Safety Statements
 Do not install this equipment over combustible surfaces.
 Rules and Regulations - Follow all national and local rules and regulations when making field connections.
 Compression Connectors
 U. S. or Canada installations - use Listed/Certified compression connectors to terminate Listed/Certified field-wire conductors.
 All installations - apply the appropriate connector to the correct size conductor as specified by the connector manufacturer, using only
the connector manufacturer’s recommended or approved tooling for that connector.
 Electrical Connection Securing: Torque to the values specified on labels or in the product documentation.
 Cable Dress - dress to avoid damage to the conductors and undue stress on the connectors.
 Circuit Breakers and Fuses
 Use only those specified in the equipment ordering guide.
 Size as required by the National Electric Code (NEC) and/or local codes.
Safety Tested Limits - Refer to the equipment ratings to assure current does not exceed:
Continuous Load (List 1) - 60% of protector rating
Maximum Load (List 2 - typically end of discharge) - 80% of protector rating.
 GMT Style Fuses - Use only fuses provided with safety caps.
 Field-wired Conductors - Follow all National Electric Code (NEC) and local rules and regulations.
 Insulation rating: 90°C minimum; 105°C (minimum) if internal to enclosed equipment cabinets.
 Size AC field-wired conductors with 75°C ampacity (NEC) equal to or greater than their panel board circuit breaker rating.
 AC and DC input disconnect/protection - Provide accessible devices to remove input power in an emergency.
 Alarm Signals - Provide external current limiting protection. Rating 60V, 0.5A unless otherwise noted.
 Grounding - Connect the equipment chassis directly to ground. In enclosed equipment cabinets connect to the cabinet AC service ground
bus. In huts, vaults, and central offices connect to the system bonding network.
Precautions
 Install, service, and operate equipment only by professional, skilled and qualified personnel who have the necessary knowledge and
practical experience with electrical equipment and who understand the hazards that can arise when working on this type of equipment.
 Disconnect batteries from outputs and/or follow safety procedures while working on equipment. Batteries may be connected in parallel
with the output of the rectifiers. Turning off the rectifiers will not necessarily remove power from the bus.
 Do not disconnect permanent bonding connections unless all power inputs are disconnected.
 Verify that equipment is properly safety earth grounded before connecting power. High leakage currents may be possible.
 Exercise care and follow all safety warnings and practices when servicing this equipment. Hazardous energy and voltages are present in
the unit and on the interface cables that can shock or cause serious injury. When equipped with ringer modules, hazardous voltages will
be present on the ringer output connectors.
 Use the following precautions in addition to proper job training and safety procedures:
 Use only properly insulated tools.
 Remove all metallic objects (key chains, glasses, rings, watches, or other jewelry).
 Follow Lock Out Tag Out (LOTO) procedures: customer specified, site specific, or general as appropriate.
Disconnect all power input before servicing the equipment. Check for multiple power inputs.
 Wear safety glasses.
 Follow Personal Protective Equipment requirements: customer specified, site specific, or general as appropriate.
 Test circuits before touching.
 Be aware of potential hazards before servicing equipment.
 Identify exposed hazardous electrical potentials on connectors, wiring, etc.
 Avoid contacting circuits when removing or replacing covers;.
 Use a personal ESD strap when accessing or removing electronic components.
 Personnel with electronic medical devices need to be aware that proximity to DC power and distribution systems, including batteries and
cables, typically found in telecommunications utility rooms, can affect medical electronic devices, such as pacemakers. Effects decrease
with distance.
