MAX 4000 Series Hardware Installation Guide
12 Before installing wires to the MAX unit’s dc power terminal block, verify that these wires
are not connected to any power source. Installing live wires (that is, wires connected to a
power source) is hazardous.
13 If using dc power, connect the equipment to a 48 Vdc supply source that is electrically
isolated from the ac source. The 48 Vdc source should be reliably connected to earth
ground.
14 Install only in restricted-access areas in accordance with Articles 110-16, 110-17, and
110-18 of the National Electrical Code, ANSI/NFPA 70.
15 Do not allow anything to rest on the power cord, and do not locate the product where
persons will walk on the power cord.
16 Do not attempt to service this product yourself. Opening or removing covers can expose
you to dangerous high voltage points or other risks. Refer all servicing to qualified service
personnel.
17 General purpose cables are provided with this product. Special cables, which might be
required by the regulatory inspection authority for the installation site, are the
responsibility of the customer.
18 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.
19 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 might cause a hazardous condition. Consult a qualified electrical consultant to
determine whether or not this phenomenon exists and, if necessary, implement corrective
action before interconnecting the products.
In addition, if the equipment is to be used with telecommunications circuits, take the following
precautions:
•
Never install telephone wiring during a lightning storm.
•
Never install telephone jacks in wet locations unless the jack is specifically designed for
wet locations.
•
Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•
Use caution when installing or modifying telephone lines.
Avoid using equipment connected to telephone lines (other than a cordless telephone)
during an electrical storm. There is a remote risk of electric shock from lightning.
•
Do not use a telephone or other equipment connected to telephone lines to report a gas
leak in the vicinity of the leak.
