UTS6/UTS6H

Circuit No. Load Description

Circuit 1

Circuit 1 includes load attached to Circuit 1 connection plus convenience outlet on front of UTS6H, together must consume

less than 15 amps. Recommended to use Circuit 1 to power freewatt

System's low power condensate pump.

Circuits 5 & 6

Although all UTS circuits do not need to be used, Circuits 5 & 6 must be connected to main circuit panel and must receive

power for UTS to function. Circuits 5 & 6 must be connected to circuits that are in opposite phases, so 240V is present

across two circuits. Allows UTS6H to monitor utility power supply.

Uninterruptible Power Supply (UPS)

If using UPS to power "uninterruptible" loads, plug UPS's AC power cord into convenience outlet to charge UPS batteries

when MCHP backup power is available. Note: UPS batteries will be charged from convenience outlet when grid power is

available.

Follow UPS and UTS6H instructions for sizing UPS for loads conﬁ gured to be powered in backup mode. Low power circuits,

such as computers or security systems, are typically conﬁ gured for use with UPS.

Non-Delayable & Delayable Circuits

Circuit assigned to freewatt

furnace must be conﬁ gured as "Delayable-NO" to ensure freewatt

system always has

power when in backup mode, otherwise system may not operate correctly.

All other circuits must be conﬁ gured as "Delayable- Yes" except in case where UPS is used and circuit source is conﬁ gured

as "UPS".
