Self supplied version AV9 models
“XX” and “O2” options
only: -20% +15%, 48-
62Hz. “R2”, “XS” and “IS”
options only: -15% +10%,
48-62Hz.
AV2 model:
“XX”, “O2”, “IS” and “DP”
options: -15% +15%, 48-
62Hz. In case of 3-phase
system, 4-wire connection:
113 to 265V. In case of 3-
phase system, 3-wire con-
nection: 196 to 460V.
Note The instruments provided
with “IS” and “R2” options
work only if all the voltage
inputs are connected (3-
phase and neutral) if a 1-
phase connection has to
be performed the L1 and
L2 voltage inputs have to
be short circuited. The
instrument provided with
“O2” option, working in a
3-phase system with neu-
tral may work also if one or
two phases are missing.

General specifications (cont.)
Output Model Note
Open collector output “AV9” models with “O2” option
The meter works even if up to two voltages “phase
to neutral” are missing or if one voltage “phase to
phase” is missing.
Relay output “AV9” models with “R2” option
The neutral wire has always to be available. The
meter works even if “Phase 3” is missing but,
mandatorily, both “phase 1” and “Phase 2” have to
be available.

V9” models with “IS” option
Dupline port “A
V2” model with “DP” option
The meter works even if up to two voltages “phase

e missing or if one voltage “phase to
phase” is missing.
