PRODUCT OPERATION
Pressac Communications Limited (the original manufacturer) declares
that the product branded
The Pressac Wireless CT Clamp needs to be commissioned before use.
There are 2 ways in which the unit can be commissioned.
CT Clamp 63A – 868 MHz
CT CLAMP

63A – 50/60Hz – 315/868/902
PRODUCT SPECIFICATION
DECLARATION OF CONFORMITY
1.
CT Clamp 63A – 315 MHz
CT Clamp 63A – 902 MHz
satisfies the requirements of Annex II of the R&TTE Directive and has
been independently tested & found compliant with the essential
requirements of:
BS EN 61326-1 2013 Electromagnetic Compatibility

Self-powered learn
As the unit is 100% energy harvesting, it can only perform a self-powered
learn if it is clipped around a suitable conductor and there is a minimum
of 1A flowing. If this is the case, clip the CT clamp around the conductor
and wait for a period of 30 seconds. With a suitable tool (sharp, nonmetallic, non-conductive element), depress the learn button which is on
the underside of the product. The LED should briefly flash. The Pressac
Wireless CT Clamp is now commissioned.

EnOcean® network manually. To do this you will need the unique
EnOcean® ID of the Pressac Wireless CT Clamp and also it’s EnOcean®
Equipment Profile. The EnOcean® ID and the EEP are printed on the
product label on the Pressac Wireless CT Clamp.
The Pressac Wireless CT Clamp is designed to measure and report the
AC current flowing in a single conductor. Powered from the measured
conductor itself, the measured current value is reported every 10 seconds
(or every 30 seconds if the current is found to be below 3A) using the
industry standard, wireless EnOcean® protocol. Capable of measuring
currents up to a maximum of 63A (50Hz or 60Hz), the Pressac Wireless
CT Clamp is easily installed with no disturbance to the measured conductor.
DISPOSAL INSTRUCTIONS
The symbol shown here, and on the product, means that this
product is classed as electrical or electronic equipment, and
should not be disposed of with other household or commercial
waste at the end of its working life. The Waste Electrical and
Electronic Equipment (WEEE) Directive (2002/96/EC) has
been put in place to recycle products using the best available
recovery and recycling techniques to minimise the impact on
the environment, treat any hazardous substances, and avoid
landfill disposal.

WIRELESS GUIDELINES
To be able to measure the current within a single-phase cable, the
Pressac Wireless CT Clamp must be correctly clipped around the cable,
ensuring that the ferrite cores within the clamp reliably and consistently
touch each other. In permanent installations, the unit can be cable tied to
the conductor for added security.
Once installed and commissioned, the value of electric current is
transmitted every 10 seconds (for values of current between 3A and
63A). For smaller values of current (between 1A and 3A) the reporting
period is reduced to every 30 seconds. If a current lower than 1A is
flowing, the Pressac Wireless CT Clamp will not report any information or
transmit any EnOcean® telegrams.
The product uses an EnOcean® STM300 Module for transmitting the data
wirelessly. It supports the following EEPs (EnOcean® Equipment
Profiles):
In typical building conditions, where there are no obstructions causing
screening, EnOcean® devices will normally interoperate at a range of
30m line of sight (LoS)
Typically in a building, there are a number of factors, which can reduce
this LoS range further.
Material reduction vs. LoS
Range
Wood, drywall, glass (uncoated with no
metal
0-10%
Brick, plaster board
5-35%
Metal, concrete, mirrors
10-90%
*EEP A5-12-01
*The EEP standard, A5-12-01 defines the measured units as Watts. This
device reports the units in Amps. A new EEP to support this device in
reporting Amps has been submitted to the EnOcean® Alliance and is
pending approval/release.
TECHNICAL SUPPORT
Furthermore, the angle at which radio waves penetrate obstructions also
has a greater or lesser effect on signal quality. Where an obstacle to
transmission is present, the signal should propagate perpendicular to the
obstruction for best results.
PRODUCT MAINTENANCE
Tel: +44 (0) 115 936 5238
E-mail: [email protected]
On receipt of the product, inspect it carefully to ensure no damage has
occurred during shipment. If damage is evident, or it fails to operate
according to specifications, contact your dealer, or Pressac. The features
that are of utmost importance to maintain within the life span of this
product are the ferrite cores. It is important that the surfaces of each side
of the ferrite cores are kept clean (which can be achieved using the
alcoholic wipes provided), so that when the unit is clipped around a cable,
the ferrite cores are touching each other. Failure of the surfaces to mate
will cause incorrect readings to be measured and reported.
