Earth connecon - The
instrument does not need earth
connecon for correct operaon
nor for compliance with security
regulaons. Terminal 9 is not
connected to any internal circuit
and is provided only as a safe
place for earth wire.
Fuse - As requested by security regulaon 61010-1, add a protecon
fuse to the power to act as disconnecon element, easily accessible
to the operator and idened as a protecon device.

Signals up to 600 V and 200 V (AC and DC) must be connected at
terminals 1 and 4. Signals for 5 A current (AC and DC) must be
connected at terminals 3 and 4. All other signals must be connected
between terminals 2 and 4. Terminal 5 is a ‘mulfuncon’ terminal,
congurable with one of the following funcons :
• +15 Vdc excitaon voltage (Vexc) for process signals
• +5 Vdc excitaon for potenometer signals
• connecon for the Pt100 third wire compensaon
• external contact ‘EK’ funcon
To select the terminal 5 funcon, select the posion of internal
jumper ‘T’
(see secon 1.9) .

1. Open the instrument as indicated at secon 1.25 and access
the internal board.
2. Select jumpers ‘S’ for the signal range required (see secon
1.9).
3. Select jumper ‘T’ to assign to mulfuncon terminal 5 the
required funconality (see secon 1.9).
4. Close the instrument ad indicated at secon 1.25.
5. Connect the input signal and the power supply as indicated at
secons 1.4 and 1.5.
6. Enter the ‘conguraon menu’ to congure the instrument
(scaling, alarms, ...) (see secon 1.28).
