Chapter 4: System Installation Specifications for AC Power Table 4-4. Specifications for 200-240 VAC User-Supplied Power Supply NOTE: The Hornet 565 robot is intended to be installed as a piece of equipment in a permanently-installed system. NOTE: If a three-phase power source is used, it must be symmetrically-earthed (with grounded neutral). Connections called out as single-phase can be wired Line- to-Neutral or Line-to-Line. WARNING: Hornet 565 systems require an isolating trans- former for connection to mains systems that are asym- metrical or use an isolated (impedant) neutral. Many parts of Europe use an impedant neutral. DANGER:
AC power installation must be performed by a skilled and instructed person - see the Robot Safety Guide . During installation, unauthorized third parties must be pre- vented, through the use of fail-safe lockout measures, from turning on power. This is mandated by Clause 5.2.4 of the ISO 10218-1. Failure to use appropriate power (less than or more than the rated voltage range of 200-240 VAC) can lead to mal- function or failures of the robot or hazardous situations. Facility Overvoltage Protection The robot must be protected from excessive overvoltages and voltage spikes.
If the country of installation requires a CE-certified installation or compliance with IEC 1131-2, the following information may be helpful. IEC 1131-2 requires that the installation must ensure that Category II overvoltages (i.e., line spikes not directly due to lightning strikes) are not exceeded. Transient overvoltages at the point of connection to the power source shall be controlled not to exceed overvoltage Category II, i.e., not higher than the impulse voltage corresponding to the rated voltage for the basic insulation. The user-supplied equipment or transient suppressor shall be capable of absorbing the energy in the transient.
In the industrial environment, non-periodic overvoltage peaks may appear on mains power supply lines as a result of power interruptions to high-energy equipment (such as a blown fuse on one branch in a 3-phase system). This will cause high current pulses at relatively low Hornet 565 Robot User's Guide, 14608-000 Rev C Page 50 of 156 Auto-Ranging Nominal Voltage Minimum Operating Voltagea Maximum Operating Voltage Frequency/ Phasing External Circuit Breaker, User-Supplied 200 to 240 V 180 V 264 V 50/60 Hz 1-phase 10 Amps aSpecifications are established at nominal line voltage.
