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 Millennium II mounting framework must be
connected directly to the cabinet ac service ground bus. For applications in huts,
vaults, and central offices, the Millennium II mounting framework must be
connected to the system integrated ground grid.
•
Installing fuses not specified for use in controller may result in equipment damage.
Use only replacement parts listed in this manual and on the equipment drawings.
•
The telecom-type (e.g., GMT type) fuses can produce sparks during interruption or
clearing of a fault on a high energy circuit. Use only fuses provided with safety
caps for this type of circuit. Installing telecom-type fuses not equipped with safety
caps may result in injury to service personnel.
