4 This product is to be installed only in a Restricted Access Location
(dedicated equipment rooms, equipment closets or the like) in accordance
with articles 110-16, 110-17 and 110-18 of the National Electrical Code,
ANSI/NFPA 70.
5 This product is to be connected to a 48 VDC SELV supply source that is
electrically isolated from the AC source.
6 The positive terminal of the 48 VDC source is to be reliably connected to
earth. Connect a green/yellow earthing (grounding) wire to the protective
earthing (grounding) lug connector, identified by the protective earth
symbol on the chassis.
7 A readily accessible disconnect device as part of the building installation
shall be incorporated in fixed wiring. The disconnect device (a 48 VDC,
30 A, single pole circuit breaker or switch) must be included in the
ungrounded supply conductor. Over current protection must be included
with a 48 VDC, 30 A fuse or circuit breaker in the ungrounded conductor.
Use minimum 8 AWG (6 mm
2
) fixed power source wires with strain
retention.
8 Do not allow anything to rest on the power cord and do not locate the
product where persons will walk on the power cord.
9 Slots and openings in the cabinet are provided for ventilation. To ensure
reliable operation of the product and to protect it from overheating, these
slots and openings must not be blocked or covered.
10 General purpose cables are described for use with this product. Special
cables, which may be required by the regulatory inspection authority for
the installation site, are the responsibility of the customer. To reduce the
risk of fire, use a UL Listed or CSA Certified, minimum 26 AWG (0.128
mm
2
) telecommunication cable, or comparable cables certified for use in
the country of installation.
11 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 products.
12 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 a telephone (other than a cordless type) during an
electrical storm. There may be a remote risk of electric shock from
lightning.
