SPECIFYING INFORMATION<br />
Installation notes<br />
When Designing, Specifying and Installing a <strong>Helvar</strong> lighting control system always refer to latest technical information<br />
(Installation guides, User and configuration manuals) found from the product packagings and online from www.helvar.com.<br />
Cable Requirements<br />
• DALI connections of up to 300 m can be made with any 2 wire 0.5 - 1.5 mm 2 mains rated cable<br />
• The DIGIDIM panels must be earthed as shown in the installation instructions<br />
• In rare instances where the environment may be electrically noisy, due to adjacent circuits carrying high switching currents,<br />
we recommend a 2 wire twisted pair screened and sheathed cable.<br />
• DALI cable must be mains-rated and the maximum voltage drop along the length of the cable must not exceed 2V.<br />
