FIXING TO THE WALL
Fix the provided blue top xing bracket to the wall via the 3 pre-drilled holes. Screws are provided. It is
important to x the bracket level. Attach the MultiPlus to the top support bracket using the lugs on the rear of
the unit. Complete the x by screwing the bottom of the MultiPlus to the wall via the bottom 2 holes using the
screws provided. Carefully mark out the hole centres, then take the MultiPlus off the wall to drill the holes.
Note: Rawl plugs will be required for the screws for certain wall types (not supplied).
CONNECTION OF BATTERY CABLES
1. Use an insulated box spanner in order to avoid shorting the battery. Avoid shorting the battery cables
2. Connect the battery cables: the + (red) and the - (black), to the battery. Reverse polarity connection (+ to –
and – to +) will cause damage to the product and will void the warranty
3. Secure the nuts tightly in order to reduce the contact resistance as much as possible
CONNECTION OF THE AC CABLING
This is a Safety Class I product (supplied with a protective grounding terminal). Uninterrupted protective
grounding must be provided at the AC input and/or output terminals and/or chassis grounding point located
externally on the product.
The MultiPlus is provided with a ground relay that automatically connects the Neutral output to the chassis if
no external AC supply is available. If an external AC supply is provided, the ground relay H will open before the
input safety relay closes. This ensures the correct operation of an earth leakage circuit breaker that is connected
to the output. An uninterrupted grounding can also be secured by means of the grounding wire of the AC input.
Otherwise the casing must be grounded.
The mains -input & output terminal connector can be found on the bottom of the MultiPlus. The mains cable
must be connected to the connector with a three-wire cable via the terminal blocks found on the printed circuit
board. Use a three-wire cable with a exible core and a cross section of 2.5 mm².
PROCEDURE
Proceed as follows to connect the AC cables:
• The AC input cable (from mains) can be connected to the terminal block “AC–in”. From left to right: “PE”
(earth), “N” (neutral) and “L” (phase). The AC input must be protected by a fuse or magnetic circuit breaker
rated at 16A or less, and cable cross-section must be sized accordingly. If the input AC supply is rated at a
lower value, the fuse or magnetic circuit breaker should be down sized accordingly
• The AC output cable (to control panel or pump 1) can be connected directly to the terminal block “AC-
out-1”. From left to right: “PE” (earth), “N” (neutral) and “L” (phase). With its PowerAssist feature, the Multi
can add up to 3kVA (that is 3000 / 230 = 13A) to the output during periods of peak power requirement.
Together with a maximum input current of 16A, this means that the output can supply up to 16 + 13 = 29A.
An earth leakage circuit breaker and a fuse or circuit breaker rated to support the expected load must be
included in series with the output, and cable cross-section must be sized accordingly. The maximum rating
of the fuse or circuit breaker is 32A. Do not use AC output 2.
QUICK INSTALL GUIDE
The steps in bold are indicated on the gure on page 8:
1. Screw the top bracket to a suitably strong substrate using the screws provided. Rawl plugs will be required
for the screws for certain wall types (not supplied)
2. Place unit onto the bracket using the lugs to the rear of the unit. Screw the bottom of the unit to the wall
3. Unscrew and remove the front panel. Note: All cables will pass up though the bottom of the unit prior to
connections being made
4. Wire AC IN with correctly rated mains cable. Add 3-pin mains plug or wire to a switched fused spare,
both of which should be tted with a 13amp fuse. Do not plug in or turn on at the spur at this stage
5. Wire AC OUT with correctly rated mains cable from either a Newton automatic pump, or from the ‘pump
2’ connection of the CP2 or CP9 control panel
6. Wire the temperature sensor cable into the T-SENSE terminal
7. Connect the black battery cable to the left Negative terminal
8. Connect the red battery cable to the right Positive terminal
9. Connect the black battery cable and the temperature sensor cable to the negative terminal on the battery
10. Connect the red battery cable to the positive terminal on the battery
11. The system will start running off the batteries
12. Plug the AC IN into mains power or switch on the fused spur

OPERATION
On/Off/Charger Only Switch
For all operation as a battery backup system, the switch should be in the “on”, position. This results in the
product being fully functional, providing the pumps with thorough power during times of normal inverter
power during power outage. When mains power is not interrupted, the unit will also charge the batteries.
Charge states (please also see LED Indications below):
• Bulk - Heavy and fast charge for batteries that are very or fully depleted
• Absorption - Final top up charge at a lower charge rate than Bulk
• Float - Trickle charge for when batteries are fully charged to replace charge that is lost over time. This
ensures that the batteries are always fully charged
• If the voltage at the “AC-in” terminal is not within specications, during a power outage, for example, the
inverter will switch on, continuing power to the pumping system until the battery(s) is depleted
• There is no need to switch the unit to “charger only” mode
LED Indications - Standard operating parameters of inverter and charger
