DANGER
!
Risk of injury from high pressure in the system
•Before loosening any lines and valves turn off the pressure and vent the valves
WARNING
!
Risk of injury from overhea ng of the control head.
Before accessing the inside of the F783E Ex‐ia control head, isolate any control power which may be hazardous to the
health of the operator.
Ensure the control head is safe to work on – secure the system against uninten onal ac va on
Avoid leaving live loose wires which can contact ground or each other and ini ate protec ve devices.
When commissioning and tes ng the control head, before manually opera ng the actuator ensure it is safe to do so.
Ensure opera ng the valve won't compromise personal or product safety. Keep hands clear of moving parts at all mes.
The control head can be installed in any installa on posi on. Ensure there is sufficient height above the control head to
remove the cap and adjust the switches.
The device should be installed such that layers of dust thicker than 5 mm cannot form; meaning that such should
be ensured through correspondingly regular cleaning.
Risk of injury from improper assembly!
Do not improperly stress the control head.
Do not apply any leverage effect on the head and do not climb on it.
For the installa on of the F783E Ex‐ia control head to a linear‐type actuator, you will require an actuator‐specific target. Be
sure to order the correct target for that actuator.
For installa on of the F783E Ex‐ia control head on a rotary‐type actuator, the target will always be the same. Depending on
the type and brand of actuator an adaptor kit may be required.

Maximum supply cable length is to be 30m. Control top must be installed in the same building as the control cabinet.
Installa on environment and wiring are influen al on the module's EMC: Thus the installer must secure EMC of the
whole device.
According to Norm EN 61326‐1: 2006 (chart 2) DC supply connec ons to the module are treated as input/output
signal lines. For cable lengths greater than 30 m and outdoor applica ons addi onal measures must be implemented
