3 - Power supply
Introduction
E-kit must be supplied at 24 V D.C. E-kit connects to the power supply by means of a removable 5-pin
terminal box. Thanks to replication of pins L+/M, E-kit can, for example, supply external sensors (up to 8 A
max with 1.5 mm
2
conductors).
Alerts
WARNING!
Risk of damaging CPU and base of terminals!
Exceeding the maximum voltage value could cause irreparable damage to the system.
The system could be destroyed.
WARNING!
Risk of faulty operation!
To ensure reliable and correct operation, the supply voltage must increase from 0 to 24 V within
2.5 s maximum.
WARNING!
Risk of damage to base of terminal and power supply!
Short-circuits could damage the base of the terminal and power supply.
Make sure that the four L+ and M terminals (two of each) have not been connected in the wrong
way (e.g. +/- the power supplier is connected to both L+/L+ or both M/M terminals).
WARNING!
Risk of damage to base of terminal!
A high current could damage the terminal and base of the terminal.
Make sure that the current which flows through the removable terminals is never higher than 8 A
(with 1.5 mm of conductor).
