Safety Statements
See equipment specifications for installation and environmental limitations.
• 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.
