Electrical Requirements
B.5.1
Site wiring and Power Requirements
Each enclosure has two power supply modules for redundancy. If full redundancy is
required, use a separate power source for each module. The AC power supply unit in each
power supply module is auto-ranging and is automatically configured to an input voltage
range from 88–264 VAC with an input frequency of 47–63 Hz. The power supply modules
meet standard voltage requirements for both U.S. and international operation. The power
supply modules use standard industrial wiring with line-to-neutral or line-to-line power
connections.
B.5.2
Power Cable Requirements
Each enclosure is shipped with two power cables designed for use with the enclosure power
supply module. Each power cable connects one of the power supply modules to an
independent, external power source. To ensure power redundancy, connect the two power
cables to two separate circuits; for example, to one commercial circuit and one
uninterruptible power source (UPS).
B.6
Management Host Requirements
A local management host with at least one mini-USB connection is recommended for the
initial installation and configuration of a controller enclosure. After you configure one or
both of the controller modules with an IP address, you then use a remote management host
on an Ethernet network to manage and monitor.
NOTE:
Connections to this device must be made with shielded cables – grounded
at both ends – with metallic RFI/EMI connector hoods, in order to maintain
compliance with FCC Rules and Regulations.
