3.2.4 External emergency stop connection
This 9-pin D-type connection is designed to permit connection of external emergency stop devices to the
Renishaw controller emergency stop system.
The machine manufacturer or product installer must perform a risk assessment to determine the
requirements for emergency stopping and emergency switching off.

(ISO13849-1:1999). The user’s risk assessment should therefore have determined that a category B
safety function is satisfactory.

Any additional emergency stop component that is fitted to this connector must have the following electrical
characteristics:

controlgear – Part 5-1: Control circuit devices and switching elements – Electromechanical control circuit
devices) or UL1054 (Standard for special-use switches).
NOTE: If there are no additional emergency stop devices to be added to the system, connect pins 6 and

The manufacturer of the finished machine, or the installer of the SPAlite, is responsible for ensuring that
the following test and verification procedures are performed to the appropriate standards on the complete
installation:
• Verification that the electrical equipment is in compliance with the technical documentation
• Continuity of the protective bonding circuit
• Insulation resistance tests
• Voltage tests
• Protection against residual voltages
• Functional tests, particularly those related to safety
