Electrical Connection - Resol VA300 Manuel

1. Installation
1.1 Montage
Î
Set the actuator (SVA-NC type only) to the manual mode
position, see page 14.
Î
Attach the electrothermal actuator to the valve by means
of a union nut.
Note
The valve can be mounted in any position, but the actu-
ator must not face downwards.
The installation of the valve must be carried out in accordance
with the approved technical regulations. The installation must
be carried out by an approved technician! Pay attention to the
valid loacal regulations!

1.2 Electrical connection

The connection has to be carried out in accordance with the
connecion scheme.
The cables of the actuator have to be connected to the relay
outputs of the controller:
Î
Connect the brown line to the relay output terminal.
Î
Connect the blue line to the terminal with the neutral con-
ductor.
We recommend fusing the individual devices. The cable section
should correspond to the validlocal regulations at 230 V~ oper-
ating voltage.
When several valves with actuators are used in one system, the
voltages must be in-phase.
Note
During routing of the cable, the connection cable must
not touch hot system components (e.g. radiator, pipes,
etc.)
After the cables have been connected to the controller or
thermostat, the actuator is ready for operation.
