Electric voltage!
Operate the 767 Series components exclusively with 24 VDC PELV (Protective
Extra Low Voltage) or SELV (Safety Extra Low Voltage) voltage sources. Failure
to comply may result in electric shock.

Hot connection sockets!
Even when taking into account derating, high surface temperatures on the metallic
connection sockets and on the enclosure can arise during operation. If the 767
Series component has been in operation, allow it to cool off before moving it.

The highest current carrying capacity of the supply contacts is 4 A!
Always observe the maximum current carrying capacity per supply line (U
LS
, U
A
)
for each 767 Series component and the overall power consumption for all
767 components. Neither of these values shall exceed 4 A since an increase in
current causes the contacts to overheat and damages the 767 Series components.
Information regarding the power demand of each 767 Series component can be
found in the corresponding data sheet, which is available from
www.wago.com
.

Exposed connections!
If connections have not been closed with protective caps, liquid or dirt can
penetrate the components of the 767 Series module and ruin it. Therefore, close
all unnecessary connections with protective caps, which must be ordered
separately, in order to maintain the IP67 degree of protection. (See section
“Accessories” of the fieldbus coupler/controller manual.)

•
Disconnect the power supply from the system on which you wish to mount
the 767 Series device.
•
Observe the appropriate accident prevention regulations for your system
during assembly, start-up, maintenance, and repairs. For example, BGV A3,
“Electrical systems and equipment”.
•
The operating instructions for the 767 Series module and the system
description must be laid out ready on site.
•
Observe the exact positioning (coding) between plug and socket.
•
The 767 Series device shall not come into contact with substances having
seeping and insulating properties. Otherwise, additional measures shall be
