Installation
3.2 Electrical installation
N O T I C E
Protect the instrument from extreme temperatures from heaters, direct sunlight and other heat
sources.
WA R N I N G
Electrical and fire hazards. Use only the supplied power cable.
Only qualified experts may perform the tasks described in this section of the manual, while
adhering to all locally valid safety regulations.
N O T I C E
Use only earthed sockets for the connection of this device to the power supply.
If you are not sure if the sockets are earthed, have this checked by a qualified electrician.
The power plug serves in addition to the power supply to isolate the device quickly from the
mains where necessary.
The entire measurement system has two power plugs (measurement device and open loop
control unit).
During the disconnection from the power source it must be made sure that the correct power plug
is pulled (for example by labeling the sockets).
This is recommended for long-term storage and can prevent potential dangers in the event of a
fault.
Therefore make sure that the sockets to which the device is connected are easy to reach by each
user at all times.
N O T I C E
Pull out power plug before the opening of the device.
3.2.1 Connect the pipe trace heater and fault indication contact
WA R N I N G
The electrical connection for the pipe trace heater must be carried out by a specialist electrician.
N O T I C E
If the mains plug·of the power connection cable·is removed and replaced by hard wiring, then in
immediate proximity of the display unit a suitable double-pole one-way circuit breaker with clear
labeling for the power supply must be installed.
All connected signal connection lines must be shielded.
