Follow the instructions as stated under the previous heading 'General'.
The signal light with cable gland & terminals is suitable for wall-mounting by using the bracket. It is also
suitable for assembly using a pipe clamp across the cylindrical part (D=60) of the housing. In that case,
remove the mounting bracket and reverse the cover of the connection compartment along with its
cover screws.
Ensure that the cable gland fits the individual cable used with respect to clamping size and type of
cable. If not, apply a suitable cable gland and make sure that it is approved for its application.
Connect an external earth wire to the earth boss and make sure that it is sufficiently connected to
ground.
The electrical power supply must be connected to (L) and (N) terminals in the connection
compartment. If a direct current power supply is used, reverse polarity of the power supply will not
affect the function or the safety of the signal light.
Additionally, an earth wire must be connected to the PE connection terminal, see the wiring diagram
below.
Remove the external insulation from the cable over a length of 150 mm.
Feed the cable into the connection compartment and fix the cable gland into place.
Connect the connection wires following the instructions as given in this manual in chapter (14)

For the 4-pole model (linking function), a 16
