WEEE Directive :
At the end of their useful life the packaging and
product should be disposed of by a suitable
recycling centre.
Do not dispose of with normal household waste.
Do not burn.
INSTALLATION
The CT range of current transformers are simple to install; the split core, makes them particularly useful where the mains cable is
already installed. There are, however several important points that must be remembered during the installation process:
Always power down before installation.
If power is flowing through the primary cable and there is no connection to the secondary cable, the secondary terminals
must be connected together and earthed (grounded) to prevent high voltages being induced across the CT terminals.
Below 720 V, the primary conductor requires no insulation, but above 720 V the primary conductor must have adequate
insulation.
