3 SAFETY PRECAUTIONS
DANGER!
Hazard due to electrical voltage in the system!
Working on the unit involves acute risk of injury.
• Before starting work, be sure to switch off the supply voltage and
secure it to prevent restarting!
• Observe all applicable accident prevention and safety regulations for
electrical equipment!
Danger from using the Power I/O Box Type 8643 in unauthorized
ambient temperature ranges!
Hazardous situations may arise due to use in unauthorized ambient tem-
perature ranges, especially in potentially explosive environments.
• Remain within the appropriate ambient temperature range, for each
type (e. g. 8643-4-AL-KS-F-I/O), according to the table in the EC-Type
Examination Certificate.
Hazard due to unauthorized combination of types of ignition protec-
tion!
Hazardous situations may arise due to unauthorized combination of differ-
ent types of ignition protection!
• Once the bus supply has been used in an increased ignition protection
class (e), the bus supply may no longer be done at the intrinsical stand-
ard ignition protection class (i).
WARNING!
Unintentional operations or unauthorized tampering can lead to gen-
erally dangerous situations including personal injury.
• Take suitable measures to prevent unintentional operation or unauthor-
ized tampering!
Dangerous situations may occur during installation and maintenance

CAUTION!
Electrostatically sensitive components / modules
The system contains electronic components that react sensitively to elec-
trostatic discharge (ESD).
Contact with electrostatically charged persons or objects can endanger
these components. In the worst case they may be immediately destroyed or
fail after commissioning.
• Observe the requirements of EN 100 015 - 1 in order to avoid or mini-
mize the risk of damage caused by sudden electrostatic discharges.
• Pay attention not to touch electronic components when the supply volt-
age is switched on.
NOTE!
• The Power I/O Box Type 8643 has been developed in compliance with
recognized technical safety regulations and represents state-of-the-art
technology. However, dangers may nevertheless arise.
• Operate the Power I/O Box Type 8643 only when it is in proper working
order and only in accordance with the operating manual.
• Do not subject the housing of the Power I/O Box Type 8643 to mecha-
nical loads (e. g. by using it as a support for objects or as a step).
• Failure to observe this operating manual and its operating instructions
as well as unauthorized tampering with the device release us from any
liability and also invalidate the warranty covering the devices and acces-
sories!
• The Ex approval is only valid if the Power I/O Box Type 8643 is used

5 SYSTEM DESCRIPTION
5.1 General Description
The Power I/O Box Type 8643 with FOUNDATION Fieldbus activation
(hereafter Power I/O Box Type 8643) is used for the activation of binary
signals on the FOUNDATION Fieldbus.
It is suitable for use in potentially explosive atmospheres and has been ap-
proved according to ATEX for use in Zone 1 and 21.
This device is supplied in either an aluminum or polyester housing in protec-
tion class IP65 or as an electronic module in protection class IP20/IP30 for
installation in housings with Ex-e approval or control cabinets.
All cable fittings are found on the bottom.
The device is supplied via a separate power supply source for the Ex-i bus
due to the fact that the usable energy from the bus wiring is extremely lim-
ited.
