PRODUCT OVERVIEW
Product ID: Zonit

Automatic Transfer Switch Industrial (Z-ATS-IND
™)
Model: Z-ATS-IND-XX-XXX (All models)
Description: The Z-ATS-IND™ is a small form factor, “zero-U” mounting, auto-ranging, automatic transfer switch for
(88-277VAC) service.
This product is designed for use with devices requiring high to ultra high power path reliability, with quick failover times
and is suitable for microprocessor controlled industrial devices. It has an extended operating voltage range and higher
temperature operating limits suitable for industrial and harsh environments.
PRODUCT FEATURES
 The Z-ATS-IND™ can be ordered with wire harness inputs & output, which is the base model. This is the most
convenient way to connect to terminal blocks, which are the most common power wiring connection in industrial
control cabinets. Corded connections are available as an option, using IEC standard or Zonit IEC locking power
cords. Other wire harness and cordcap options are available as custom configurations.
 The unit is designed for “zero-U” mounting in most applications. The “T”-slot features of the case are designed to
accept a 35mm “top-hat” style DIN rail. The most common DIN rail attachment method is to install a DIN rail adapter
(available from Zonit) to the case, using the “T-slots” and then affix the unit to the DIN rail. This allows the unit to be
placed on and removed from the DIN rail, for ease of installation and maintenance.
 The terminal block versions and the power input plugs in corded versions of the Zonit Z-ATS-IND™ are labeled so
that the user knows which is the A source and which is the B source. Further the input plugs can be color coded as
desired by the user to key the input plugs to any color-coding scheme used in their application to identify power
sources.
 The Zonit Z-ATS-IND™ is designed to always use the A source if it is available and of acceptable quality. This allows
electrical installers or designers to know and plan for the load on each power source - a requirement for power
capacity management.
 The unit has will illuminate a green LED when the A power source is in use. It will illuminate a blue LED when B power
source is in use. The blue LED will blink if the unit is on the A power source, but the B power source is present and
available.
 Under-voltage and over-voltage conditions are detected and will initiate a switch from the A to B source. This helps
protect against downtime and makes it easy to use line + UPS power sources without risking downtime.
 The Z-ATS-IND™ has voltage level sensing on the A side only and will switch to the B side if the A input voltage is
less than 88VAC or greater than 305VAC. Once the A side voltage goes back in range for at least 6 seconds, (either
greater than 88VAC or less than 305VAC), the unit will switch back to A side power.
 For applications that require a restricted operating voltage range, the Z-ATS-IND™ can be custom ordered in a
configuration that will switch from the A to the B source when the lower or upper limits of the voltage range are
exceeded. An example would be a 200-250V operating range. Note that units with custom operating voltage ranges
will have different transfer & return values from those specified in the bullet above.
 The Zonit Z-ATS-IND™ comes in a standard internally fused model that protects the unit from being permanently
damaged by overloads. The 10A model can optionally be equipped with two cigarette-style circuit breakers one
each for the A source and the B source. The unit will disconnect the attached load from the active service input,
(either the A or B source), if the current drawn by the load exceeds the amperage rating of the unit for a reasonable
duration of time. This will pop up the center plunger of the tripped circuit breaker. After removing the excessive
connected load, the Z-ATS-IND™ can then be reset by pressing the tripped circuit breaker center plunger back in. If
the circuit breaker has sufficiently cooled, the center plunger will stay in and the unit will supply power to the outlet.
If the circuit breaker plunger does not stay in, the circuit breaker has not sufficiently cooled off, wait and retry later.
Note that the circuit breakers can not be manually opened, they can only be tripped by an overload condition.

PRE-INSTALLATION CONSIDERATIONS
Prior to deployment of the Z-ATS-IND™, to insure the unit will function properly in its intended application, the following
site considerations should be reviewed.
POWER TYPE & MOUNTING OPTIONS
The Z-ATS-IND™ comes with either wire harness I/O cords or country or application specific input and output cords with
cordcaps. For example, IEC C14 normal or Zonit zLock
™
locking plugs could be used on both its A and B input cords,
which are to be connected to single phase 100-250VAC power sources. The output is most commonly an IEC320 C13
female normal or Zonit locking plug, which is a common input to many electronic devices.
The Z-ATS-IND™ can be used in several configurations:
 Direct Terminal Block Attach – The Z-ATS-IND™ is connected directly to equipment via its wiring harness cords..
 Indirect Terminal Block Attach – The Z-ATS-IND™ can be connected indirectly to equipment via a suitable
terminal block. The Z-ATS-IND wire harness is connected to the terminal block. Consult your local electrician to
insure compliance with all applicable safety standards.
 Direct Plug Feed – The Z-ATS-IND™ can be connected to electrical sockets via the supplied power cords on
corded models of the Z-ATS-IND™.
SITE PREPARATION
Site preparation with the Z-ATS-IND™ is simple and easy to implement.
The site must have two separate power sources with appropriate wiring for each power source that the Z-ATS-IND™ can
be connected to via suitable agency approved power wiring or receptacles. The Z-ATS-IND™ must be fed from both the A
and B sources by single phase 88-277VAC power of suitable capacity. Make sure that the A and B socket-outlets to be
used are installed near the equipment the Z-ATS-IND™ will power and are easily accessible. Also make sure that they
are identified for staff performing the Z-ATS-IND™ installation
Note! The maximum rated voltage of the Z-ATS-IND is dictated by the power cord endcap type, when corded I/O is used..
The maximum rated operating voltage of the endcaps is the maximum allowed voltage that is marked on the case. This is
the voltage limit that must be observed when installing and using the unit.
 The Z-ATS-IND™ should be wired or plugged in such that the A power source is the preferred source for normal
operations for the equipment being powered. The B power source is the failover power source. This point is
important, the Z-ATS-IND™ only monitors power quality when drawing on the A power source.
 Insure that the needed power capacity that will be drawn by the Z-ATS-IND™ is available in the both the A and B
circuits the Z-ATS-IND™ is connected to. This is necessary for the Z-ATS-IND™ to failover correctly and insure
connected load uptime.
INSTALLATION
 Remove the Z-ATS-IND™ from its packaging and verify that the unit is intact and undamaged and is the model
ordered for the desired application. The packaging should contain the Z-ATS-IND™ unit, and any optionally
ordered accessories.
 Connect the Z-ATS-IND™ main unit via the wiring harness or supplied output plug into the equipment to be
powered, directly or indirectly. If the locking plug on the Z-ATS-IND™ will not insert because of clearance issues,
use an optional accessory, the IEC C13 Extension Kit (Part Number: Z-ATS1-EXT-C13). This C13 extension cord
can be used to make the connection between the equipment and the Z-ATS-IND™. Do NOT yet connect either
the A or B input sources of the Z-ATS-IND™, that will be done at a later step.

 If it is desired or required to mount the Z-ATS-IND™ to a DIN rail, then insert the 35mm top-hat DIN rail into the
compatible provided case slots or use the optional µATS DIN Rail Adapter Kit (Part Number: Z-ATS-IND-DIN-
(1,2.3) and follow the included instructions to physically attach the Z-ATS-IND™ to the DIN rail.
 Check that the equipment is turned off if a power supply switch is on the equipment.
 Now connect the Z-ATS-IND™ to the A power source using either the wiring harness or the integral power cord.
The A power source should be shutdown when making this connection. Remember that the Z-ATS-IND™ will
always use the A power source when it is available. Then connect the Z-ATS-IND™ to the B power source using
either the wiring harness or the integral power cord. The B power source should be shutdown when making this
connection. Next activate the A , then the B input power sources. The Z-ATS-IND™ will turn on and the Z-ATS-
IND™ LED indicators will show that the unit is operational.
Note: If the connected load has no power switch it will turn on as soon as the A side Z-ATS-IND™power
source is connected.
 If the connected load has a power switch, turn it on.
DE-INSTALLATION
 Shutdown then power off all the equipment that the Z-ATS-IND™ is supplying power to. Be sure to follow the
manufacturers recommended shutdown procedure for all equipment. Shutdown both the A & B input power
sources to the Z-ATS-IND™ and insure they are inactive. If the unit has been physically secured, de-install the
retention kit. Disconnect the wiring harness connections to the unit or unplug the Z-ATS-IND™ input power cords,
in both models, first the B side, then the A side. Now remove the Z-ATS-IND™ from the installation location.
Note: If the connected load has no power switch it will turn off as soon as both the A & B input power sources to the Z-
ATS-IND™ unit are disconnected.
Z-ATS-IND™OPERATIONAL INDICATORS
The
Z-ATS-IND™ has 2 LED indicators, green and blue. They are used as follows to indicate the operational state of the
µATS™.

Green LED lit: The Z-ATS-IND™ is operating normally and drawing power from the A power source.

Blue LED lit: The Z-ATS-IND™ is operating normally and drawing power from the B power source. The primary source
is offline and not available or in an over-voltage or under-voltage condition.

Blue LED blinking: The Z-ATS-IND™ is operating normally and drawing power from the A power source. The B
secondary source is online and available for failover.
 No LEDs lit: The Z-ATS-IND™ is not receiving power from the A or B sources.
 No Output power but Green and/or Blue LEDs are lit: The Z-ATS-IND™ has been overloaded and blown one of its
protective fuses (very hard to do) or tripped its circuit breakers. Examine the A & B cigarette-style circuit breakers and
determine if either has tripped, if so, the central plunger in the circuit breaker will be sticking out. If yes, then remove the
overload from the Z-ATS-IND™ output and reset the tripped circuit breaker by pressing in the central plunger on the
circuit breaker. If it will not stay in, wait for a few minutes for the circuit breaker to cool and try again.
TROUBLESHOOTING
The Z-ATS-IND™ is designed and tested for the highest reliability possible. Factory testing is extensive, and all circuits
are fully tested for load capacity, isolation, circuit breaker trip limits, etc.
This unit contains no serviceable parts and must be returned to the manufacturer for repair or replacement.

If any condition exists that would indicate a problem, follow this process:
1) Check A and B source panel(s) (or PDU) circuit breakers. Be sure the A and B branch circuit breakers are fully
engaged. Snap them off and back on again. Now check the LED indicators at the µATS™.
2) Using a different
Z-ATS-IND™ unit
if available, can be useful in determining if the circuit is at fault, or if the Z-ATS-
IND™ is the source of the problem. If the same results are attained with two units, the problem is likely to be in the
branch feeder circuit.
3) If a problem is indicated on only one circuit feeding the
Z-ATS-IND™
, or at a particular receptacle on a plugstrip,
move the input plug(s) to the Z-ATS-IND™ to a different circuit or receptacles on a plugstrip that test OK.
4) The following tests should be done by a qualified electrician only. Using a suitable volt meter, test the A and B
power sources.
a) Verify Hot to Neutral or Hot to Hot on the A power input source is greater than 88V and less than 277V.
b) Verify phase to neutral voltages of 88 to 277 volts.
c) Verify 0.0 volts from Neutral to Ground.
d) Verify less than 1 ohm from Neutral to Ground.
5) If any fault is located with the branch feeder circuit, have a certified electrician correct it.
6) If the branch feeder circuit checks out as OK and a problem persists at the
Z-ATS-IND™
, return it to the factory.
