Mounting

4.1.3 Mutual interference of systems in close proximity

Prevent the mutual interference of systems mounted in close proximity!

If several WSU/WEU26@3 devices operate in close physical proximity, the sender beams

from one device may interfere with the receiver for another device such that the protective

function of the different WSU/WEU26@3 devices is no longer ensured and there is a hazard

for the operator. You must avoid such mounting scenarios or take appropriate measures,

e.g. by mounting non-reflective sight protection walls or by reversing the transmission

direction of a device.

4.2 Mechanical mounting

WSU26-3 and WEU26-3 are to be mounted to suit the local conditions on one of the sides

of their housing or using the mounting bracket. The mounting bracket significantly eases

alignment. The device can be operated in any position. WSU26-3 and WEU26-3 are,

however, to be mounted such that the axis of the beam emitted by the WSU26-3 is always

aligned with the axis of the WEU26-3 optics (alignment sight, see Fig. 18, page 27).

The mounting brackets are to be attached such that all fixing screws are easily accessibly

for alignment. Fig. 9 shows examples. The devices are to be attached such that it is

possible to align with the related device opposite using the alignment sight.
