1. Pre-Installation Instructions, Notes
1.1 General Notes
It is strongly recommend that you read this manual carefully before proceeding with the
installation.
Important information is highlighted by the headings WARNING, CAUTION, or NOTE.
These words are defined as follows:
WARNING - Warnings are used to indicate instructions which, if not
followed correctly, will probably result in personal injury or
substantial damage to equipment.
CAUTION - Cautions are used to indicate instructions or information which, if
not observed, may result in some damage to equipment if care is not taken.
NOTE - Notes are used to indicate instructions or information which are
especially helpful in understanding and operating the equipment, and which
will usually speed up the installation process.
1.2 Important Precautions And Notes
The following general rules and safety precautions must be observed for safe and reliable
operation of your system.
WARNING: If you need to change the EPROM program chip on the
CPU board, make sure you read the instructions and know exactly
how to install the new chip. Plugging the EPROM chip in upside-down
may damage the chip. Static electricity can damage the EPROM, so
avoid touching the pins on the chip, and ground yourself (by touching
the controller cabinet) before touching the chip or the controller. Do
not expose the EPROM program chip to bright light, and do not
remove the label over the EPROM program chip window.
WARNING: The elevator controller must be installed by experienced
field installation personnel. The field installation personnel must
know and follow all the rules and regulations pertaining to the safe
installation and running of elevators. Additional information for
specific devices (such as the valves, door operator, etc.) is the
responsibility of the manufacturers of those devices.
WARNING: This equipment is designed and built to comply with ANSI
A17.1, ASME A17.5 and CAN/CSA B44.1 and must be installed by a
qualified contractor. It is the responsibility of the contractor to make
sure that the final installation complies with all applicable local, state
and national codes, and is installed safely.

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 7
WARNING: The 3 phase AC power supply to this equipment must
come from a fused disconnect switch or circuit breaker which is sized
in accordance with all applicable national, state and local electrical
codes, in order to provide the necessary branch circuit protection for
the controller and motor. Incorrect motor branch circuit protection
may create a hazardous condition.
WARNING: Proper grounding is vital for the safe operation of your
system. Bring the ground wire to the ground stud that is labeled
"GND" or "G". You must choose the proper conductor size. See
national electrical code article 250-95, or the related local applicable
code.
Pay special attention to points highlighted in this manner. They
are of special consideration and are frequently overlooked.

2. Controller Installation and Wiring
2.1 Controller Installation
2.1.1 Controller Location Selection and Environment
Mount the controller in a location that provides:
•adequate support for the weight of the controller,
•adequate lighting for installation and maintenance,
•convenient access for the routing of required conduits and cables,
•convenient access to other devices in the machine room,
•a minimum of vibration (supply additional bracing or reinforcement if required).
For improved controller reliability:
•Keep the machine room clean.
•Do not install the controller in a dusty area.
•Do not install the controller in a carpeted area, or area where static electricity is a
problem.
•Keep room temperature between 0C to 50C (32F to 122F), and 95% non-
condensing relative humidity. Extended high temperatures will shorten the life of
electronic components. Provide adequate ventilation or air-conditioning as required
if necessary.
•Avoid condensation on the equipment. Keep the controller away from sources of
condensation and water (such as open windows) as these can create a hazardous
condition and can damage the equipment.
•Do not install the controller in a hazardous location and where excessive amounts of
vapors or chemical fumes may be present. A NEMA 4 or NEMA 12 rated enclosure
can be provided if necessary.
•Make sure power line fluctuations are within 10%.
•High levels of radio frequency emissions may cause interference with the controller
microprocessor, and produce unexpected results. This could be caused by hand-held
communications devices used near the controller.
•Long term operation of the controller without the door or cover in place is not
recommended.
