WARNING
1. Never connect safety signals to a PLC which is not a safety PLC
with the correct safety level. Failure to follow this warning could
result in serious injury or death as the safety functions could be
overridden. It is important to keep safety interface signals
separated from the normal I/O interface signals.
2. All safety-related signals are constructed redundantly (two
independent channels). Keep the two channels separate so that a
single fault cannot lead to loss of the safety function.
3. Some I/Os inside the Control Box can be configured for either
normal or safety-related I/O. Read and understand the complete
section6.4. Controller I/Oon the facing page.
WARNING
1. Make sure all equipment not rated for water exposure remain dry. If
water is allowed to enter the product, lockout-tagout all power and
then contact your local Universal Robots service provider for
assistance.
2. Only use the original cables supplied with the robot only. Do not use
the robot for applications where the cables are subject to flexing.
3. Negative connections are referred to as Ground (GND) and are
connected to the casing of the robot and the Control Box. All
mentioned GND connections are only for powering and signalling.
For PE (Protective Earth) use the M6-size screw connections
marked with earth symbols inside the Control Box. The grounding
conductor shall have at least the current rating of the highest
current in the system.
4. Use caution when installing interface cables to the robot I/O. The
metal plate in the bottom is intended for interface cables and
connectors. Remove the plate before drilling holes. Make sure that
all shavings are removed before reinstalling the plate. Remember to
use correct gland sizes.
