4 -APC UNIVERSAL TRANSFER SWITCH CONFIGURATION
NOTICE
APC universal transfer switch is provided for use
with freewatt Plus system and is not intended
for emergency backup power applications.
Manufacturer is not responsible for the use of this
switch in any manner not outlined in this manual or
APC UTS6H Installation Guide.
4.1 APC Universal Transfer Switch
freewatt • PLUS System incorporates APC Universal
Transfer Switch as load panel in Back-Up Power Mode.
UTS6H requires customized confi guration in order
•
to operate effectively with freewatt PLUS System.
Following section will explain confi guration process for
this component.
Set-up for APC Universal Transfer Switch (UTS6H)
•
involves following System Confi guration and Setup
section in UTS’s Installation Guide.
Important notes about this product: •
WARNING
Improper confi guration may result in improper
operation of freewatt PLUS System in Backup Power
Mode. Failure to follow these instructions could cause
malfunction of system and result in death, or serious
bodily injury. Read and follow these instructions
before attempting installation, commissioning or
operation.
!
NOTICE
Use only outlet mounted AFCI and GFCI circuit
interrupters with the UTS. Do not connect the UTS
to circuits utilizing AFCI or GFCI circuit breakers in
the main electrical panel.
Circuit 1
Circuit 1 includes Load attached to Circuit-labeled “1” •
and convenience outlet on front of UTS6H, together
must consume less than 15 amps when system is
operating in Backup Mode. If not using Uninterruptable
Power Supply (UPS), it is recommended to use circuit
1 to power freewatt PLUS System’s low power
condensate pump.
Circuit 1 is only powered by MCHP when in Backup
•
Power Mode. It will not be powered from UPS if
UTS6H is equipped and confi gured to use UPS. It
is recommended that UPS be plugged into front
convenience outlet and therefore is powered by Circuit
1.
4.2 Uninterruptible Power Supply (UPS)
If using UPS to power “uninterruptable” loads, plug UPS •
power input cord into convenience outlet to charge UPS
batteries when MCHP Backup Power is available. Note,
UPS batteries will also 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 by UPS in Backup
Mode. Typically, low power circuits, such as computers
or security systems, are confi gured for use with UPS.
4.3 Non-Delayable & Delayable Circuits
Circuit assigned to • freewatt boiler shown in examples
on Circuit 3 must be confi gured as “Delayable-No” to
ensure freewatt PLUS 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 of example where UPS is used
and circuit source is confi gured as “UPS” or “Un-
interruptable”.
4.4 Hardwire Kit
UTS6H is supplied with Hardwire Kit used to connect •
freewatt PLUS Transfer Switch to UTS6H. See
Parts, Kits & Optional Accessories for kit part number.
Hard-wire kit is installed in UTS6H and accepts cable
delivering Honda generator’s backup power output.
Follow electrical schematics in this manual and
instructions in Hard-wire Kit for installation.
NOTICE
Mark all breakers in Electric Panel as moved to
UTS6H for future reference.
NOTICE
Circuits 5 & 6 must be connected to circuits in
opposite phases to ensure 240VAC is present across
two circuits, to allow UTS6H to monitor utility power
supply and sense power outage.
Circuit 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 also be connected to circuits that are in
opposite phases, so 240V is present across two circuits.
Allows UTS6H to monitor Utility power supply.
