alarm relay only accommodate one cable. Route the signal from the alarm relay to a terminal on the

distributor block. The block's terminals are all interconnected. You therefore have 3 additional terminals on

this block from where you can carry the signal forward to the consumer (siren, lamp etc.). The signal can

be multiplied in this way.

6.2 Connecting the measuring device

LWARNING

Device is live!

Incorrect connection may result in injury or death!

‣The electrical connection may be performed only by an electrical technician.

‣The electrical technician must have read and understood these Operating Instructions

and must follow the instructions contained therein.

‣Prior to commencing connection work, ensure that no voltage is present on any cable.

NOTICE

The device does not have a power switch!

‣Provide a protected circuit breaker in the vicinity of the device at the place of

installation.

‣The circuit breaker must be a switch or power switch, and must be labeled as the circuit

breaker for the device.

‣At the supply point, the power supply must be isolated from dangerous live cables by

double or reinforced insulation in the case of devices with a 24 V supply voltage.

6.2.1 Opening the housing

NOTICE

Pointed or sharp tools

The use of unsuitable tools can cause scratches on the housing or damage to the seal, and

therefore negatively affect the leak-tightness of the housing!

‣Do not use any sharp or pointed objects, e.g. a knife, to open the housing.

‣Only use a suitable Phillips screwdriver.
