IMPORTANT SAFETY INSTRUCTIONS
Read and follow all warning notices and instructions marked on the product or included in this guide.
1. This product is intended to be used with a three-wire grounding type plug. This is a safety feature.
Equipment grounding is vital to ensure safe operation. Do not defeat the purpose of the grounding
type plug by modifying the plug or using an adapter.
2. Prior to installation use an outlet tester or a voltmeter to check the AC receptacle for the presence of
earth ground. If the receptacle is not properly grounded, the installation must not continue until a
qualified electrician has corrected the problem. In addition, a connection for earth or safety grounding
is provided on the chassis. It is a #6 threaded stud located next to the AC inlet receptacle.
3. Slots and openings in the ICX-250 are provided for ventilation. To ensure reliable operation of the
product and to protect if from overheating, these slots and openings must not be blocked or covered.
4.
DO NOT
allow anything to rest on the power cord and do not locate the product where persons could
step or walk on the power cord.
5.
DO NOT
attempt to service this product yourself, as opening or removing covers may expose you
to dangerous high voltage points or other risks. Refer all servicing to qualified service personnel.
6. Special cables, which may be required by the regulatory inspection authority for the installation site,
are the responsibility of the customer.
7. When installed in the final configuration, the product must comply with the applicable Safety Standards
and regulatory requirements of the country in which it is installed. If necessary, consult with the
appropriate regulatory agencies and inspection authorities to ensure compliance.
8. A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings.
If products installed in separate buildings are interconnected, the voltage potential may cause a
hazardous condition. Consult a qualified electrical consultant to determine whether or not this
phenomenon exists and, if necessary, implement corrective action prior to interconnecting the product.
INDUSTRY CANADA REQUIREMENTS
NOTICE:
The Canadian Industry Canada label identifies certified equipment. This certification
means that the equipment meets certain telecommunications network protective, operational and
safety requirements. The Department does not guarantee the equipment will operate to the user’s
satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the
facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. In some cases, the company’s inside wiring associated with a
single line individual service may be extended by means of a certified connector assembly (tele-
phone extension cord). The customer should be aware that compliance with the above conditions
may not prevent degradation of service in some situations.
Repairs to the 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 equip-
ment malfunctions, may give the telecommunications company cause to request the user to discon-
nect 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.
