5.3 Electrical connection

The electrical connection must only be made by qualified skilled
■
personnel.
Connection details and switching functions are given on the
■
connection diagram. Connection terminals are appropriately marked.
Seal the cable bushing  at the connection housing  (see
■
illustration in chapter 5.2 "Mounting").
The mains connection lines to be provided must be dimensioned
■
for maximum instrument current supply and comply with IEC 227 or
IEC 245.
WARNING!
Electrical connection errors of the float switches can destroy
the reed contacts. This can lead to a malfunction in the plant
and thus lead to injury to personnel or damage to equipment.
▶
No direct operation in circuits with inductive loads.
▶
No direct operation in circuits with capacitive loads, e.g.
PLC, PCS or cable lengths > 50 m.
▶
Do not exceed the permissible switching power.
DANGER!
Physical injuries
With float switches with connection cable without protective
conductor connection, it is possible for the switch to become
live in the event of a malfunction. Any contact can result in
physical or even fatal injury.
▶
Only operate these switches at safety extra-low voltage
in accordance with VDE0100 or fit them so that the float
switch is electrically connected to the equipotential
bonding.
