MULTIBETON B 50302 24V Strip Terminal Basic Instruction Manual

Scope of supply

Take off the cover.
Install the base. In case of wall mounting, fix the base to the wall with 2 screws
Ø 4 mm and corresponding dowels according to the quality of the wall. In case
of installation on a mounting bracket, use a bracket TS 35/7.5.
Make the electric connection.
Install the cover

Select and insert the fuse (only B 50302)

Depending on the fuse inserted
(included in the scope of delivery) the B 50302 can be oper

Parametrization

The control direction is set with jumper 1:
NO operation: Jumper 1 = ON
NC operation: Jumper 1 = OFF
The fixed follow-up time of 2 minutes of the pump or the
boiler can be increased by further 5, 10 or 15 minutes
using jumper 2 and 3:

Time	Jumper 2	Jumper 3
0 min	OFF	OFF
5 min	OFF	ON
10 minutes	ON	OFF
15 minutes	ON	ON

LED signalling (only B 40×02, B 20×02)

Electric connection

The voltage supply of the 24 V version must come from a safety transformer

according to EN 61558-2-6 or, for North America, from a Class II Transformer according to UL.

For the connection of the voltage supply, the cable sections must be a minimum of 0.75 mm² for 24 V or 1.5 mm² for 230 V. Depending on the voltage version of the base, it is possible to take L1 or L and L2 or N, as well as the protective conductor, from the base. If no temperature limiter is connected, the connection TB/%H must be bridged (provided for at the factory). The bridge must be removed as soon as a temperature limiter is connected. The temperature limiter must be a normally closed contact.

8 Maintenance
