DANGER
Danger fatal injury caused by electric shock
External voltages may still be connected even if
the operating voltage is switched off.
Possible consequence: fatal or serious injury.
• All electrical work must be performed by a
qualified electrician.
• The Electronics module is not equipped with a
mains switch and is in operation as soon as
the supply voltage is applied. An external
switch or circuit breaker with a clearly identifi-
able “Off” switch position is necessary.
• The Electronics module may only be operated
with the prescribed supply and control voltage
(technical data).
• In the event of a fault in the electrical power
supply, switch the device off immediately.
• Do not carry out work on active parts and equip-
ment to which voltage is applied.
• The device operates with liquids. For this rea-
son, DIN EN IEC 62368/60950 must be
observed when connecting the devices.
WARNING
Danger caused by uncontrolled dosing and
incorrect circulation output
If there is a shortage of sample water or the flow
rate is too low, if the circulation is switched off or
the circulation output is too low, there is a risk of
uncontrolled dosing of chemicals.
Possible consequence: fatal or serious injury.
• Never disable the sample water monitoring -
even temporarily, e.g. by bridging the signal
input.
• Chemical dosing must switch off if the circula-
tion is switched off or if the circulation output or
flow rate is too low. To ensure this, circulation
output or flow rate monitoring must be installed
in the system and connected to the electronic
module.
WARNING
Risk of injury due to chemicals
Dosing liquids are caustic and oxidizing.
Possible consequence: fatal or serious injury.
• Observe safety regulations and the prescribed
protective clothing for handling chemicals.
• All instructions in the product data sheet for the
dosing medium must be complied with.
