230 V terminals
a) Permanent connection (standard)
In the case of 230 V terminals, power is supplied via the
transformer on the preassembly plate.
The device is designed for a permanent con-
nection to the power supply circuit only.
It must be connected by a qualified electri-
cian only.
The power supply circuit for this device
requires a suitable, easily accessible power
isolating device with a minimum contact
gap of 3 mm and a fuse element to protect
against short circuits, both already provided
on site.
The earth conductor must be connected.
b) Plug-in connection (deep casing only)
An earthing connection cable is used to connect to the
power supply circuit. This cable is available as an accessory.
Use the enclosed clip to install the earthing
connection cable and ensure that is not
tensioned.
The earth conductor must be connected.
