UL notice - Compact Motion

NOTICE

Application

Beckhoff EtherCAT modules are intended for use with Beckhoff’s UL Listed EtherCAT System only.

NOTICE

Examination

For cULus examination, the Beckhoff I/O System has only been investigated for risk of fire and electrical shock (in accordance with UL508 and CSA C22.2 No. 142).

NOTICE

For devices with Ethernet connectors

Not for connection to telecommunication circuits.

NOTICE

Notes on motion devices

Motor overtemperature
Motor overtemperature sensing is not provided by the drive.
Application for compact motion devices
The modules are intended for use only within Beckhoff’s Programmable Controller system Listed in File E172151.
Galvanic isolation from the supply
The modules are intended for operation within circuits not connected directly to the supply mains (galvanically isolated from the supply, i.e. on transformer secondary).
Requirement for environmental conditions
For use in Pollution Degree 2 Environment only.

Basic principles

UL certification according to UL508. Devices with this kind of certification are marked by this sign:

Application

If terminals certified with restrictions are used, then the current consumption at 24 V_DC must be limited accordingly by means of supply

from an isolated source protected by a fuse of max. 4 A (according to UL248) or
from a voltage supply complying with NEC class 2.
A voltage source complying with NEC class 2 may not be connected in series or parallel with another NEC class 2compliant voltage supply!

These requirements apply to the supply of all EtherCAT bus couplers, power adaptor terminals, Bus Terminals and their power contacts.
