Instructions for ATS bypass switches

Test certificate number:

Signature:

The installer is responsible for ensuring that the installation conforms to the requirements of BS 7671 (Wiring regulations) and best safe working practice.

Prior to installation ensure you have the correct device to meet withyour requirements.Please visit www.switchgear-systems.com for more information.

These ATS bypass switches are compatible with our entire range of ATS panels and are designed to comply with the legislation for bypass of life safety systems included in BS9999 & BS8519:2010.

We offer both single and dual line bypass solutions to accomodate the requirements of the installation. When ordered alongside an ATS panel we willcombine and test them in house but are also conveniently labeled for retro fitting on site.

This unit adheres to European standard IEC60947-6-1 for changeover equipment. This units is fully mains tested prior to leaving Switchgear Systems Ltd.

OVERVIEW

SPECIALREQUIREMENT?JUST ASK!

Single line ATS bypass

• Integrated bypass and ATS panels suitable for life safety applications.

• Total isolation of the ATS panel from load and sources for maintainance

purposes.

• In bypass position the primary supply is linked direct to load.

• Normally open auxiliary for isolation of GenSet start signals.

When ordered alongside out ATS panels Switchgear

Systems Ltd will mechanically and electronically fit the

ATS bypass to the bottom of the ATS panel.

Alternative layouts are available upon request.

Dual line ATS bypass

• Integrated bypass and ATS panels suitable for life safety applications.

• Total isolation of the ATS panel from load and sources for maintainance

purposes.

• In bypass position you can select primary or auxiliary supply to be linked

to load via the selector switch.

• Normally open auxiliary for isolation of GenSet start signals.

OVERVIEW

Installation Instructions

1. Before beginning the installation please ensure you have ordered the correct type of bypass switch for your application. When purchased with an integrated ATS panel you should also check and confirm that the type and rating of the ATS panel is correct. b

2. If the ATS includes a generator start signal you should wire it through the N/O contact built into the bypass switch. This will prevent the generator from starting up when the unit is switched into bypass mode. b3. The enclosure comes with 4 pre-drilled holes in the back for mounting; please see opposite page for dimension details for drilling. Alternatively, wall mounting brackets are also available to order.b

4. Please refer to the cable installation instructions (pages 09, 13, 17 or 21 depending on the model you have) for details showing which terminals to connect your cables to.b

5. Cables should be installed by a qualified electrician. Gland and make off cables to appropriate lengths, being sure to adhere to the requirements set in BS7671.b

6. Terminate and connect cables with appropriate ferrules and lugs where necessary. Torque settings are shown in the table on the opposite page. Please see the Connection Diagram (pages 09, 13, 17 or 21 depending on the model you have) for details on where to terminate your cables.

Please note: Before commissioning ensure all terminals are tightened, including those factory fitted, as these may loosen during transit and storage. Maintenance of the IP ingress protection is the responsibility of the installer. All Panels are mains tested before leaving Switchgear Systems Ltd.

Single Line Installation Instructions (40-125A)

When factory fitted:

• Connect your incoming cables from the primary supply to the terminals

marked ‘Primary Supply Input’.

• Connect your incoming cables from the auxiliary supply to the terminals

marked ‘Auxiliary Supply Input’.

• Connect your outgoing supply cables to the load/distribution network to

the terminals marked ‘Outgoing Supply’.

When supplied alone:

• Follow the instructions above.

• Join the ‘Primary Supply Input’ terminals on the ATS to the ‘Primary

Output To ATS’ terminals in the bypass switch.

• Join the ‘Auxiliary Supply Input’ terminals on the ATS to the ‘Auxiliary


• The ‘Outgoing Supply’ terminals of the ATS should then be joined to the

terminals in the bypass switch marked ‘Input From ATS’.
