WarnIng
risk of injury and property damage due to electrical faults.
If the connections for the safety-related shut-off are not con-
nected correctly, there is a risk of injury due to uncontrolled
behaviour of the plant.
▶ When using several SIA variant valves, connect each con-
nection to an individual potential-free contact (mechanical
switch or relay). Never connect several contacts together
under any circumstances!
▶ Do not apply voltage to the connections (risk of damage to
the valves).
risk of injury due to sharp edges.
Sharp edges on the connection or on the contacts of the
screw-type terminal can cause cuts.
▶ Wear suitable protective gloves.
Type 6534 valves for safety-related shut-off (SIA variant) are
equipped with additional connection terminals. The circuit of a
valve can therefore be interrupted by an external switch. Manual
override is not required for these valve variants.
The technical data of the Type 6534 SIA variant valves corre-
sponds to the data of the standard device.
To use the shut-off function, connect the connection to a
potential-free contact (mechanical switch or relay).

Installation
Fig. 9: Connection terminals SIA variant
The yellow connection terminals are pluggable and can be
removed to facilitate connection of a cable. Except for CFH,
there are always 2 connection terminals. To avoid mixing up the
connections, the connection terminals are coded.
On delivery, the connection terminals are provided with a bridge
to ensure the valve can be put into operation immediately.
Remove the bridge before connecting a cable.
