Prerequisites for the safe operation of the device in a system
WARNING
Risk of injury and damage due to electrical current!
Incorrect grounding of the device can result in equipotential bonding currents between
the device and other grounded devices in the system. This can lead to the following
dangers and faults:
•
Hazardous voltages are applied to the metal housings.
•
Devices will malfunction or sustain irrepairable damage.
•
Cable shieldings are damaged by overheating and cause cable fires.
Remedial measures:
•
Only qualified electricians should be permitted to carry out work on the electrical
system.
•
Install the grounding for the sensor and the system in accordance with national
and regional regulations.
•
Ensure that the ground potential is the same at all grounding points.
•
If the cable insulation is damaged, disconnect the voltage supply immediately and
have the damage repaired.
Observe the following safety measures:
■
Only skilled electricians with appropriate training and qualifications are permitted
to perform electrical installation.
■
Standard safety requirements must be met when working in electrical systems.
■
Electrical connections between the TriSpector1000 and other devices may only be
made or disconnected when there is no power to the system. Otherwise, the
devices may be damaged.
■
Where connecting cables with one end open are concerned, make sure that bare
wire ends do not touch each other (risk of short circuit when the supply voltage is
switched on). Wires must be appropriately insulated from each other.
■
Wire cross sections of the supply cable from the customer's power system should
be designed and protected in accordance with the applicable standards.
■
If the supply voltage for the TriSpector1000 is not supplied via the CDB650-204
connection module, the TriSpector1000 must be protected by a separate slow-
blow fuse with a max. rating of 2.0 A. This fuse must be located at the start of the
supply circuit.
■
All circuits connected to the TriSpector1000 must be designed as SELV circuits
(SELV = Safety Extra Low Voltage).
