EM24 DIN
Self supplied version AV9 models
“XX” and “O2” options
only: -20% +15%, 48-
62Hz. “R2”, “M1” 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.
Auxiliary power supply AV5-AV6 modules:
L: 18 to 60VAC/DC;
D: 115VAC/230VAC
