1. General safety precautions

“Important instructions for installation safety.

Incorrect installation can cause serious injury”

This installation manual is intended for qualified personnel only.
Installation, electrical connections and adjustments must be performed in accordance
with Good Working Methods and in compliance with the present standards.
Read the instructions carefully before installing the product. Bad installation could
be dangerous.

The packaging materials (plastic, polystyrene, etc.) should not be discarded in

the environment or left within reach of children, as they are a potential source
of danger.
Before installing the product, make sure it is in perfect condition.
Do not install the product in explosive areas and atmospheres: the presence of inflam­mable gas or fumes represents a serious safety hazard.
The safety devices (photocells, safety edges, emergency stops, etc.) must be installed
taking into account: applicable laws and directives, Good Working Methods, instal­lation premises, system operating logic and the forces developed by the automation.

Before connecting the power supply, make sure the plate data correspond to that

of the mains power supply. An omnipolar disconnection switch with a contact
opening distance of at least 3mm must be fitted on the mains supply.
Check that there is an adequate residual current circuit breaker and a suitable overcur­rent cutout upstream of the electrical installation in accordance with Good Working
Methods and with the laws in force.
When requested, connect the automation to an effective earthing system that complies
with current safety standards.
During installation, maintenance and repair operations, cut off the power supply before
opening the cover to access the electrical parts.

The electronic parts must be handled using earthed antistatic conductive arms.

The manufacturer of the motorisation declines all responsibility if component
parts not compatible with safe and correct operation are fitted.
Only use original spare parts for repairing or replacing products.

4. Electrical connections

Before connecting the power supply, make sure the plate data correspond to that of the mains
power supply.
An omnipolar disconnection switch with a contact opening distance of at least 3mm must be
fitted on the mains supply.
Check there is an adequate residual current circuit breaker and overcurrent cutout upstream
of the electrical system.
For the mains power supply, use a H05RN-F 3G1.5 or H05RR-F 3G1.5 type electric cable. Con­nect it to terminals L (brown), N (blue), (yellow/green) inside the automation.
Secure the cable using a special cable clamp and remove the sheath only where the clamp is.
In the external automation section, the connections to the mains power supply and any other
low voltage wires (230V) must be made on an independent channel separated from the chan­nel of connections to the command and safety devices (SELV = Safety Extra Low Voltage), and
protected against overcurrents and short-circuiting. The channel must penetrate the automa­tion by a few centimetres through a Ø16 mm hole.
Make sure there are no sharp edges that may damage the power supply cable.
Make sure the mains power conductors (230 V) and accessory power conductors (24 V) are
separated.

4.1 Safety functions

The EL21 control panel has the following safety functions:

• force limitation;

• prevention of contact;

The maximum response time of the safety functions is 1.5 s. The reaction time to a faulty safety
function is 1.5 s.
The safety functions comply with the standard and performance level indicated below:

EN ISO 13849-1:2006 Category 2 PL=c

• emergency opening.

The maximum response time of the safety functions is 1.5 s. The reaction time to a faulty safety
function is 1.5 s.
The safety functions comply with the standard and performance level indicated below:

EN ISO 13849-1:2006 Category 2 PL=d

4.2 Electromagnetic emissions

WARNING: in accordance with Directive 2004/108/EC, the supplied ferrites must be
installed as shown on pages 24-25

Pass the cable through the ferrite, make 1 turn and protect it from knocks by using heat­shrink sheathing or similar.
The ferrite must be secured to the cable near the terminal boards (approx. 50 mm).
If you need to use several ferrites due to the number of cables involved, a special kit - KEMC2

- is available for this purpose.
