Safety Precautions
Users should ensure for their own protection that the electrical ground connections of the
power utility, telephone lines and internal metallic water pipe system, if present, are
connected together. This precaution may be particularly important in rural areas.
CAUTION
Users should not attempt to make such connections themselves, but should
contact the appropriate electric inspection authority, or electrician, as appropriate.
DANGER
Les utilisateurs ne doivent pas essayer d'établir eux-mêmes de telles connexions,
mais doivent contacter l'électricien ou l'organisme de vérification électrique
appropriée, selon le cas.
The Load Number (LN) assigned to each terminal device denotes the percentage of the
total load to be connected to a telephone loop which is used by the device, to prevent
overloading. The termination on a loop may consist of any combination of devices subject
only to the requirement that the total of the Load Numbers of all the devices does not
exceed 100.
