EST3 System Operation Manual vii
Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any
repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications
company cause to request the user disconnect the equipment.
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
Note: 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 requirements that the
sum of the Load Numbers of all the devices does not exceed
100.
