Electrician
The A35M meter should only be installed by a fully qualified electrician who has
knowledge of electricity meters connected with current transformers.
It is the installer who is fully responsible for the safe installation of this meter. It must be
installed to meet the current electrical regulations concerning installation of meters.
EMC Installation Requirements
Whilst this unit complies with all relevant EU EMC (electro-magnetic compatibility)
regulations, any additional precautions necessary to provide proper operation of this and
adjacent equipment will be installation dependent and so the following can only be
general guidance:
Avoid routing wiring to this unit alongside cables and products that are, or could be, a
source of interference.
The supply to the unit should not be subject to excessive interference. In some cases, a
supply line filter may be required.
To protect the product against incorrect operation or permanent damage, surge
transients must be controlled. It is good EMC practice to suppress transients and surges
at the source. The unit has been designed to automatically recover from typical
transients; however in extreme circumstances it may be necessary to temporarily
disconnect the supply for a period of greater than 10 seconds to restore correct
operation.
Screened communication leads are recommended and may be required. These and other
connecting leads may require the fitting of RF suppression components, such as ferrite
absorbers, line filters etc., if RF fields cause problems.
It is good practice to install sensitive electronic instruments that are performing critical
functions in EMC enclosures that protect against electrical interference causing a
disturbance in function.

Wiring Information
Power Supply
The Auxiliary connection must be connected to power up the meter.
Wiring
Electrical and communication connections are made directly to the front of the meter.
Electrical Connections
2.5mm flexible stranded cable is recommended for all main electrical connections. For the
low voltage communication connections we recommend a twisted shielded cable Belden
9841 2 wire or 9842 4 wire or equivalent.
Phasing and polarity of the AC current and voltage inputs and their relationship is critical to
the correct operation.
Programming the meter
When you receive the meter
there will be at least one value
that you must programme into
the meter. This is the current
transformer ratio.
If the meter has been purchased with the intention of using the RS 485
Modbus output then you will have to program the Modbus parameters you
require. See reverse Communication. (RS 485 Modbus)
Pulse Definition
The pulse outputs can be set to generate pulses to
represent kWh/kVarh
Pulse constant: 0.001/0.01/0.1/1/10/100/1000 kWh or
kVarh per Pulse
Pulse width: 200/100/60 Ms.
The pulse output is passive type, complies with
IEC62053-31 Class A.
ATTENTION: Pulse output must be wired as shown in
the wiring diagram below. Scrupulously respect
polarties and the connection mode. Opto-coupler with
potential-free SPST-No Contact.
Contact range: 5~27VDC Max. current Input: 27mADC
