7.1 Safety instructions for electrical connection
Prior to connecting, check that the voltage / frequency on the type plate corresponds to the
local mains conditions.
There is a risk of fatal electric shock when touching
electrical components.
◆
Carry out all installation and connection work only in an isolated, zero-volts state.
◆
Disconnect all phases of the mains power supply cable and secure it to prevent any
reconnection.
◆
Check the system for a zero-voltage status.
Incorrect wiring may lead to short-circuits and
destroy the device.
◆
Follow the pin assignment detailed in the wiring diagram.
◆
Follow all the electrical connection specifications in the operating instructions of your
tubular motor and that of the external controller (when using E1/E2).
Connection of a second phase to E1 or E2 will cause the
Troll Basic DuoFern to be damaged.
◆
When inputs
E1 / E2
are used, they must always be connected to
the same phase
.
◆
If another phase is connected, the
incorrect mains voltage (380 V / 50 Hz)
will be
applied to the inputs and damage the Troll Basic DuoFern.
