Mounting requirements
This instrument is intended for permanent installa-
tion, for indoor use only, in an electrical panel which
encloses the rear housing, exposed terminals and
wiring on the back. Select a mounting location having
the following characteristics:
1. It should be easily accessible;
2. There is minimum vibrations and no impact;
3. There are no corrosive gases;
4. There are no water or other fluids (i.e. condensation);
5. The ambient temperature is in accordance with the
operative temperature (0... 50°c);
6. The relative humidity is in accordance with the
instrument specifications (20... 85%);
The instrument can be mounted on panel with a
maximum thickness of 15 mm.
When the maximum front protection (IP65) is desired,
the optional gasket must be mounted.

Note: Terminal 4 can be programmed as:
- digital Input (dI2) connecting a free of voltage
contact between terminals 4 and 16;
- 0... 12 V SSr drive Output (OP4) connecting the load
between terminals 4 and 16;
- 12 Vdc (20 ma) transmitter power supply connect-
ing the 2 wire transmitter between terminals 4
and 1; for 3 wire transmitter connect terminal
4 to transmitter power supply input and termi-
nal 1 and 2 to transmitter signal output.

eLKM43 servodrive models both Out2 and Out3
are to be selected as “M” in configuration code;
Out2: open, Out3: close.
General notes about wiring
1. Safety regulations require a line switch marked as
instrument disconnecting device. This switch must
be easily reachable by the operator;
2. do not run input wires together with power cables;
3. external components (like zener barriers, etc.) con-
nected between sensor and input terminals may cause
errors in measurement due to excessive and/or not
balanced line resistance or possible leakage currents;
4. When a shielded cable is used, it should be con-
nected at one point only;
5. Pay attention to the line resistance, a high line
resistance may cause measurement errors.
6. To avoid electrical shocks, connect power line at last;
7. Before connecting the instrument to the power
line, make sure that line voltage is equal to the
voltage shown on the identification label;
8. The power supply input is NOT fuse protected.
Please, provide an external fuse T type 1a, 250 V.
