Sofrel S4W – Installation

Warning:

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1)

this device may not cause harmful interference,

and

(2)

this device must accept any interference received, including interference that may cause undesired operation.

The S4W contains a 2G/3G module certified under FCC ID: N7NHL8548.

This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment

should be installed and operated with a minimum distance of 20cm between the radiator and any part of your body.

This device was tested and found to comply with the limits of Class A digital devices, pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful interference when the device is used in a

commercial environment. This device generates, uses and can emit radiofrequency energy and, if not installed and used

following the instruction manual, can cause harmful interference to radio communications. Operating this device in a

residential zone is likely to cause harmful interference, in which case the user will be held responsible for correcting the

interference at his/her own expense.

Any modification made to this device that has not been explicitly approved by LACROIX Sofrel may cause harmful interference

and voids the FCC authorisation to use this device.

It is strictly forbidden to reproduce all or part of this manual or to distribute it in any form whatsoever, without the prior authorisation

of LACROIX Sofrel. The information contained in this manual has been carefully checked and is deemed to be correct. However,

LACROIX Sofrel cannot be held responsible for any errors or inaccuracies that may exist in this manual, nor for any resulting direct

or indirect damage, even if it has been informed of the possibility of such damage. Due to ongoing product development, LACROIX

Sofrel reserves the right to make any modifications to this manual and to related products at any time, with no prior notification to

concerned individuals.

Case - Features Case - Features Description • S4W comes standard in a compact case and includes the following: • DC power supply: • 1 24 V DC Power supply block (with backup battery) • I/O: • Input/output terminals for connecting: 16 DI, 4 AI (4-20 mA) and 4 DO •...
Page 3: Case - Mounting
Case - Mounting Case - Mounting The SCADA Central Station must be installed by qualified personnel in accordance with local regulations (NF C 15-100 in France, NEC in the U.S., etc.) The case must be installed in a fire-resistant enclosure. This enclosure must stay closed during normal operation; it is only accessible by qualified personnel and requires a key or tool to open it.

Page 7: Connection Of Dos
Case - Inputs/Outputs Connection of DOs DOs are 12 V / 24 V AC/DC ’very low voltage’ voltage-relay type digital outputs: they are compatible with 24 V relays and control panel indicator lights. By default, and following a total power cut (24V and Battery), DOs are in their 'open' state (idle state = 0). In case of product reinitialisation, the state of each DO is retained (no forced return to the idle state).
