•
All input and output connections comply with SELV requirements.
•
Insulation on field-wired conductors should be rated no less than 90° Celsius. Size
conductors based on listed recommendations. Wiring internal to enclosed
equipment cabinets should be rated at 105° Celsius (minimum).
•
Torque or secure electrical connections to the values specified on labels or in the
product documentation.
•
Alarm contacts on the office alarm connector are not fused within the controller;
therefore, current limiting protection for these contacts must be provided by
external circuits. Maximum ratings for alarm connections are 60Vdc and 0.5
amperes. Exceeding these maximum ratings could result in fire or damage to the
unit.
•
In enclosed equipment cabinets, the chassis must be connected directly to the
cabinet ac service ground bus. For applications in huts, vaults, and central offices,
the chassis must be connected to the system integrated ground grid.
•
This product operates equally well if installed as part of the Isolated Ground
Plane (Isolated Bonding Network) or the Integrated Ground Plane (Mesh-
Bonding Network, aka, Common Bonding Network). Lineage recognizes there are
different grounding techniques that are equally successful. Adhere to a
commonly accepted and consistent grounding approach to ensure personnel
safety, network protection, and proper equipment operation. Multiple low
impedance paths to Earth ground are essential.
•
The equipment and subassembly ports are suitable for connection to intra-
building or unexposed wiring or cabling. The equipment and subassembly ports
can be connected to shielded intra-building cabling grounded at both ends.
