Protective earth (PE) (main ground) connection is essential to safe operation and must
be verified before you connect to the power supply source and telecommunications
network. Do not defeat the purpose of the grounding-type plug by modifying it or using
an adapter. 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, do not proceed
with the installation until a qualified electrician has corrected the problem.
If the power supply is fed from a power source with no protective earthing path,
connect an earth-grounded copper wire of the proper size to the dedicated wiring
terminal marked with the protective earth (PE) symbol on the product chassis. See the
“Safety-Related Electrical, Physical and Environmental Information” appendix in
your hardware installation guide for the minimum wire size required for your product.
Models with AC power inputs are intended for use with a single phase three wire
power cord which includes an earthing conductor.
For models with DC power inputs, the protective earth (PE) connection must be
established by the dedicated earthing terminal marked with the PE symbol or, if
provided, by the earthing pin on the input terminal block.
10
Ensure that models with DC power inputs are connected to a -48V DC supply source
that is electrically isolated from the AC source in compliance with the standard and
local jurisdiction authorities of the country where you are installing the product:
UL1950 / UL 60950 in the United States
C22.2 No. 950 / No. 60950 in Canada
EN / IEC60950 in the European Union, Australia, New Zealand and Japan
11
For permanently connected equipment, the -48V DC power source must include a
double pole circuit breaker to provide a method of disconnecting the product from
power as required by national and international safety standards, and the local
jurisdiction authorities.
12
Before installing wires to the DC power terminal block, verify that these wires are not
connected to any power source. Installing live wires — wires connected to a power
source — is hazardous.
13
Do not allow anything to rest on the power cord, and do not locate the product where
people will walk on the power cord.
14
Do not attempt to service this product yourself. Opening or removing covers can
expose you to dangerous high voltage points or other risks, and may void the warranty.
Refer all servicing to qualified service personnel.
15
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.
