General considerations

 

 

 

NOTICE!

 

All wiring except the battery terminal and primary AC power is power-limited. Phone lines are

also generally considered to be nonpower-limited.

Power-limited and nonpower-limited circuit wiring must remain separated in the cabinet by at least 0.25 in. (64 mm) and must enter and exit from the cabinet through different knockouts or conduits. Phone lines are generally considered to be nonpower-limited, so the cables for networking cards should not be run through the same knockout as the phone lines.

Avoid shielded or twisted-pair wire except for special applications where a reduced length of wiring (roughly 50%) is acceptable for tolerating a harsh electrical environment. Consider fiber optics for these applications.

A network group can be connected as Class A Style 7 or Class B Style 4. Class A configuration is recommended because this allows the panels in a network to communicate with each other, ensuring circuit operation in the event of a single break in the wiring.

The following table lists the trouble conditions that result when a fault exists on the network (SLC according to UL 864).
