Who should use this manual?
The manual is intended for personnel such as operators of process monitoring/control
systems using a VM600 machinery protection system (MPS).
Operators are assumed to have the necessary technical training in electronics and
mechanical engineering (professional certificate/diploma, or equivalent) to enable them to
install, configure and use the system.
Applicability of the manual
The manual applies to a VM600 machinery protection system (MPS) using the new
generation of VM600 MPC4 cards (hardware versions 03x, 11x, 21x and subsequent
models). These later cards are easily distinguished from earlier models as they have seven
LEDs on their panels, whereas previous versions (01x and 02x) had only one LED (identified
as DIAG).
Users of systems having earlier versions of the MPC4 card should refer to edition 4 of this
manual.

Terminology
MPC4 cards
NOTE: The MPC4 machinery protection card is available in different versions, including a
standard version, a separate circuits version and a safety (SIL) version.
See 4 MPC4 / IOC4T card pair for additional information.
In general, MPC4 is used in this manual to refer to all versions of the card. However, where
it is necessary to make a distinction, MPC4 is used to indicate the standard and separate
circuits versions of the card and MPC4SIL is used to indicate the safety version.

Important remarks on safety
Every effort has been made to include specific safety-related procedures in this manual using
the symbols described above. However, operating personnel are expected to follow all
generally accepted safety procedures.
All personnel who are liable to operate the equipment described in this manual should be
trained in the correct safety procedures.
Meggitt does not accept any liability for injury or material damage caused by failure to obey
any safety-related instructions or due to any modification, transformation or repair carried out
on the equipment without written permission from Meggitt SA. Any modification,
transformation or repair carried out on the equipment without written permission from
Meggitt SA will invalidate any warranty.
Electrical safety and installation
FAILURE TO FOLLOW THE INSTRUCTIONS AND IMPLEMENT THE RECOMMENDATIONS IN
THIS MANUAL MIGHT RESULT IN INJURY TO THE OPERATOR AND/OR THIRD PARTIES,
AND/OR RESULT IN DAMAGE TO EQUIPMENT AND WILL INVALIDATE ANY WARRANTY.
Read this manual carefully and observe the safety instructions before
installing and using the equipment described.
By doing this, you will be aware of the potential hazards and be able to work
safely, ensuring your own protection and also that of the equipment.
WHEN INSTALLING A VM600 RACK, OBSERVE ALL SAFETY (WARNING AND CAUTION)
STATEMENTS IN THIS MANUAL AND FOLLOW ALL NATIONAL AND LOCAL ELECTRICAL
CODES.
ONLY TRAINED AND QUALIFIED PERSONNEL (SUCH AS A QUALIFIED/LICENSED
ELECTRICIAN) SHOULD BE ALLOWED TO INSTALL OR REPLACE THIS EQUIPMENT.
CHECK NATIONAL AND LOCAL ELECTRICAL CODES, REGULATIONS AND DIRECTIVES
BEFORE WIRING.
A VM600 RACK MUST BE DIRECTLY AND PERMANENTLY CONNECTED TO PROTECTIVE
EARTH (PE), KNOWN AS AN EQUIPMENT GROUNDING CONDUCTOR IN THE US
NATIONAL ELECTRICAL CODE, USING THE EARTH CONDUCTOR OF THE EXTERNAL
MAINS POWER SUPPLY LEAD (POWER CORD), IN ORDER TO HELP PREVENT THE RISK
OF ELECTRIC SHOCK.
SELECT CABLE WIRE SIZES AND CONNECTORS (CURRENT-CARRYING CAPACITY),
INCLUDING THE EXTERNAL MAINS POWER SUPPLY LEAD (POWER CORD), TO MEET THE
REQUIREMENTS OF THE APPLICATION IN ACCORDANCE WITH THE APPLICABLE
NATIONAL AND LOCAL ELECTRICAL CODES.
CHECKS TO ENSURE ELECTRICAL SAFETY SHOULD BE CARRIED OUT BY A COMPETENT
PERSON.
DEFLECTION PLATES (BARRIERS) MUST BE INSTALLED ABOVE AND BELOW A VM600
RACK IN ORDER TO HELP REDUCE THE RISK OF ELECTRICAL SHOCK AND IN THE CASE
OF THE BARRIER INSTALLED BELOW A VM600, IN ORDER TO HELP PREVENT THE
SPREAD OF FIRE TOO.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN DEATH, SERIOUS INJURY,
AND/OR EQUIPMENT DAMAGE.
SEE 8INSTALLATION FOR FURTHER INFORMATION.

