General information

General Information

About the Installation Manual

This publication is intended as a guide for the installation of the MCC (Marine Commercial Control). The publication is not comprehensive and does not cover every possible installation, but is to be regarded as recommendations and guidelines applying to Volvo Penta standards.

IMPORTANT! Installation of electrical systems shall only be carried out by a professional marine electrician.

IMPORTANT! Before attempting to install the

MCU to its power supply or other external devices, always refer to General Arrangement

Drawing for detailed information concerning installation. When in doubt, contact Volvo Penta.

The recommendations in this manual are the result of many years practical experience of installations all over the world. Departures from recommended procedures etc. can however be necessary or desirable, in which case the Volvo Penta organisation will be glad to offer assistance in finding a solution for your particular installation.

Installation manual for skilled professionals

This Installation Manual has been published for professionals and qualified personnel. It is therefore assumed that persons using this book have sufficient knowledge of marine drive and monitoring systems and are able to carry out related mechanical and electrical work.

It is the sole responsibility of the installer to ensure that the installation work is carried out in a satisfactory manner, that it is operationally in good order, that the approved materials and accessories are used and that the installation meets all applicable rules and regulations.

Only parts delivered or approved by Volvo Penta

Only components, cables, connections etc, delivered or approved by the manufacturer may be used. The manufacturer will take no responsibility what so ever if this requirement is violated.

Updates in Service Bulletins

Volvo Penta continuously upgrades its products and reserves the right to make changes. All the information contained in this manual is based on product data available at the time of going to print. Notification of any important modifications to the product causing changes to installation methods after this date will be made in Service Bulletins.

Installation

Great care must be taken in the installation of engines and their components. Always make absolutely sure that the correct specifications, drawings and any other data are available before starting work.

Plan installations with care

The installation must be planned very thoroughly and done with the greatest care. Plan the installation so that it is easy to carry out routine service operations involving the replacement of components (compare the Service Manual with the original drawings showing the dimensions).

IMPORTANT! Maximum permissible length of cable from engine to panel, is 40 m [130 ft].

The connection cable between the engine and the instrument panel must be securely clamped. Remember that the connectors must also be supported so that they are not subjected to any tension. Cables must not be run too close to hot components on the engine or close to any other source of heat. Make sure that it is protected from mechanical wear, sharp edges and water splashes. If necessary, run the cable through protective conduits.

IMPORTANT! Cables must also be run on a safe distance from equipment that may disturb communication signals, i.e. radio transmitters or high current equipment.

Avoid making joints in the system as far as possible.

Cables and any joints must be accessible for inspection and service

NOTE! The connectors must be installed “dry”, they must not be packed with Vaseline etc.

General information

Joint liability

Each engine consists of many components working together. One component deviating from its technical specification can cause a dramatic increase in the environmental impact of an engine. It is therefore vital that systems that can be adjusted are adjusted properly and that Volvo Penta Genuine Parts as used.

Certain systems (components in the fuel system for example) may require special expertise and special testing equipment. Some components are sealed at the factory for environmental reasons. No work should be carried out on sealed components except by authorised personnel.

Environment

Remember that most chemical products damage the environment if used incorrectly. Volvo Penta recommends the use of biodegradable degreasing agents for cleaning engine components, unless otherwise indicated. Take special care when working on board boats to ensure that oil and waste are taken for destruction and not accidentally pumped into the environment with bilgewater.

Certified engines

The manufacturer of engines certified for national and local environmental legislation pledges that this legislation is met by both new and currently operational engines. The product must compare with the example approved for certification purposes. So that Volvo Penta, as a manufacturer, can pledge that currently operational engines meet environmental regulations, the following must be observed during installation:

• Service of fuel pumps, pump settings and injectors must always be carried out by an authorised Volvo Penta workshop.

• The engine must not be modified in any way except with accessories and service kits developed for it by

Volvo Penta.

• Installation of exhaust pipes and air intake ducts for the engine compartment must be carefully planned as its design may affect exhaust emissions.

• Seals may only be broken by authorised personnel.

IMPORTANT! Use only Volvo Penta Genuine Parts. Otherwise AB Volvo Penta will no longer take

responsibility for the engine meeting the certified design. All damage and costs caused by the use of non-genuine replacement parts will not be covered by Volvo Penta.

