4.4 Installing Electrically

The T-Guard requires a 24 V DC power supply (tolerance ± 10 %).

A wrong polarity triggers the fuse.

The power supply should be able to supply a current of maximum 6 A. Typically, the

T-Guard needs 70W.

The following maximum cable lengths have to be met:

Notice Do not power up the power supply before having attached all other cables

you need!

Power Connector

Only two of the four pins are used for the power supply. The plus pole is marked with

„1+“, the minus pole is marked with „2-“.

4.5 Connecting the control unit

Attach one end of the control unit cable to the connector CONTROL UNIT of the T-

Guard™ Leak Detection Sensor and the other end to the control unit itself. Now T-

Guard™ Leak Detection Sensor can be operated via the control unit.
