Safety and Maintenance Instructions
Do not use product if physical or liquid damage is present. Contact your local supply
authority for assistance.
The wiring must be performed by a certified installation electrician and must conform to
the prevailing government standards and safety regulations.
This product is not a protection device and so requires the use of a suitable upstream
breaker e.g. 60A rated circuit upstream breaker.
When wiring the meter, ensure that the incoming supply is isolated by switching off the
upstream breaker.
We recommend that if you are connecting aluminium cables to this product, you use
bi-metal lugs.
Ensure that equipment is only accessible to an authorized and trained service person.
Ensure that the appropriate tools are used for the installation.
Ensure that the meter is installed in a dry location and is not exposed to water or
moisture
No sharp objects to be used to press the keypad. If keypad is damaged, please call
service technician.
There are no serviceable parts on the meter. Faulty meters must be returned to the
manufacturer for repairs. Only when these parts are fitted by the manufacturer can the
safety of the appliance can be guaranteed.
Cleaning of the meter must be done by a dry cloth.
Do not use liquids to wipe the meter as this may result in electrical shock.
Do not make any alterations to the appliance, Warranty will be void and safety of the
meter will be compromised.
Never open the casing/housing of the appliance. Tempering with electrical connections
or components and mechanical parts is highly dangerous and can cause operational
faults or electric shock.
Ensure product is disposed of, in accordance with local and national regulations.

Procedure
1. Before setting up the appliance, check it for any externally visible damage.
Under no circumstances should you use a damaged appliance. A damaged
appliance could be dangerous
2. Remove Terminal Tamper cover (Figure2)
3. Mark wall and drill mounting holes (Figure 4)
4. Mount meter on the wall and secure
5. Ensure upstream breaker is in the off position
6. Connect the incoming live supply to L LINE (Figure 3).
7. Connect the incoming neutral supply to N LINE (Figure 3)
8. Connect the outgoing live supply to L LOAD (Figure 3)
9. Connect the outgoing neutral supply to N LOAD (Figure 3)
10. Ensure that all terminal screws are securely tightened, all cables are securely
held in place and that no bare wiring is exposed
11. Secure the terminals & enclosure by threading steel wire through the security
holes and crimping (If required)
12. The meter must be installed on a solid flat surface with a 4mm screw
13. For indoor use only, can be installed in an enclosure or stand alone

Testing the Meter Installation and Sealing the Device
To test the installation:
1. Ensure that the Meter is correctly installed.
2. Apply power to the meter by closing the upstream breaker.
3. Check that the meter is displaying the available credit in kWh. If a zero balance is
displayed, a credit token needs to be purchased and entered into the meter using the
keypad.
4. Enter #100# on the keypad to view the meter serial number.
5. Compare the meter number displayed to the serial number printed on the meter label
and card, to confirm that the numbers match.
6. Turn on an appliance or light in the consumer's premises, to ensure that the consumer
has electricity. In some cases, meter commissioning may be required. For more
information, see the Commissioning the meter section
7. If the meter is working correctly, hand over the meter card and user guide to the
consumer.
