Safety
Safety Statements
Read and follow these statements and those in equipment manuals.
• Do not install this equipment over combustible surfaces.
• Follow all national and local rules and regulations when making field connections.
• Compression Connectors
• For installations in the U. S. or Canada, use Listed/Certified compression connectors to terminate
Listed/Certified field-wire conductors where required.
• For 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.
• If the proper connector for the country of installation is not provided, obtain appropriate connectors and follow
manufacturer’s requirements and all local requirements for proper connections.
• Torque electrical connections to the values specified on labels or in the product documentation.
• Dress cables to avoid damage to the conductors (caused by routing around sharp edges or routing in areas
where wires could get pinched) and undue stress on the connectors.
• Size protectors (fuses or circuit breakers) as required by the National Electric Code (NEC) and/or local codes. Refer
to the equipment ratings to assure current does not exceed:
Continuous Load (List 1) - 64% of protector rating
Maximum Load (List 2 - typically end of discharge) - 80% of protector rating.
• Field-wired Conductors - Follow all National Electric Code (NEC) and local rules and regulations when making field
connections.
• Size field-wired conductors based on listed recommendations, National Electric Code (NEC) and/or local codes
based on 70°C ampacity.
• Insulation rating: 90°C minimum; 105°C (minimum) if internal to enclosed equipment cabinets.
• Provide an accessible AC disconnect/protection device to remove AC power from the equipment in the event of an
emergency. This device must open all poles and be connected together.
• 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.
• Alarm contacts are not fused within the equipment. Current limiting protection for these contacts must
be provided by external circuits. Exceeding these maximum ratings could result in fire or damage to the
unit. Alarm contacts are rated at 60V and 0.5A unless otherwise noted in the product Specifications
section.
• In enclosed equipment cabinets, the equipment chassis must be connected directly to the cabinet ac
service ground bus. For applications in huts, vaults, and central offices, the equipment chassis must be
connected to the system bonding network.
• Use only fuses and circuit breakers specified in the equipment documentation. Use of other parts may
result in injury to personnel or equipment damage.
• Use only GMT fuses provided with safety caps.
• This equipment 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). Different grounding
techniques 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.
