9.0 Wiring a standalone PowerMaxx2
1. Remove the fuses from the spurs that will power the pumps being used with the PowerMaxx2.
2. Ensure the power switch of the PowerMaxx2 is in the OFF position.
3. Remove the PowerMaxx2 lid and side panels from the unit.
4. If you are conguring the unit with one pump, t two large cable glands into the primary side of the unit
and two blanking plugs into the secondary side of the unit.
If you are conguring the unit with two pumps, t two large cable glands into the primary side of the unit
and two large cable glands into the secondary side of the unit.
If you are connecting an AlertMaxx2, t a small cable gland into the small hole above the secondary holes.
5. Using the cable glands on the back of the PowerMaxx2, feed the power and pump cables through and to
the correct terminal blocks on the lower circuit board.
There are two connector blocks on the lower circuit board: PRIMARY and SECONDARY. The primary
connector block should always have a connection, as this is the supply that charges the PowerMaxx2.
6. Connect the supply to the “From Mains” and the corresponding pump to the “To Pump” (gure 2).

12.0 Principals of operation
Normal operation
In normal operation, the power bypasses the unit which acts as a junction box, and this then feeds the pumps
directly. Pump supply #1 (primary) also charges the battery.
Backup operation
When the unit senses that the power is down, the unit enters backup mode. To save power, the battery backup
will periodically and dynamically test if the pump/s need power (oat up) using a system called DyPol (from
10-180 seconds depending on how often the pumps are cycling). If the pump/s need power, it will serve the
pump requesting power for as long as needed or until the battery is depleted.
If two pumps are connected and both supplies have failed it will serve both pumps in a rotational manner giving
equal priority until the power returns or the battery backup is depleted.
If the secondary power has failed, it will serve the secondary pump as required from the battery. However, it will
also charge the battery from the primary spur, when the secondary pump does not need power.
Charging
After any power failure, the battery is always charged. The battery is also charged and topped up every 21 days.
This process can take up to 5 hours for a PowerMaxx2 to fully charge an empty battery.
13.0 Battery life & servicing
The battery has a nominal life span of 3 years and is displayed on the unit with a bL+%. This life span is
shortened over time and also by the following:
• Temperatures above 25°C.
• The number of discharges (the number of times the unit has been used without mains power).
• The depletion level when discharging and the number of times the batteries are used. Extended periods
providing backup power will impact battery life.
Replacement of the battery pack should be done every 2-3 years to ensure the maximum backup time. In some
cases, the battery may need earlier replacement. This will be indicated by an S2 on the PowerMaxx2.
Servicing of the battery pack should be performed by a qualied service person with knowledge about batteries
and the required precautions. The battery pack should be replaced with the same type the unit is installed with.
This information can be found within the unit or on page 5.
WARNING!
Do not dispose of batteries in a re. The batteries may explode.
Do not dispose of batteries in landll. Please recycle safely at your local recycling plant.
Do not open or damage batteries. Released electrolyte is harmful to the skin and eyes and may be toxic.
• To reset the S2, see section 21.0 - U6.
Please note, the battery service reset should only be performed by qualied personnel and only when the battery
has been changed. It is the owner’s responsibility to ensure the battery is replaced when required. If the battery
is not change when needed, the unit will not be able to backup the pumps according to the specication and in
some instances, not at all.

14.0 Connecting an AlertMaxx2 or Rego1 (if purchased)
PLEASE NOTE
The AlertMaxx2 must have the pump/s wired into it. The AlertMaxx2 must be installed in series to
the PowerMaxx2, this means the AlertMaxx2 must be installed in between the PowerMaxx2 & the
pump/saspergure5onpage12.
The PowerMaxx2 can be connected to an AlertMaxx2 or Rego1. Battery backup capacity and condition are fed
directly to the SideWinder Tech software when connected to the internet.
The PowerMaxx2 is supplied with 3m of 4 core MaxxConnect family cable.
15.0 MaxxConnect cabling
The units are to be a maximum of 20m cable distance apart. MaxxConnect family cable can be purchased per
10m (DMS-288). Do not join cables. Run full lengths only.

2. Wire in the MaxxConnect cable according to the wiring schematic on page 12.
3. Congure the switches are per section 10.0.
4. Reconnect the batteries in the battery backup and AlertMaxx2/Rego1.
5. Ret the fascia/covers and power on the mains and units.
6. The battery backup should now startup with a ashing decimal dot indicating it is trying to nd the
AlertMaxx2/Rego1. This could take up to 2 minutes to clear.
CAUTION!
MaxxConnect misconnections will destroy one or all connected units (this can be detected by the
manufacturer) and void the guarantee.
The MaxxConnect introduces two new error codes to the PowerMaxx2 and one new error code to the
AlertMaxx2/Rego1:
1. PowerMaxx2 - ashing decimal dot - Trying to nd the AlertMaxx2/Rego1
2. PowerMaxx2 - E5 - Cannot nd the AlertMaxx2/Rego1
3. AlertMaxx2/Rego1 - E5 - Cannot nd battery backup
If the mains power fails, the AlertMaxx2 and Rego1 will keep themselves operating and charging from the battery
backup. Please note, this will reduce the resilience of the battery backup.
