Mounting instruction see www.metz-connect.com
• The module can be aligned without interspace. Use the jumper
plug to connect bus and supply voltage when the modules are
mounted in series.
• The maximum quantity of modules connected in line is limited
to 15 or to a maximum power consumption of 2 Amps (AC or
DC) per connection to the power supply. For any similar block of
additional modules a separate connection to the power supply is
mandatory.
Preparing cable for connection.
Strip the wire by 7 mm, attach an end sleeveif necessary, insert
the wire into the contact and tighten the terminal screw with a
screwdriver.
