WARNING: ELECTROCUTION RISK
National Electrical Code (and/or local codes) require that you provide an appro-
priately sized branch circuit protection and lockout/tagout capability. Ensure
you comply with all local and national safety and electrical codes for the
installation and operation of the robot system.
DANGER: ELECTROCUTION RISK
ISO 10218-1, Clause 5.2.4 mandates that, during installation, you must provide
a fail-safe lockout to prevent unauthorized third parties from turning on power.
WARNING: ELECTROCUTION RISK
Viper robot systems require an isolating transformer for connection to asym-
metrical mains systems or those using an isolated (impedant) neutral. Many
parts of Europe use an impedant neutral.
DANGER: ELECTROCUTION RISK
Only a skilled and instructed person must install AC power. Clause 5.2.4 of the
ISO 10218-1 requires that the person installing the system must use fail-safe
lockout measures to prevent unauthorized third parties from turning on power.
Refer to the Robot Safety Guide (Cat. No. I590) for more information.
NOTE: Install the robot system as a piece of equipment in a permanently-
installed system.

AC Power Diagrams

If using a three-phase power source, it must be symmetrically-earthed (with grounded neutral).
Connections called out as single-phase can be wired Line-to-Neutral or Line-to-Line.
