2.1.9 Hazardous Applications
Always combine standard process I/O boards and I/O units with barriers for ex-environment in
an application-adapted way. You may use any of the available barriers on the market which meet
your requirements. However, certain barrier brands provide rational connection facilities
adapted to the Advant Controller 400 Series thus making these brands especially advisable.
The weighing board type DSXW 111 is an exception. It is intended for use in an explosive
environment.
2.1.10 High Voltage Switch-gear Applications
Normally, Advant OCS equipment is not designed for direct connection to high-voltage
switchgear. You use intermediate relays for digital input and output signals as a connecting link.
For analog signals, use special measured value converters tested in accordance with Swedish
standard SS 436 15 03 class 4.
2.1.11 Lightning Stroke Protection
Industrial installations and power plants are normally provided with well-integrated grounding
nets installed together with the power distribution system. In installations with such grounding
systems, it is not necessary to install lightning stroke protection unless you are using overhead
wiring or suspended cables outdoors.
Large dispersed plants (water supply installations, refineries, and so on) can, however, have an
inadequate grounding system and signal cables can be routed above ground. In such cases,
lightning stroke protection must be used.
Cables outside the grounding system (even for short distances such as 10 m) always require
lightning stroke protection.
For installation rules, see the general document Interference-free Electronics Design and
Applications.
2.1.12 Weight and Mounting Dimensions
When placing a control cabinet, you must provide a number of minimum distances from the
cabinet to walls and the ceiling in order to ensure satisfactory results. These minimum distances
are indicated below.
When cabinets are located next to each other, you can omit from the cabinets the wall cladding
on the sides in contact, except from a cabinet which contains equipment which generates any
