1. General
1.1 Information on the intended use
•The terminal box KL 1 is intended for the professional electrical connection of 2-wire
transmitters. It offers integrated atmospheric pressure compensation. Optionally
equipped with overvoltage protection and Pt 100 transmitter for BD SENSORS de-
vices.
•The terminal box KL 1 is equipped with a pressure balance item for equalization of
atmospheric reference. Caused by this on the supply side a cable without ventilation
tube can be used.
•Vertical terminal clamps enable easy connection of cables inside. The terminal box
has to be mounting via two fastening screws.
•The device shall be used according to the area of application specified above!
•No liability is assumed and warranty claims are excluded in case of improper applica-
tion, modification or damage to the device.
1.2 Target group
This operating manual is intended for qualified technical personnel.

3. Installation
3.1 General notes
•Do not use any force when installing the device!
•Handle the terminal box carefully and properly to avoid any damages.
3.2 Installation steps
•Carefully remove the terminal box from the package.
•Mount the terminal box stationary on a suitable fixing location via two appropriated
fastening screws.
3.3 Lead in the transmitter cable
•Lead in the connecting cable of the transmitter through the cable gland on the left
side. The cable length inside the terminal box has to be long enough for connecting
the cords with the terminal clamps on the left (transmitter).
•Next tighten the cable gland by hand. Take care that the cable is strain-relieved.
•Pay attention that the PTFE-filter on the gauge reference is not damaged or removed.
3.4 Lead in the supply line
•Lead in the supply line through the cable gland on the right side. The cable length in-
side the terminal box has to be long enough for connecting the cords with the terminal
clamps on the right (supply).
•Next tighten the cable gland by hand. Take care that the cable is strain-relieved.

3.6 Option overvoltage protection
•With optionally overvoltage protection additionally a solid conductor with a minimal
cross section of 4 mm2has to be connected with the external ground clamp.
•Besides it also has to be connect with a suitable grounding (earth bus bar;
equipotential bonding)
