Passes 1, 2, 3, 4, and 5 shown in Figure 4.5 refer respectively to Tests L1 and M1, L2 and

M2, L3 and M3, L4 and M4, and L5 shown in Table 4.17.

Equipment may be subject to the overvoltage tests shown in Table 4.17. The tests are

designed to simulate the following:

• Contact with primary power

• Short-term induction as a result of a primary power fault to a multi-earth neutral

• Long duration power fault to Ground

• Direct contact between the power mains and a telecommunications cable

Notes:

• ISDN S/T interface only L1, L2, L5, M1, and M2.

• Reduce to 135% rated value of fuse if Test 3 resulted in open condition.

• L4 and M4 are conducted only if SIDACtor VS

³ 285 VS and then run at voltage level just below VS.

• For test conditions M1, L1, M5, and L5 a wiring simulator (MDL 2 A fuse) is used.

• Compliance means no ignition or charring of the cheesecloth, and/or the wiring simulator does not open.

• If the secondary protector simulator is used (MDQ 1.6), it is allowed to open.

• Tests 2, 3, and 4 are required only if the unit is not a fire enclosure.

• Figure 4.6 and Figure 4.7 show the M (metallic) and L (longitudinal) test connections.
