UL Power-limited Wiring Requirements
General
Power-limited and nonpower-limited circuit wiring must remain separated in the cabinet.
All power-limited circuit wiring must remain at least 0.25 inches (6.35 mm) away from any
nonpower-limited circuit wiring.
Furthermore, all power-limited circuit wiring and nonpower-limited circuit wiring must enter and exit
the cabinet through different knockouts and/or conduits.
A typical wiring diagram for the AFP-100 is shown below.
Figure 13 Typical UL Power-limited Wiring Requirements
RTM-8F
Nonpower-limited and power-limited wiring must have a minimum distance of 0.25 inches
wire-to-wire. If this module is used to drive nonpower-limited and power-limited circuits, follow the
instructions below:
1. Skip a set of dry contacts to maintain the 0.25 inches required space between power-limited and
nonpower-limited circuits.
2. If this module is needed to drive power-limited and nonpower-limited relays that are next to each
other, make no connection to the Normally Open contact which separates the two groups of relays.
Refer to the wiring diagram above.
Note:
Refer to "Installing a RTM-8F Module" on page 35, for additional information on the RTM-8F.
