4.0 AC CONNECTIONS
WARNING – Only qualified personnel that are familiar with AC and DC
installation techniques and codes (such as an electrician) should perform
the Installation.
WARNING – The LM/LMOPT Series contains lethal AC Voltages. Due to the
hazard of high voltage electrocution, always shut down all sources of
power before you install, maintain, or service the unit.
WARNING – Remove all rings, watches, and other jewelry before doing any
electrical service or installation work. Always wear protective clothing and
personal protective equipment (PPE) that is suitable such as eye protection
when working near batteries.
NOTE - Always check the system’s rating label located on the cabinets left
side interior wall and also the system’s door.
Use copper wire only – read all warning labels provided in the cabinet!
4.1 Removing the AC Breaker cover
To access wiring to the breakers, remove the two ¼-20 bolts from the
plastic breaker cover with a 3/8 socket or nut driver.
Note - This cover conceals the wiring area and also provides a safety barrier
so fingers do not inadvertently touch live parts after installation. Always re-
install the AC Breaker cover to prevent accidental contact with live wires
during routine maintenance.
4.2 Installing the Input Wires
1. Ensure that the System ON/OFF switch is in the OFF position before
starting.
2. Ensure that the incoming feed AC voltage matches the voltage rating
of the model you have. Please refer to the systems rating plate label.
3. Ensure that the feed breaker from the panel has enough ampacity
to allow for the full rating of the input current required on the
systems rating plate.
Once the Utilities AC input feed voltage and Feed breaker size is confirmed,
connect the utilities feed AC wires to the systems Input circuit breaker (UL489
rated for direct connection), Terminal Block NEU (Neutral) and grounding
terminal block (GND). Ensure wire connections are secure to all connection
points by briefly tugging the wires to ensure a solid, secure connection with low
continuity.
NOTE – AC Input wiring may have to be landed to a Terminal Block instead of the
Input Breaker if a Bypass Switch or Mixed Voltages are present on your system.
