The
instrument does not need earth
connection for correct operation
nor for compliance with security
regulations. 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 regulation 61010-1, add a protection
fuse to the power to act as disconnection element, easily accessible
to the operator and identified as a protection 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 ‘multifunction’ terminal,
configurable with one of the following functions :
• +15 Vdc excitation voltage (Vexc) for process signals
• +5 Vdc excitation for potentiometer signals
• connection for the Pt100 third wire compensation
• external contact ‘EK’ function
To select the terminal 5 function, select the position of internal
jumper ‘T’ (see section 1.9).
