Installation and connection of the multimeter should be
carried out by the qualified personnel. All available pro-
tection requirements must be taken into account.
Power supply voltage.
The DMM-5T-2 Multimeter is po-
wered via the V1, V2, V3, N voltage terminals and does
not require an auxiliary power supply. It is recommen-
ded to protect the power supply and voltage circuits of
the meter with a 1 A fuse-link.
Measuring voltage.
The maximum value of the me-
asuring voltage must not exceed 280 V AC (phase voltage
between the L-N terminals) or 500 V AC (phase voltage
between the L-L terminals). Exceeding the maximum va-
lue of the measuring voltage may damage the device.
Measuring current.
The multimeter is designed for in-
direct current measurement using current transformers
with a 5 A secondary current. If the measuring current
exceeds 6 A, it may damage the device.
