SYSTEM DESIGN CONSIDERATIONS
•
The LSP should be mounted so that the connected electrical panel is within reach of the LSP’s flexible
conduit fitting. The fitting extends 13" beyond the left face or 9 ” beyond the right face of the LSP
enclosure. Ensure that the electrical panel has adequate wiring space for LSP conductors and
connections. Suitable junction boxes and conduit may be used to route and/or extend LSP
conductors if needed. For voltage drop calculations, assume LSP conductors add 15 one-way-feet to
the circuit.
•
An LSP requires an always-on Internet connection, either via Ethernet (preferred if available) or 2.4
GHz Wi-Fi. Communication wiring requires materials for routing in 3/4" liquid-tight conduit.
• When used for energy management, the LSP will be most effective when used to shed heavy
discretionary loads. These are loads greater than 15 amps that may be desired during grid outages
or other energy-constrained situations. Lumin can shed such loads automatically while permitting a
user to manually re-enable them at their discretion.
More information about circuit selection is
provided in the required Lumin Certified Installer Training. In order to shed discretionary loads
in response to grid conditions, a connection to non-backed up utility grid power is required for
the LSP grid detection circuit. See pg. 28. This will require wiring beyond the LSP’s connected
electrical panel . Controlling the circuit that powers the Internet connection is not
recommended ; manual control of the LSP will be lost when this circuit is switched off.
• The LSP does not replace the need for standard circuit breakers. Lumin does not provide overcurrent
protection, ground fault protection, arc fault detection, or other safety functionality that circuit
breakers provide.
• The LSP uses current transformers (CTs) to measure overall power flows. Correct placement of these
CTs may require
wiring beyond the LSP’s connected electrical panel . See pg. 23.
•
If the LSP is configured to automatically shed loads exceeding backup capacity following a grid
outage, a Temporary Power Unit (TPU) accessory module may be required if the transfer to backup
power takes more than 70 ms. Without the TPU, the LSP could lose power before backup transfer
completes, and circuit disconnection would be delayed until after the LSP powers on with the backup
source. If unsure about transfer times,
contact Lumin to determine if a given system requires a
TPU . The TPU may be installed inside the LSP enclosure before (preferred) or after LSP purchase.
