Note on the swivel connector
NOTICE
Damage to the connector unit from over tightening!
The connector unit on the device has two opposite end positions.
■
Do not rotate the connector unit from either of the two end positions by more than
180°.
■
Always rotate the connector unit in the direction of the display LEDs.

Prerequisites for the safe operation of the device in a system
WARNING
Risk of injury and damage caused by electrical current!
As a result of equipotential bonding currents between the device and other grounded
devices in the system, faulty grounding of the device can give rise to the following dan‐
gers and faults:
■
Metal housings are vulnerable to dangerous voltage.
■
Devices will behave incorrectly wrongly or be destroyed.
■
Cable shielding will be damaged by overheating and cause cable fires.
Remedial measures
b
Only skilled electricians should be permitted to carry out work on the electrical sys‐
tem.
b
Ensure that the ground potential is the same at all grounding points.
b
If the cable insulation is damaged, disconnect the power supply immediately and
have the damage repaired.
b
Where local conditions are unfavorable and thus do not meet conditions for a safe
earthing method (same ground potential at all grounding points), take measures in
accordance with the following formats.
The device is designed and tested for electrical safety in accordance with EN 60950-1.
It is connected to the peripheral devices (power supply, any local clock reading pulse
sensor(s), PLC) via shielded cables. The cable shield – for the data cable, for example –
rests against the metal housing of the device. The device can either be grounded
through the cable shield or through one of the threaded mounting holes.
If the peripheral devices have metal housings and if the cable shields also lie on their
housings, it is assumed that all devices involved in the installation have the
same
ground potential
.
This is achieved by complying with the following conditions, for example:
