5.2 Connecting the device
LWARNING
Danger! Electric voltage!
‣The entire connection of the device must take place while the device is de-energized.
5.2.1 Connecting the power supply
• Before wiring the device, ensure that the supply voltage corresponds to the specification
on the nameplate.
• For the 90 to 250 VAC (power supply connection) version, a switch marked as a
separator, as well as an overvoltage organ (rated current ≤10 A), must be fitted in the
supply line near the device (easy to reach).

6.3.3 Disabling the programming mode
User code
The configuration can be protected against unintentional access by means of a four-digit
code. This code is defined in menu item 55 "Parameter/user code". All the parameters
remain visible but can only be changed after entering the user code.The "key" symbol is
shown on the display.
If the limit values are also to be locked, the "Limit code" must be set to "On" in menu item
55. Limit values can then only be changed after entering the user code. If the limit code is
set to "Off", limit values can be changed without entering the user code. All the other
parameters are locked, however.
Hardware locking
In addition, configuration can also be locked using a connector on the rear of the device
(→  12,  19). This is indicated by the "padlock" symbol on the display.
To hardware-lock the measuring device, insert the jumper into position J1 in the top
righthand corner on the rear of the device.

Make sure that all post-connection checks have been carried out before you commission
your device:
Checklist connection check →  14
Remove the protective strip from the display as this restricts display legibility
otherwise.
7.2 Switching on the measuring device
Once the operating voltage is applied, the green LED indicates that the device is
operational.
• When the unit is delivered, the device parameters are used as per the factory settings.
• When commissioning a device already configured or preset, measuring is immediately
started as per the settings. The limit values only switch once the first measured value
has been determined.
• The limit values are only activated as per their configuration once a valid measured value
is present.
7.3 Device configuration
This section describes all the configurable instrument parameters with the associated
value ranges and factory settings (default values, marked in bold).
