic
and manual operation.
Notice
The handle has to be in its stored position
(not in use), after which the slide switch will
move to the Locking mode automatically and
the switch is allowed to be padlocked. To set
the operating handle back to its place, refer to
the left most picture in Fig. 3.6.
• AUTO-position = Automatic control
mode enabled, ATS is operable in Auto-
matic mode or from the HMI manual
control keys. When the slide switch is
moved to the AUTO position, the ATS is
functioning immediately in the auto-
matic control mode.

At the top of ZTS 30-1200 A, 200-480 Vac ATS, there is a set of LEDs intended to
model the state of the transfer switch sources, position, alarms, and mode.
A considerable amount of information can be deciphered from the LED states.
See the tables below for more information.
