supply configuration is changed. Failure to reprogram the SRD may allow critical system
failures to occur without an appropriate Telco alarm. Failure to recognize an alarm condition
could result in loss of data or damage to equipment.
A DC power terminal block is provided at the rear of each DC power supply. For best results (to meet
maximum current requirements) all four terminals (2+ and 2–) should be used. Each terminal is rated for
15A.

The terminal block will accept standard terminal lugs size Newark stock # 81N1501 type
CRS-T0-1406-HT that accept 14 AWG wire gauge. The width (W in Figure 12-3) of the lug can be no larger
than 0.25 inches.
