lectrical connection

Electrical connection can only be made in a voltage - free state!

In the event that the level meter (sensor) is installed in an outdoor environment at a distance

greater than 20 m from the outdoor switchboard, or from an enclosed building, it is necessary

to supplement the electrical cable leading to the level meater (sensor) with suitable overvoltage

protection.

In the event of strong ambient electromagnetic interference, paralleling of conductors with power

distribution, or for distribution to distances over 30 m, we recommend using a shielded cable.

The source of the power voltage must comprise of a stabilised safe low power source with

galvanic separation. In the event that a switch-mode power supply is used, it is essential

that its construction effectively suppresses common mode interference on the secondary

side. In the event that the switch-mode power supply is equipped with a PE safety terminal,

it must be unconditionally grounded!

The device may only be connected to the power supply via an easy to reach switch with marked

turned off / on positions and must be protected by a fuse or circuit breaker with a value of max. 6 A!

The switch or circuit breaker used as the disconnect device must be in accordance with the

IEC60947-1 and IEC60947-3, must be marked and must not be in the network inlet.

RFLS-53N-_-RE(SSR)-_

The output wire of the device is not separated from hazardous circuits. It must not be connected

to secondary accessible safety circuits.
