4.0 Health & Safety
In order to minimise the risk of ill health or accidents when installing and/or servicing pump chambers and
associated accessories, workers must be fully trained and competent. The following guidelines will help
safeguard matters:
• Assessing the risk and working in accordance with the control measures identied.
• Ensure electrical power to the equipment is isolated before carrying out installation or maintenance.
• A suitable rst aid kit must be close to hand.
• The electrical installation must comply with the requirements of BS 7671:2008 ‘Requirements for Electrical
Installations’ incorporating amendment 3:2015.
5.0 Unit location
CAUTION!
The unit is IP2X and is not waterproof, it must be installed indoors or inside a kiosk. The unit must
also be installed in a chemically neutral environment with a relative humidity of <80% and a maximum
temperature of 35°C. It is recommended that the unit is installed o the oor.
Installations not following this guidance will void the manufacturer’s guarantee.
The unit must be positioned where there is sucient air circulation to all the vents and is permanently accessible
for servicing. If using in conjunction with an AlertMaxx2 high level alarm or Rego1, please ensure the units are no
further than a 20m cable length from each other.
MaxxConnect cable can be purchased per 10m (DMS-288). Do not join cables. Run full lengths only.
CAUTION!
This product should only be installed by qualied personnel in accordance with the latest regulations.
Battery Type: Lead-acid
Battery Specification: 24V DC 22Ah
Caution: Replace with same type only
Risk of electric shock & chemical hazard.
Refer to the instruction manual for handling,
disposal & maintenance information.
6.0 Safety
The unit has 240V present at all times and can generate dangerous voltage even if the mains supply is
cut. The black power switch only disables the ability to generate 240V from the battery pack; however, mains
feeds are still live and present supplying the pumps. To be completely safe, remove the fuses from both spurs,
ensure the unit is switched o and disconnect the battery pack.

The PowerMaxx2 can supply one or two pumps (not simultaneously) and have been certied for use on:
• V3
The supplies to the pump/s should be separately fused using non-switched fused spurs and not on
the same ring mains.
7.0 General
8.0 Wiring schematic
Figure 1. Wiring schematic
- The pump is supplied with a 10m cable.
- When only using the standard 10m
cable attached to the pump, the cable
duct should be no longer than 6m.
- If the cable duct requires to be longer
than 6m, please follow the cable
extension guide to select an appropriate
cable core diameter.
The electrical installation must comply with the requirements of

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 conguring 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 conguring 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).
7. Connect the battery pack by plugging in the grey Anderson connector.

11.0 Setupandcongurationoftheunit
1. Replace the side panels of the unit, followed by the lid.
2. Replace the fuses to the spurs supplying the unit and turn on the mains power.
3. Check that the pump/s are receiving power (withtheunitswitchedo) by lifting the oat switches on
the pump/s.
4. Switch the unit on; the screen will display a left to right start sequence, followed by the software release.
5. A C0 will show on the display while the unit checks the environment and the connections. C0 will be present
for approximately 10-15 seconds.
6. If the unit passes the initial cong, a CC will be shown on the display and then the unit will restart and show
-- followed by On and then ip between the charging bars and the -- while the unit calculates the battery
percentage (this can take up to 3 minutes). Once the unit has calculated the battery percent, it will
stop displaying -- and show a gure from 0-99% depending on the state of the battery.
7. If the unit fails to congure correctly (error code below) - switch the unit o, remove the fuses from the spurs,
remove the side panels and lid, redo the connections or set the conguration switches to the correct
positions and then replace the covers and turn the unit back on. If the issue still persists, please call
technical support on 0330 9000 999.
8. If you are connecting an AlertMaxx2 or Rego, please refer to section 14.0 of this manual.

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 qualied 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 landll. 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 qualied 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 specication and in
some instances, not at all.
