Electrical installation
WARNING:
Endangerment of electrical safety through not switching the
power supply off during installation and maintenance work
An electrical accident can occur during installation and maintenance work
when the power supply to the device or lines is not switched off using a power
isolating switch/circuit breaker.
Before starting the work, ensure the power supply can be switched off
using a power isolating switch/circuit breaker in accordance with DIN EN
61010.
Make sure the power isolating switch is easily accessible..
An additional separation device is mandatory when the power isolating
switch cannot be accessed or only with difficulty after installation of the
device connection.
The power supply may only be switched on again after work completion or
for test purposes by persons carrying out the work under consideration of
the valid safety regulations
WARNING:
Endangerment of electrical safety through incorrect measure-
ment of the mains line
Electrical accidents can occur when the specifications of a replacement for a
removable mains line have not been adequately observed.
When replacing a removable mains line, always observe the exact specifi-
cations in the Operating Instructions (Section Technical Data).
CAUTION:
Device damage through incorrect or non-existing grounding
It must be ensured during installation and maintenance work, that the protec-
tive grounding of the devices or lines involved is established in accordance
with EN 61010-1.
WARNING:
Health risk by voltage
Preparation of the electrical connections may only be performed by skilled
electricians who, based on their technical training and knowledge as well
as knowledge of the relevant regulations, can assess the tasks given and
recognize the hazards involved.
Do not connect the device to the voltage supply.
Let SICK Customer Service connect the electrical connection of the device.
