2.5 UL Haz. Loc. certification
Products with this mark are tested by Underwriters Laboratories and listed as "indus-
trial control equipment for use in hazardous locations". This mark is valid for the USA
and Canada and simplifies the certification of your machines and manufacturing sys-
tems in this economic region.
Underwriters Laboratories (UL) per standard ANSI/ISA 12.12.01
Canadian (CSA) standard per C22.2 No. 213-16

2.5.1 General safety guidelines
APC3100 systems that are certified for use in potentially explosive atmospheres and bear the mark above are
suitable for use in Class 1, Division 2, Groups A, B, C and D or in nonexplosive atmospheres and correspond to
the following standards: UL Std. 61010-1, 3rd Edition, ANSI/ISA 12.12.01:2015, CSA Std. C22.2 No. 61010-1-12,
3rd Edition, CSA Std. C22.2 No. 213-16.
2.5.2 Mounting and installation
Devices with explosion protection are to be used as intended and are only permitted to be operated by knowledge-
able and qualified personnel according to these operating instructions and the additional information contained
in the user's manual. Operation in any other way endangers the safety and functionality of the devices and con-
nected systems. The operator is responsible for observing all applicable safety regulations, accident prevention
regulations and standards.
Devices must be installed in a suitable protective housing that can only be opened with the assistance of a tool. In
order to ensure sufficient air circulation, the specified clearance values must be observed. Usage is only permitted
in environments with pollution degree 2. The maximum ambient temperature varies depending on the individual
components being used, see section
"Temperature specifications" on page 23
The certification mark on the device must be checked before each installation or use of a device in potentially
explosive atmospheres. Additional equipment must be suitable for the site of operation. The final assembly must
be approved by the responsible local authorities. Wiring must be performed in accordance with national regulations
and the requirements of the authorities.
Devices must remain voltage-free until installation work is completed. The tightening torque for power supply ter-
minals is 0.5 Nm. Cables must be suitable for a surface temperature of 75°C. PPC3100 systems are only permitted
to be operated with 24 VDC.
Unshielded/Ungrounded cables are not permitted to be used in potentially explosive atmospheres under any cir-
cumstances. Devices must be securely connected to the potential equalization terminal. Power supply, communi-
cation and accessory cables must be secured on the device or control cabinet. Power supply, communication and
accessory cables are not permitted to exert excessive strain on connections. This must take into account possible
vibrations in the area.
2.5.3 Operation
To switch APC3100 systems on/off in a potentially explosive atmosphere, either a switch must be located outside
the potentially explosive atmosphere or a switch certified for use in potentially explosive atmospheres must be used.
Danger!
Explosion hazard: Accessories are not permitted to be connected or disconnected with voltage applied
unless the area is considered nonhazardous and is free of ignitable concentrations!
Explosion hazard: Replacing components may impair eligibility for Class I, Division 2!
