7 ELECTRIC INSTALLATION
Strictly observe the electrical input values indicated on the rating plate.
Install the Q-2Rils 485 alarms control unit on a dry surface in a non-oxidising, non-corrosive and vibration-free
atmosphere. If installed outdoors, the panel must be as protected from direct light as much as possible; take
all necessary precautions to keep the external temperature within the limits of use indicated in section 6.
Elevated temperatures accelerate the ageing of all components and lead to more or less serious malfunctions.
Make sure the fitter installs the lines correctly.
Before connecting the power cables to terminals L1 - N - PE of the terminal board, make sure that the general
switch on the power distribution board is turned to OFF (O) and that no-one can accidentally turn it on again.
Scrupulously observe all current safety and accident prevention regulations.
Make sure that all the terminals are fully tightened.
Make sure the connection cables are in perfect condition and that the external sheathing is intact.
ATTENTION! The customer must install a 30 mA differential switch protecting the Q-2Rils 485 control unit.
The system must be correctly and safely earthed according to current regulations.
Instrumental tests to be performed by the fitter:
a) Continuity of the protection conductors and of the main and supplementary equipotential circuits.
b) Insulation resistance of the electrical system.
c) Differential protection test.
d) Applied voltage test.
e) Operating test.
