System planning and installation
Warning! Read ”Safety Information” starting on page 4 and observe all the safety precautions given
in this manual and in the manuals of the other devices in the system before planning or installing
the system. If you are in any doubt about system safety, or you plan to install VC-Dots™ in a
configuration that is not covered in this section, contact your Martin™ supplier for assistance.
Warning! Connect the VC-Dots™ system using only the devices and the cables specified in this
manual. Do not exceed the maximum numbers of devices that can be connected and the maximum
cable lengths specified in this manual and in the manuals of the other devices in the system. Note
that if you increase Dot pitch by inserting extra ribbon cable from Martin™ on a VC-Dot string, you
may have to remove Dots from the string in order to stay within safe limits.
Warning! Do not bend the VC-Dots ribbon cable into a curve of less than 26 mm (1 in.) radius.
Besides answering any questions that you might have about safety, your Martin™ supplier will be glad to
advise If you would like assistance creating a VC-Dots installation.
For ordering information for devices, cables and other accessories, see the specifications at the end of this
manual.

Important safety limits
Warning! To avoid the risk of fire or electrical faults, a VC Dots installation must respect safety limits
that ensure that cables and devices are not overloaded. Because the system is so flexible, you must
plan a system layout that stays within these limits before installing the system. Read the following
section carefully and do not exceed the limits given. If two different maximum limits apply to a
configuration, you must always respect the lower limit.
