Installation and maintenance

The Safeball is mounted using four M5 screws or ST4.8 self-tapping screws. If necessary, the connection cables

can be taken out at the sides at the lower part of the Safeball. The two prepared outlets are provided for this

purpose.

The distance between two Safeballs (for a two-hand device) or to the edge of a table or a wall depends on how the

units are mounted. The minimum distances are given in the below sections.

NB: The Safeball can be mounted in many different ways; on a table or a machine, on a stand or wherever

ergonomically suitable. It is also possible to mount the Safeball either in a fixed position or on a flexible mount such

as a ball joint, allowing tilt and rotation for increased ergonomic support. Refer to the section Accessories below or

the product list at www.abb.com/jokabsafety for details.

Warning! Safeball must be installed with a minimum distance S to the dangerous machine movement. This

distance is calculated using the following formula for Safeball according to approving agencies and EN 13855:

S = K x T + C

Where:

S = safe distance in mm

K = hand speed, 1600 mm/s

T = total stopping time for the dangerous movement, including the relay response time in seconds

C = constant for possible encroachment while the actuators are operated.

Two-hand configuration: 0 mm

One-hand configuration: Must be calculated by installer, based on possible encroachment reach of

Warning! The minimum mounting distance must never be less than 100 mm. When mounting the Safeballs on

aluminium profiles or similar, the fixing screws must be locked in order to prevent the safety distance between two

Safeballs being easily changed.

Warning! All the safety functions must be tested before starting up the system.
