Notes
9.1 Connecting the measuring input leads
Connect the measuring input leads to terminals 4 (–)
and 9 (+).
9.2 Connecting the measuring output leads
Connect the measuring output leads A to terminals 1 (–)
and 6 (+).
Note: Take care that the amplifier’s maximum permissible
external burden R
ext
is not exceeded (see Section
6 “Technical Data”).
9.3 Connecting the power supply leads
Connect the power supply leads to terminals 5 ( –
~ ) and
10 (
+
~
).
A two-pole switch must be included in the supply connection
where facility for switching SINEAX TV 808 off is desired.
Note:
An external supply fuse with a rupture capacity
≤
20 A must be provided for DC supply voltages
> 125 V.
10. Commissioning
Switch on the measuring input and the power supply. The
green LED lights continuously after switching on.
The power supply unit must be capable of supplying
a brief current surge when switching on. The
instruments presents a low impedance at the in-
stant of switching which requires a current I
start
of…
… I
start
≥
160 mA for the version with a power
supply range of 24 – 60 V DC/AC
or
… I
start
≥
35 mA for the version with a power supply
range of 85 – 230 V DC/AC
11. Maintenance
No maintenance is required.
12. Releasing the isolating amplifier
