• WARNING! An electric shock can be fatal; electrical connection work may only be carried out by a
competent person
• The earth conductor must be correctly installed and reliably connected
• This device must be equipped with an over-current protection device of maximum 32 Amps (B32)
The single phase should be connected to a 230V/240V nominal AC supply. The supply should run from a
dedicated 32A circuit breaker.
The 3 phase should be connected to a 400V, 4 wire, 3 phase supply. The supply should run from a dedicated 3
pole 32A circuit breaker.
We recommend the use of curve B circuit breakers.
The features an integral 30mA Type-A RCD with 6mA DC leakage detection in accordance with IEC 62955.
Local wiring regulations should consulted to confirm whether an additional upstream RCD is also required.
The unit must be earthed in accordance with local regulations.
When installed on a PME (TNC-S) electrical system it is necessary to protect the consumer from a potential electric
shock that could occur if the combined Neutral and Earth (PEN) conductor on the supply becomes damaged or
disconnected.
includes an additional automatic disconnection device which satisfies the requirements of BS7671:2018
Amendment 1:2020 722.411.4.1 (v) (the 18th Edition IET Wiring Regulations).
This protection device
a) monitors the supply to identify if there is a problem with the PEN conductor and
b) disconnects the supply if a situation arises where the end user might suffer an electric shock
This means that the can be installed without the need for an additional earth rod.
However, if the customer or local regulations require that an earth rod is installed (for instance as part of a TT earthed
system) then this should be connected to the dedicated terminal on the main circuit board using a ring terminal (as
shown below).
