How many 261/16 Clipsal saddles are there in a carton?

There are 50 16mm saddles in a carton.

Note: This information can be found in your Clipsal pocketbook right next to the part code.

Is there an extension ring to suit the 343?

Yes, there is the 93ER and also the 249/12 or 249/25.

Are the Clipsal Conduit Clips available in Electric Orange?

No, they are only available in grey.

This applies to the 280/16 (16mm), 280/20 (20mm), 280/25 (25mm), 280/32 (32mm), 280/40 (40mm) and 280/50 (50mm).

How to calculate Energy readings from the raw Integer register data on an Energy Meter

The energy values are stored across two 16-bit integer registers on an energy meter. 

Product Line
Energy Meter

Reading and converting Modbus register values

The Energy Meter stores energy across two 16-bit integer registers.

Register #1 and Register #2 (Modbus address 257/258 for Register #1 and 259/260 for Register #2). Register #2 is the High WORD and Register #1 is the Low WORD. 

The Multiplier/Divisor table states that both of these registers must be divided by 32 to obtain the real value from the raw data.
The Multiplier/Divisor should NOT be applied to both registers. It is applied to the final value of both registers.

To calculate the Energy the registers must first be arranged as the register list states [2] is the High word and [1] is the Low word.

To make [2] the High word it needs to be shifted to the left 16 bits.
To accomplish this multiply the value in [2] by 65,356.
You will then add this value to the value in [1].
The final value will be divided or multiplied by the correct scaling value. Please see the example listed below.

For this example we will assume an Energy Meter with 300 amp CTs. According to the Integer Multiplier/ Divisor table, 300 amp CTs will give a divisor value, (d), of 32 and a multiplier value, (m), of 0.03125.
We will assume the following register values.
Register #1 = 29,586
Register #2 = 31

Using Divisor Table
kWh = ([R2]*65,536+[R1])/d
kWh = (31*65,536+29,586) / 32
kWh = 64412.56

Using Multiplier Table
kWh = ([R2]*65,536+[R1]) * m
kWh = (31*65,536+29,586) * 0.03125
kWh = 64412.56

*Note the divisor will not always be 32 and the multiplier will not always be 0.03125. For the correct values please see the Integer Multiplier Table.

Where are I/O modules installed on a PM8000 meter

User wants to know where to install I/O modules on a PM8000 meter.
Product Line:
PM8000 meters
METSEPM89M2600 (Digital I/O module)
METSEPM89M0024 (Analog I/O module)

I/O modules installation

*Warning:  Installation and maintenance of this device should only be performed by qualified, competent personnel that have appropriate training and experience with high voltage and current devices. Failure to follow the instructions / warnings in the Meter Installation Guide can result in permanent damage to the meter, severe injury or death.

There are 2 methods to install I/O modules on a PM8000 meter. The method to choose will depend on your PM8000 model number

If meter is PM8240 (Panel mount meter with integrated display)
I/O module to be installed on the back of the meter. 
1) remove connector's cover on back of the meter
2) Make sure that connectors on meter and I/O module align with each other. Attach I/O module to the back of the meter.
3) secure the I/O module in its location by a 5mm (5/16 in) screw
4) reattach connector's cover that was removed in step 1 to the back of I/O module
See illustration below:

If meter is either PM8243 or PM8244 (DIN rail mount meter)
I/O module to be installed on the side of the meter:
1) remove connector's cover from side of the meter
2) Hang the I/O module on your DIN rail
3) Secure I/O module to the DIN rail using Mounting clip.
4) Move I/O module using the DIN rail and attach it to the PM8000 meter> You should hear a click.
5) Secure the I/O module to the meter using a 5mm (5/16 in) screw.
6) reattach connector's cover that was removed in step 1 to the back of I/O module
