1)
the respective manufacturer is imprinted at the terminal (see section 1.2.4.1, Screw Terminal Types)
2)
plastic-insulated copper conductors (7 leads) with shield; up to 0.1 m (for side-by-side plugged
AI-8510 and CM-8820) single wires without shield are possible
Nominal voltage U
0
/U = 300/500 V, Temperature range -40…80°C
Note
For USA and Canada:
NRTL/SCC certified current transformers are required. Use only UL listed energy-
monitoring current transformers
.
Note
For each installed AI
-8510 a CM-8820 must be connected ahead, if the current measurement is used.
Thereby CM
-8820 modules may only be installed at the end of a module line (right-most), else the i
nternal
I/O bus is interrupted.
CM
-8820 modules may also be installed at a separate DIN rail
, whereby the maximal cable length must be
considered.
