Electrical Connections; Table Of Parameters To Be Established In The Kl1 Control Unit, Dedicated To Ebara Technicians - EBARA 2SP EFC 1,5T-1 Instrucciones Para La Instalación Y El Mantenimiento

8.7 ELECTRICAL CONNECTIONS

8.7.1 Before connecting the power cables to terminals L1 - L2 - L3 on the insulating switch, ensure that the main switch
on the power distribution panel is in OFF position (O), and that no one can switch on the power accidentally.
8.7.2 Scrupulously observe all the regulations in force concerning safety and accident prevention.
8.7.3 Ensure that all the terminals are fully tightened, paying particular attention to the earth terminal.
8.7.4 Connect the cables to the terminal board as indicated in the wiring diagrams given in the enclosed booklet.
8.7.5 Check that all the connecting cables are in excellent condition, with the external sheathing unbroken.
8.7.6 ATTENTION ! In the system, install differential switches type:
Class A, with adjustable dispersion current: 300 mA, selective, protected
against sudden tripping, delay time 0.5 seconds.
Provide automatic protection of the supply line against short circuits by means of ACR fuses type
_gG" according to the following table:
8.7.7
The apparatus must be correctly and safely earthed as required by the
regulations in force.
8.7.8 Depending on the type of installation, limit the maximum length of the power .
8.7.9 Instrumental checks to be carried out by the installer:
a) continuity of the protection leads and of the main and supplementary equipotential circuits;
b) insulation resistance of the electric system;
c) test efficiency of the differential protection;
d) test the applied voltage;
e) test operation.