Hazardous voltages and the risk of electric shock
Hot surfaces and the risk of burning
Heavy objects and the risk of injury
HAZARDOUS VOLTAGES EXIST WITHIN A VM600 RACK.
WHEN A CARD, PANEL OR POWER SUPPLY IS REMOVED FROM A VM600 RACK, THE
RACK BACKPLANE – CONTAINING HAZARDOUS VOLTAGES – IS EXPOSED AND THERE
IS THE RISK OF ELECTRIC SHOCK, AS INDICATED BY THE USE OF THE FOLLOWING
WARNING LABEL ON THE EQUIPMENT:
REGARD ANY EXPOSED COMPONENT, CONNECTOR OR PRINTED CIRCUIT BOARD (PCB)
AS A POSSIBLE SHOCK HAZARD AND DO NOT TOUCH WHEN ENERGISED.
FOR SAFETY REASONS, ANY VM600 RACK SLOT (CARD POSITION)NOT POPULATED
BY A VM600 CARD MUST BE COVERED BY A BLANK PANEL.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN DEATH, SERIOUS INJURY,
AND/OR EQUIPMENT DAMAGE.
SEE 8INSTALLATION FOR FURTHER INFORMATION.
HOT SURFACES CAN EXIST WITHIN AND ON A VM600 RACK.
DEPENDING ON THE AMBIENT OPERATING TEMPERATURE AND POWER CONSUMPTION,
AND THE INSTALLATION AND COOLING OF A VM600 RACK, THE TOP OF THE RACK CAN
BECOME HOT TO TOUCH AND THERE IS THE RISK OF BURNING WHEN HANDLING THE
RACK, AS INDICATED BY THE USE OF THE FOLLOWING WARNING LABEL ON THE
EQUIPMENT:
REGARD THE TOP OF A VM600 RACK AS A HOT SURFACE AND DO NOT TOUCH
UNLESS COOL.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN INJURY.
A FULLY POPULATED VM600 SYSTEM RACK (ABE04X) WITH VM600 CARDS AND
RPS6U RACK POWER SUPPLIES INSTALLED IS A HEAVY OBJECT.
DEPENDING ON THE NUMBER OF CARDS AND RACK POWER SUPPLIES INSTALLED, A
VM600 SYSTEM RACK CAN BE TOO HEAVY TO HANDLE MANUALLY BY ONE PERSON
AND THERE IS THE RISK OF INJURY DURING INSTALLATION OR REMOVAL.
ACCORDINGLY, A FULLY POPULATED VM600 SYSTEM RACK SHOULD BE CONSIDERED
AS A HEAVY OBJECT THAT REQUIRES TWO PEOPLE TO LIFT, LOWER OR OTHERWISE
HANDLE MANUALLY.
ALTERNATIVELY, THE RPS6U RACK POWER SUPPLIES (THE HEAVIEST SYSTEM
COMPONENTS AND EASILY REMOVABLE), AND THEN VM600 CARDS AS NECESSARY,
CAN BE REMOVED FROM A VM600 SYSTEM RACK IN ORDER TO REDUCE THE WEIGHT
AND ALLOW ONE PERSON TO SAFELY HANDLE MANUALLY.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN INJURY.

Handling precautions for electrostatic sensitive devices
Certain devices used in electronic equipment can be damaged by electrostatic discharges
resulting from built-up static electricity. Because of this, special precautions must be taken to
minimise or eliminate the possibility of these electrostatic discharges occurring.
• Before handling electronic circuits, discharge the static electricity from your body by
touching and momentarily holding a grounded metal object (such as a pipe or cabinet).
• Avoid the build-up of static electricity on your body by not wearing synthetic clothing
material, as these tend to generate and store static electric charges. Cotton or cotton
blend materials are preferred because they do not store static electric charges.
• Do not handle electronic circuits unless it is absolutely necessary. Only hold cards by
their handles or panels.
• Do not touch printed circuit boards, their connectors or their components with conductive
devices or with your hands.
• Put the electronic circuit, printed circuit board or module containing electronic
components into an antistatic protective bag immediately after removing it from a VM600
rack.
Replacement parts and accessories
For information on replacement parts and accessories:
• Visit the Meggitt vibro-meter® Energy website at www.meggittsensing.com/energy
• Contact your local Meggitt representative.
Read the following recommendations carefully before handling electronic
circuits, printed circuit boards or modules containing electronic
components.
Use only approved replacement parts and accessories.
Do not connect with incompatible products or accessories.
Only use replacement parts and accessories intended for use with
VM600 racks that have been approved by Meggitt SA.
Using incompatible replacement parts and accessories could be
dangerous and may damage the equipment or result in injury.
