WARNING: ELECTRICITY
Failure to follow any of the below can result in serious injury or death due to
electrical hazards.
•
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.
•
Only use the original cables supplied with the robot only. Do not use the
robot for applications where the cables are subject to flexing.
•
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.
CAUTION
Disturbing signals with levels higher than those defined in the specific IEC
standards can cause unexpected behaviors from the robot. Be aware of the
following:
•
The robot has been tested according to international IEC standards for
ElectroMagnetic Compatibility (EMC). Very high signal levels or
excessive exposure can damage the robot permanently. EMC problems
are found to happen usually in welding processes and are normally
prompted by error messages in the log. Universal Robots cannot be held
responsible for any damages caused by EMC problems.
•
I/O cables going from the Control Box to other machinery and factory
equipment may not be longer than 30m, unless additional tests are
performed.
GROUND
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.
READ MANUAL
Some I/Os inside the Control Box can be configured for either normal or safety-
related I/O. Read and understand the complete Electrical Interface chapter.
