9.1 Safety instructions for electrical connection

Danger due to electric shock when working on

all electrical systems.

◆ The electrical connection and all work on electrical systems must only be carried out by

a qualied electrician in accordance with the connection instructions in these operating

instructions.

◆ 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.

◆ Prior to connecting, compare the information about voltage / frequency on the device

with that of the local electrical grid operator.

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 specications 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.
