INSTALLATION - SAFETY CAUTIONS
WARNING: Marelli Motori recommends the initial start-up of a plant with MEC-100 regulation unit is carried
out by Marelli Motori Services and/or skilled personnel, strictly in accordance with the provided connection
diagrams. Any amendments to such diagrams must be either made or approved by Marelli Motori. Marelli
Motori is under no liability for any damages which may occur to the AVR, the plant or the persons, or for
lost earnings, or financial loss, or system stoppages, due to diagrams' modifications not previously
approved by Marelli Motori itself.
WARNING: DO NOT TOUCH THE REGULATOR BOARD WHEN IT IS POWERED.
When the regulator board is powered (that is, when the machine is running) the upper section of the device
(connection side) and all the parts electrically connected to it are subject to a voltage that can be lethal to
human beings. The board also includes components that during normal operation may reach high
temperatures, which are dangerous to human beings in case of direct contact.
Any operation on the wiring and/or any mechanical installation of the regulator must be performed by
qualified and informed personnel, with the generator stopped and after waiting for the regulator
components to reach a temperature that poses no danger to people safety.
Marelli Motori accepts no liability for any damages to the regulator, to the installations or to people, or for any loss of
earnings/money, or for any downtime due to failure to comply with the safety and/or installation/operating instructions contained
in this Technical Note.
