Specifications
Note: TiDL (EtherCAT) technology is no longer offered in the SEL-487E-3, -4.
TiDL (T-Protocol) is available in the SEL-487E-5. If the relay is using a
TiDL (EtherCAT) system, such as TiDL, the operating times will be delayed
by 1.5 ms. Use caution when setting the relay coordination times to account
for this added delay. Element operate times will also have this small added
delay.
Compliance
Designed and manufactured under an ISO 9001 certified quality
management system
FCC Compliance Statement
This equipment has been tested and found to comply with the limits for
a Class A digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference in which case the
user will be required to correct the interference at his own expense.
