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 qualified 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 specifications in the
operating instructions of your tubular motor.
Connection of a second phase to E1 or E2 will cause the
Troll Standard 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 Standard.
