4.2.3 Railing Installation
Disconnect the DCV controller power before performing adjustments to surrounding devices. Confirm
that the robot arm has stopped operating completely before performing adjustments according to EN
ISO 13857 (EN294&EN811) Safety Distance for Upper and Lower Limbs.
You must consider the operating range of the robot arm height in setting the height of the railings, as
well as the distance to worker contact and the time for the robot arm to stop moving after the power has
been disconnected. Figure 4.5 shows the recommended installation distance for operating the DRV70L
robot arm in full stroke (when the railing height is 2 m). Table 3.1 lists the installation distances between
the robot and the railings.
a: Height of hazard zone
b: Height of robot
c: Height of protective structure
d: Horizontal safely distance to hazard zone
H : Vertical safety distance
