UL Power-limited Wiring Requirements
2.6 UL Power-limited Wiring Requirements
Power-limited and nonpower-limited circuit wiring must remain separated in the cabinet. All power-limited circuit
wiring must remain at least 0.25" (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 MS-9200 is shown in Figure 2-7.

RTM-8F UL Power-limited Wiring Requirements
Nonpower-limited and power-limited wiring must have a
minimum distance of 0.25" 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" 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 sepa-
rates the two groups of relays. Refer to the typical wiring
diagram to the right.
Refer to Figure 2-16, “RTM-8F Relay Transmitter Module,” on
page 34, for additional information on the RTM-8F.
