2.3 Fundamental hazards
Follow the safety instructions listed here and the warning inform-
ation in the subsequent chapters of this manual in order to re-
duce health hazards and prevent dangerous situations.
2.3.1 Hazards due to electric current
Before commissioning the device, it must be ensured that...
● electrical work has been carried out properly and in accord-
ance with local regulations.
● Protection from electric shock is ensured
● All cables are sufficiently dimensioned and secured
When working on the opened device, there is a:
DANGER
Danger of death due to electric current!
An immediate danger of death exists in case of contact with live
parts. Damage to the insulation or individual components can
present a danger of death.
▶ Only have work on electric systems performed by specialised
electricians.
▶ Disconnect the device, check that no voltage is present and
secure against reactivation before opening the D‑ISC100.
▶ In the event of damage to the insulation, turn off the power
supply immediately and initiate repairs.
▶ Keep moisture away from live parts. This may lead to a short-
circuit.
In order to prevent hazards, only ever connect the Universal con-
trol unit D‑ISC100 to permissible supply voltages (see type
plate).
NOTICE
Damage to electronic components due to electrostatic discharge
(ESD)
Electronic components are becoming smaller and smaller and
more and more complex. Their susceptibility to damage from
electrostatic discharge is increased accordingly. Therefore:
▶ To protect the components, measures must be undertaken to
prevent electrostatic discharge during all work performed at
the open device (ESD protection).
▶ To prevent static charges building up on the human body,
service employees can for example be equipped with a per-
sonal earthing system.
