Notes on the electrical installation
NOTICE
Equipment damage or unpredictable operation due to working with live parts.
Working with live parts may result in unpredictable operation.
■
Only carry out wiring work when the power is off.
■
Only connect and disconnect electrical connections when the power is off.
■
The electrical installation must only be performed by electrically qualified person‐
nel.
■
Standard safety requirements must be met when working on electrical systems.
■
Only switch on the supply voltage for the device when the connection tasks have
been completed and the wiring has been thoroughly checked.
■
When using extension cables with open ends, ensure that bare wire ends do not
come into contact with each other (risk of short-circuit when supply voltage is
switched on!). Wires must be appropriately insulated from each other.
■
Wire cross-sections in the supply cable from the customer's power system must be
selected in accordance with the applicable standards. When this is being done in
Germany, observe the following standards: DIN VDE 0100 (Part 430) and DIN VDE
0298 (Part 4) and/or DIN VDE 0891 (Part 1).
■
Circuits connected to the device must be designed as SELV circuits (SELV = Safety
Extra Low Voltage).
■
Protect the device with a separate fuse (type-specific max. 2 A (unheated) or 3 A
(heated)) at the start of the supply circuit.
NOTE
Layout of data cables
■
Use screened data cables with twisted-pair wires.
■
Implement the screening design correctly and completely.
■
To avoid interference, e.g. from switching power supplies, motors, clocked drives,
and contactors, always use cables and layouts that are suitable for EMC.
■
Do not lay cables over long distances in parallel with power supply cables and
motor cables in cable channels.
The specified IP enclosure rating for the device is only achieved under the following con‐
ditions:
■
The cables plugged into the connections are screwed tight.
■
Any electrical M12 connections that are not being used must be fitted with tightly-
fastened protective caps or plugs (as in the delivery condition), depending on the
type.
■
Any other possible coverings must be closed and lie flush on the device.
In the event of non-compliance, the IP enclosure rating will not apply for the device.
Additional notes on devices with integrated heating
When using heated devices, the following additional points must be noted:
■
Use cables suitable for the environmental conditions. In case of doubt, consult
SICK Service.
■
Only operate in idle state (no mounting or connection work).
