ZENER TECHNOLOGY AND QUALITY ASSURANCE
Since 1976 Zener Electric has supplied many thousands of drives to industry. These drives have been installed
into numerous applications resulting in a wealth of in house experience. The ZENER 8000-V AC variable speed
controller is the culmination of this experience, modern technology and industrial application requirements.
The Zener Quality Assurance program ensures that every ZENER 8000-V manufactured has proven to operate
correctly in the production test bay before dispatch.
SAFETY
Your ZENER 8000-V must be applied, installed and operated in a safe manner. It is the responsibility of the user
to ensure compliance with all regulations and practices covering the installation and wiring of your ZENER 8000-
V. The instruction manual should be completely read and understood before attempting to connect or operate
the ZENER 8000-V. Only skilled personnel should install this equipment. This equipment contains a number of
components that are designated by their various manufacturers as “not for use in life support appliances,
devices or systems where malfunction of the components can reasonably be expected to result in personal
injury or death”. Customers using or selling Zener products for use in such applications do so at their own risk
and agree to indemnify Zener for any damage resulting from improper use or sale.

ZENER 8000-V Installation Manual
IM00165 1
Explanation of symbols
WARNING
Indicates a condition or practice that, if the warning is not strictly observed,
could result in personal injury or death.
CAUTION
Indicates a condition or practice, if the caution is not strictly observed, could
lead to damage or destruction of equipment or a significant impairment of
proper operation.
WARNING
This symbol is used to highlight an electrical hazard. Failure to strictly observe
the warning could result in electrocution.
i
This symbol is used to highlight additional information on the product’s
capabilities or a common error in installation, commissioning or operation.
Warnings
Read all operating instructions before installing, wiring, operating, servicing or inspecting the
ZENER 8000-V.
Ensure that the instruction manual is made available to the final user of the product as well as
all personnel involved in any aspect of installation, adjustment or maintenance. Your ZENER
8000-V must be applied and installed by suitably qualified and experienced personnel in
accordance with this manual, good engineering practice and all local rules and regulations to
the end use environment.
There are hazardous voltages inside the ZENER 8000-V whenever it is connected to an electrical
supply and for some time afterwards.
Before touching anything inside the ZENER 8000-V enclosure or other equipment connected to
the ZENER 8000-V terminals, disconnect all sources of electrical power, wait at least 11 minutes
for capacitors within the ZENER 8000-V to discharge to less than 50VDC and then ensure, by
measurement, that there is no hazardous AC or DC voltage present at any terminal.
The ZENER 8000-V contains high energy circuits that may be hazardous. Do not operate ZENER
8000-V with the door open or any part of the enclosure removed.
Do not touch the terminals of the ZENER 8000-V or any associated motor and wiring when it is
energised, even if the ZENER 8000-V and motor are stopped. Electric shock may result.

ZENER 8000-V Installation Manual _
2 IM00165
Do not modify this equipment electrically, mechanically or otherwise. Modification may create
safety hazards.
The ZENER 8000-V is designed to drive an appropriately rated and otherwise suitable 3 phase
induction motor. It is not suitable for single phase motors or other types of motor or non-motor
load. Use with inappropriate load types may create a safety hazard.
Where the ZENER 8000-V is used as a component part of another product, it is the purchaser’s
responsibility to ensure that the final product meets all of the necessary safety, EMC,
regulatory, operational and other requirements for that product. Requirements for the
purchaser’s final product may be substantially different to the requirements for stand-alone
inverters.
The ZENER 8000-V is manufactured under strict quality control arrangements, however
additional and independent safety equipment must be installed if the application is such that
failure of the product may result in personal injury or property damage.
Ensure that electrical noise generated by the product and any associated equipment does not
adversely affect the proper operation of other equipment or systems, particularly those that
have a safety function.
Install emergency stop circuitry that removes power from the ZENER 8000-V and does not
depend on any feature of the product for proper and safe operation. Do not use the braking
functions of the product for safety purposes.
The ZENER 8000-V has features that may be used to cause an automatic restart in certain
circumstances. The overall application (machine etc) must be designed such that automatic
restart is not hazardous.
Do not install this equipment in locations where mechanical damage to the enclosure is
possible. In particular, consider vehicles, vandalism and attack by insects or animals. Severe
equipment damage and safety hazards may result.
Receiving
Inspect the ZENER 8000-V for any shipping damage. If any damage is found, report it to the carrier immediately.
Do not attempt to operate the ZENER 8000-V if any obvious damage exists.
After the initial inspection, the ZENER 8000-V can be repacked and stored in a clean, dry location until it is
required for use.
DO NOT store this equipment in an area where the ambient temperature will fall below -20°C or rise above
70°C. DO NOT store this equipment in areas that are subject to condensation or corrosive atmosphere. Proper
storage is necessary to ensure satisfactory controller start up and performance.
Software
This manual applies to ZENER 8000-V software revision 5.2.x. The software revision is displayed briefly at power
up and may also be viewed in the service menu.
i
This manual provides basic control configuration information for the ZENER 8000-V to suit
more common applications. Please refer to the ZENER 8000-V Reference Manual IM00140 for
a detailed explanation of each control feature, including communications protocols.

Installation
ZENER 8000-V mounting location
The ZENER 8000-V chassis is intended to be mounted in a switchboard style enclosure with the heatsink section
protruding through the rear wall of the enclosure. The input and output line reactors provided as part of the
ZENER 8000-V should be mounted within the switchboard, adjacent to, or on the enclosure floor, below the
ZENER 8000-V module chassis. The control console is separate to the ZENER 8000-V chassis and intended to be
mounted on the front of the switchboard enclosure for convenient operation. Mechanical protection may be
required to prevent damage to the heatsink section in some environments. The ZENER 8000-V portion within
the user’s switchboard enclosure is designed for use in a pollution degree 2
1
environment. The system
integrator and user are responsible for providing and maintaining this environment inside the switchboard
enclosure under all circumstances for the lifetime of the equipment.
Installation Information
CAUTION
The ZENER 8000-V must be mounted in a vibration free situation with heatsink fins
protruding through the wall of a switchboard type enclosure.
Do not mount the ZENER 8000-V where it is subject to heating by direct sunlight or
other heat radiating sources.
ZENER 8000-V must be mounted vertically. No other mounting orientation is
acceptable.
The thermal design of the user’s switchboard enclosure must be accommodate the
total heat dissipation of the ZENER 8000-V components together with the heat
dissipation any other equipment in the same enclosure and maintain the internal
ambient temperature within the range of 0 - 50°C without condensation.
Attention is drawn to the potential for condensation in vulnerable environments.
Additional precautions may be required for all enclosure types.
All of the parts associated with a drive system using parallel modules must be
installed in the same enclosure.
The installation location and environment should provide for safe access and
working conditions for maintenance personnel.
The mechanical design of the enclosure should provide for the safe removal and
replacement of drive modules and line reactors for maintenance purposes in a way
that suits the circumstances of the final installation site.
Do not drill holes in the ZENER 8000-V module enclosure except in the gland
plates.
Remove the module gland plate before drilling cable holes.
Do not allow metal shavings or any other conductive material to enter the
ZENER 8000-V module enclosure or line reactors. Serious damage may result.
