5. Electrical Connection
Work on the electrical system or equipment must only be carried out by a skilled
electrician himself or by specially instructed personnel under the control and
supervision of such an electrician and in accordance with the applicable electrical
engineering rules.
5.1.1. Connection of SIMA
SIMA can be supplied with different voltages. Before inserting the power supply plug ensure that the
mains switch is in position OFF and verify that the existing power supply on site is equivalent to the
power supply of the SIMA Master Station.
Insert all required plugs according to the connectors diagram (clause 12.4, p. 58).
It is recommended that the shielding of all interface cables is properly connected to the ground
potential in the control cabinet (use shielding clamps).
5.1.2. Connection of actuator / controls
Perform the connection of the actuator / controls according to the operation instructions enclosed
with the delivered AUMA actuator.
For more details, observe the complete operation instructions of AUMA actuator controls,
see
5.1.3. Connection of additional field devices
As SIMA is based on standard fieldbus communications, other field devices may be integrated in the
scope of control on request.
If repeaters are used, be sure to take care of the power supply, as a loss of this
energy supply will lead to a complete failure of the repeater and therefore to a loss
of communication to all succeeding actuators.
