5.2.6.1 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,

5.2.6.2 Assembly and installation
Explosion-protected devices must be used as intended and are only permitted to be operated by qualified and
instructed specialists in accordance with these installation instructions and the additional information in the user's
manual. Any other operation endangers the safety and function of the devices and connected systems. The oper-
ator is responsible for compliance with applicable safety and accident prevention regulations and standards.
Devices must be installed in a suitable protective housing that can only be opened using a tool. In order to en-
sure sufficient air circulation, the specified clearances must be observed. Use only in environments with pollution
degree 2. The maximum ambient temperature varies depending on the individual components used, see section
"Temperature specifications" on page 26
.
Before any installation or use of a device in potentially explosive atmospheres, the certification mark on the device
must be checked. Additional equipment must be suitable for the place of use. Final assembly must be approved
by the responsible local authorities. Wiring must be carried out in accordance with national regulations and the
requirements of the authorities.
Devices must be disconnected from the power supply until installation work has been completed. The tightening
torque for power supply terminals 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.
Never use unshielded/ungrounded cables in potentially explosive atmospheres. Devices must be securely con-
nected to equipotential bonding. Supply, communication and accessory cables must be secured to the device or
control cabinet. Power supply, communication and accessory cables are not permitted to exert excessive strain on
connections. Possible vibrations in the environment must be taken into account.
5.2.6.3 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 when the power is
switched on unless the area is considered nonhazardous and is free of ignitable concentrations!
Explosion hazard: Replacing components may impair eligibility for Class I, Division 2!
