WHOLE HOUSE AUTOMATIC TRANSFER SWITCH - ALL aXis CONTROLLER
battery Charger Wiring
The aXis Controller
HSB contains a 24V battery charger that is
®
powered by 120V AC. The battery charger receives 120V AC power
from the aXis Controller
ATS using the single fuse block located
®
in the bottom left corner of the ATS.
1. Run two wires from the ATS to the HSB for the battery
charger circuit.
The battery charger circuit is 120V AC, 1 amp maximum.
Wires need to be sized accordingly.
Wiring can run in the same conduit as the L1, L2, Neutral and
Ground wires from the previous section provided:
1a. Battery charger wire has an insulation rating equal to or
greater than 264VAC.
1b. Battery charger wire is suitable for outdoor installation.
1c. Allowed by local code and meets NFPA 70.
2. ATS Connections for battery charger.
2a. L1 - Bottom terminal of the fuse block in the ATS.
2b. Neutral - Neutral block.
See picture below for location of fuse block and neutral block.
3. HSB Connection for battery terminals
3a. L1 and N will connect to a terminal located near
the connection points of L1, L2, N, and G. Refer to
aXis controller™ HSB installation manual for more
information.

Utility Sensing Fuse block
The utility sensing fuse block is not used in a typical installation.
The fuse block is only used when connecting the Champion aXis
ATS to a non-Champion HSB that monitors utility voltage to control
automatic generator start/stop. The potential voltage between the
two fuses is 240V AC.
Do not use the utility sensing block for the battery charging circuit.
The battery charging fuse block is located next to the utility
sensing fuse block.
Low Voltage Control Relays
The aXis Controller
ATS has two low voltage relays that can be
®
used to manage the load of air conditioners or other devices that
utilize low voltage controls. The ATS's two low voltage relays are
called AC1 and AC2 and are found on the aXis control board as
shown in the picture below.

Pin 1 Pin 2 Pin 3
CONNECTING TO AC1 AND AC2
For air conditioner or other low voltage controls, route your low
voltage wiring into the ATS using code appropriate conduit and
fittings. Connect the wiring to pin 1 and pin 2 of either AC1 or AC2
as shown in the diagram above. Please note that AC2 has three
pins available, of which, pin 3 is not used.
