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.
