assembly with the aid of three fixing screws (not contained in the delivery)
4.1
Selecting the assembly location
The UE4155 bus node is a decentralised component. Select a suitable assembly location
in the immediate vicinity of the equipment on the basis of the following criteria:
close to the equipment, short distance for wiring to all components to be connected
flat assembly surface to enable the housing to be assembled without becoming
distorted
grounded assembly surface in order to ground the PROFIBUS screening
device’s diagnostic LEDs can be inspected, simple device exchange
protected in order to prevent any removal or breakage of the connecting wires by
personnel or equipment
adequately sized terminal compartment for the power supply, the SDL connecting wires
and the field connections (see chapter 10.5 “Dimensional drawing bus node UE4155”
on page 61)
with respect to vibrational and impact load, temperature and humidity, suitable in
accordance with the data in chapter 10.1 “Data sheet” on page 55
