Analog Output
WARNING WARNING WARNING WARNING
There may be up to 200 V isolation potential between analog common and earth (CE
version) or up to 500 V isolation potential (Standard version). Avoid contact with
analog output terminals and the cables connected to them. Do not apply power until
after the AC line and analog output connections have been properly made. The AC
line must remain connected to the unit whenever the analog output terminals are
connected to a device exceeding 60 VDC or 30 Vrms common mode voltage. Contact
with voltage potentials could cause bodily injury or death!
CAUTION CAUTION CAUTION CAUTION
Solid wire is recommended for the analog output terminal connections. If stranded
wire is used, then strip the wire 6 mm, and twist or tin the stripped end. After
tightening the connector, check that no loose wire strands are present.
Terminal Installation Category: Standard: Not Applicable. CE: Category 1.
