3.
Line Cords
- Equipment that has a removable telecommunications line cord is to
be connected to the test circuit with a line cord having 0.4mm (26 AWG) or
larger copper wire conductors and not more than 1
total resistance.
4.
Functional Circuitry
- UL mandates that functional circuitry must be used for
each over-voltage test conducted. This allows damaged circuitry to be repaired
or replaced before subsequent testing. Alternatively, separate samples may be
used for each test.
5.
Wiring Simulators
- A wiring simulator is used to indicate whether the maximum
I
2
t imposed upon telecommunications wiring has been exceeded. For Tests 1 &
5, a wiring simulator is to be used unless the equipment is specified for use with
a suitable secondary protector or a secondary protector simulator. The wiring
simulator can consist of one of the following:
a. A 50mm length of .2mm (32 AWG) bare or enameled solid copper wire
(for Test condition 1).
b. A Bussman Mfg. Co. Type MDL-2A fuse (for Test condition 1).
c. A 300mm length of .4mm (no. 26 AWG) solid copper wire which connects
to a representative installation (includes wiring an connectors). This option
is used when the manufacturer specifies the complete installation from the
network interface to the equipment.
d. Current probe used with a 300mm length of .5mm (24 AWG) copper wire
(for Test condition 1).
Note:
Test conditions 2, 3, & 4 do not require the use of a wiring simulator or a secondary
protector simulator. Any secondary protection simulators used in Tests 1 & 5 should be
similar to the test fuse used in UL 497A, Standard for Secondary Protectors for
Communications Circuits.
Over-Voltage Test Compliance
Equipment is deemed compliant if both of the following conditions are met during test:
1. An absence of ignition or charring of the cheesecloth indicator (charring is
deemed to have occurred when the threads have been reduced to char by a
glowing or flaming condition).
2. The wiring simulator (Figures 4-12 & 4-13) does not open during the appropriate
test, or for test condition 1 (Table 4-18), the integral I
2
t measured with a current
probe is less than 100A
2
s.
After completion of the Over-Voltage Tests, equipment must comply with either the
Dielectric Voltage-Withstand Test requirements or Leakage Current Test requirements
listed in sections 6.3 and 6.4 of UL 1950.
Special Considerations Regarding the SIDACtor and UL 1950.
SIDACtors are recognized under UL 497B
SIDACtor epoxy used is UL recognized and the encapsulated body passes
UL 94V-0 requirements for flammability.
The only specific requirements of UL 1950 that pertains to the SIDACtor itself is the
mandate that components be UL listed. All other UL 1950 requirements pertain to
the equipment being evaluated.
