4.2 Safety, Environmental Conditions and EMC
Approvals:
6DL3100–8AA/–8AB/–8AC has the following approvals:
S UL-Recognition-Mark: Underwriters Laboratories (UL) to Standard UL 508
S CSA-Certification-Mark: Canadian Standard Association (CSA) to Standard C
22.2 No. 142
CE Approval
6DL3 100–8AA/–8AB/–8AC fulfills the requirements of the EC guideline
89/336/EEC ”Electromagnetic compatibility” and the EC guideline 73/23/EEC
”Low–voltage guideline”.
Safety
Device standard DIN EN 61131-2 ¢ IEC 61131-2 ¢ VDE 0411, Part 500
Self–heating The overtemperature of the metal housing amounts to approx.
20 K under full load. At 60°C ambient temperature the limiting
temperature of 70°C is thus exceeded. Above this temperature
safe contact (to DIN EN 61131–2) is not possible without pro-
tection.
Power supply Only extra low voltage separated safely from the system may
be used for the 24 V DC supply.
Safe separation can be realized in accordance with the requi-
rements e.g. in VDE 0100 Part 410 ¢ HD 384-4-41 ¢
IEC 364-4-41 (as functional extra–low voltage with safety se-
paration PELV) or in VDE 0805 ¢ EN 60950 ¢ IEC 950 (as
safety extra–low voltage SELV) or in VDE 0106 Part 101.
Mounting safety requirements 6DL3100–8AA/–8AB/–8AC is an ”open device” in accordance
with DIN IEC 61131–2 and an ”open type” in accordance with
the UL/CSA certification
In order to fulfill the requirements for safe operation with regard
to mechanical strength, flame retardance, stability and shock
protection the following alternative installation types are pre-
scribed:
– Installation in a suitable cabinet
– Installation in a suitable housing
– Only permitted in accordance with DIN EN 61131–2:
Installation in a correspondingly equipped closed operating
area
Control–to–load isolation The control–to–load isolation for the areas described in Sec-
tion 4.1 is designed to 50 V in nominal operation. In the routine
test the dielectric test is carried out in accordance with UL 508
(test voltage / test duration 707 V DC / 1 min or alternatively
849 V DC / 1 s at de–activated test specimen).
Protection again foreign bodies and
water
Degree of protection IP 20 in accordance with IEC 529, i.e.
protection against contact with standard probes. There is no
protection against ingressing water.
Noise emission None