Safety information

Safety Information

Introduction

Read this Installation Manual carefully before installation. Improper installation may result in personal injury or damage to property or the engine itself.

If you do not understand or are uncertain about any operation or information in this Installation Manual, please contact Volvo Penta organisation.

Installation

This Installation Manual is produced for professional use only and must be used in conjunction with the relevant Operator’s Manual.

Volvo Penta will not assume any liability whatsoever for damage to materials or personal injury, which may result if the installation instructions are not followed or if the work is carried out by non-professional personnel.

The installer is responsible for ensuring that the system operates in accordance with this Installation Manual.

Work Procedures

Refer to the specific Operator’s Manual for relevant information where necessary, especially regarding safety and engine operation.

The work must be performed at Volvo Penta’s service workshops, boat builders or other authorized and suitably equipped workshops with personnel who have appropriate qualifications and experience.

Important!

The following special warning symbols are found in this manual and on the engine.

WARNING! Possible danger of personal injury, damage to property or mechanical malfunction if the instructions are not followed.

IMPORTANT! Used to draw your attention to something that can cause damage to or malfunction of a product or damage to property.

NOTE! Used to draw your attention to important information that will facilitate the work or operation in progress.

Safety directions for maintenance and service

WARNING! Installation, maintenance and service must be carried out with the engine stationary unless stated otherwise in the instructions. Prevent inadvertent start of the engine by turning off the power with the main switch, locking it in the off position. Disconnect primary and secondary power supply (positive(+) and negative(–) leads) and disable auxiliary starters. Place warning signs stating that work is in progress in every position from which the engine can be started.

Below is a summary of the risks you must observe and the safety precautions you must carry out when installing and co nfiguring the Control System.

Before carrying out electric arc welding, these measures of precaution should be at taken.

1.

Disconnect primary and secondary power supply

(positive(+) and negative(–) leads).

2.

Remove the connector from the engine control unit. Press in the lock tab (1), move the locking brace (2) up and pull the connector (3) out. Refit the connector to the engine control unit after disconnecting the welding equipment.

3.

Disconnect fuses in the electrical connection box on the engine.

4.

Disconnect the 8-pole connector positioned below the auxiliary stop-button.

Safety information

Take care to avoid all moving parts of the engine during testing and operation. Approaching an engine which is operating is a hazard to personal safety. Loose clothing or long hair can become entangled in moving parts, and may cause serious personal injury.

Never carry out work on an engine that is suspended from a hoist.

Only start the engine in a well-ventilated area. If operating the engine in a closed area ensure that there is exhaust ventilation leading out of the work area to remove exhaust gases and crankcase ventilation emissions.

The engine must not be run in areas where there are explosive materials or gases.

Never allow an open flame or electric sparks near the batteries. Never smoke in proximity to the batteries. The batteries give off hydrogen gas during charging, which when mixed with air can form an explosive mixture. This gas is easily ignited and highly flammable. Incorrect connection of the battery can cause a single spark, which is sufficient to cause a gas explosion. Do not alter the battery connections when attempting to start the engine (spark risk) and do not lean over any of the batteries. Refer to instructions in the Engine Instruction Manual.

Always ensure that the + (positive) and –

(negative) battery leads are correctly installed on their corresponding terminal posts on the batteries. Incorrect installation can result in serious damage to the electrical equipment.

Refer to the wiring diagrams in the Engine

Instruction Manual.

Always use protective eyewear when charging or handling the engine batteries. The battery electrolyte fluid contains sulphuric acid which is highly corrosive. If the battery electrolyte fluid comes into contact with unprotected skin, wash off immediately using copious amounts of clean water and soap, then seek medical assistance. If the electrolyte fluid comes in contact with the eyes, flush the eyes immediately (preferable using an eye bath) with copious amounts of clean water, and obtain medical assistance without delay.

IMPORTANT! AB Volvo Penta has developed and tested the complete system and its components. Non-original Volvo Penta components or components installed in a way that differ from the instructions may cause malfunction of the system.

IMPORTANT! Use only Genuine Volvo Penta

Spare Parts.

Use of non-original AB Volvo Penta spare parts will result in AB Volvo Penta being unable to assume liability for the engine meeting engine certification requirements. Any type of damage resulting from the use of non-original Volvo

Penta replacement parts for the roduct will not be covered under any warranty provided by AB

Volvo Penta.
