INSTALLATION INSTRUCTIONS
5. Connecting to power supply
The LM2 is factory set as a 220 volt unit. To operate at 110V, transfer the brown wire on transformer
to the 110V side. See inside chassis for directions.
Use #12/2 insulated wire and conduit.
Connect the power supply wires to the first two terminals. It does not matter which of the two
terminals but they must be connected to the two load terminals. (Refer to wiring diagram.)
Connect ground wire to ground terminal (fourth terminal). Note: the third terminal is a spare.
Please note:
The power pack must be wired
to the pump switch terminals.
This unit is factory set to be
wired to 220V but can be
converted to 110V. See inside
chassis for directions.
Option A: Wiring to a pump switch or automatic timer
The power pack must be wired to the load side of the pump switch or timer, so that the salt system
is powered only when the pump is powered. Any other type of installation will void the warranty.
Option B: Wiring via an auxiliary relay at the Pool Automation Controller
Using this method the LM2 mains power is connected to an auxiliary relay in the Pool Automation
System. The LM2 unit is switched on and off as determined by the Pool Automation System settings
for the auxiliary relay.
The “Output Setting” and the selection of “Super Chlorinate” must be selected at the LM2 control
panel initially and the LM2 will retain these settings when switched on by the Pool Automation Sys-
tem until they are manually changed.
