Installation
3.1.3 Preparing the installation
DANGER
Risk of electric shock!
Plan the mechanical fastening before you position posts or
drill holes. Choose a suitable place to install the instrument.
Plan how the cables and tubing will be laid and their routes.
Note that the cables will need to be removed regularly.
Lay cables and tubing so they will not cause tripping and
without sharp bends. Note that the cables will need to be
removed regularly.
Do not connect the electrical power supply to the mains until
the instrument has been fully wired and fused.
Provide adequate fuse protection for the electrical power
supply.
Always connect a residual current circuit breaker (trigger
current max.: 30 mA) between the mains and the system!
If you install the instrument outside, provide overvoltage
protection between the mains and the system!
