Output Circuit Breakers:
Wires can be landed directly to the circuit breakers since these are
UL489 type which are approved for field wiring.
Maintenance Bypass Switch:
This option will have an input terminal block for landing the incoming
AC feed wires. Connect the incoming AC feed to this terminal block.
Trip Alarms:
This option uses an auxiliary contact on the side of the output breaker
to indicate to the controls that the circuit breaker has tripped.
Switched Output:
This option has a Switched Command which controls the Switched
Output. Switched Outputs are provided with Circuit Breakers.
4.3 Installing the Output Wires
Connect the load wires to the Normally-On output terminal blocks. If your system
has output breakers, connection directly to these circuit breakers are permitted
since these are also UL489 rated. Other output configurations could include
Normally-Off or Switched outputs which also use circuit breakers as the
connection points. Please refer to your systems part number for your specific
output configurations. Ensure that the connections to these terminal blocks or
breakers are secured by briefly tugging the wires. See Section 7.4 thru 7.5 for
further load type details.
NOTE – AC Input and AC output wires must be run in separate conduit or raceways
per NEC ARTICLE 700. Please ensure all codes and standards are observed.
NOTE – LM/LMOPT Series requires that the Neutral and Ground potential does not
exceed 5 VAC for proper function. Anything above 5 VAC typically indicates that
there may be an issue such as grounding, inadequate conductor size or continuity.
This should be looked at immediately as it could cause a safety concern.
NOTE – Neutral and ground should never be tied together anywhere in the LM/
LMOPT Series. Always keep Neutral and Ground wires separate to ensure no
shorts occur.
NOTE – Neutral (NEU) in the LM/LMOPT Series is common to both the Input and
Output. Never mix Neutrals for the building wiring (Non-Emergency) with the
Emergency wiring. Dedicated wiring is required by NEC code ARTICLE 700.
4.4 Special Options
Custom units are available (Section 8 Specifications – Ordering Guide) and these
may cause the construction to differ from standard models.
