Installation Area Limitations
•
Environmental Limitations
•
Do not install this equipment over combustible surfaces.
•
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.
•
Follow all national and local rules and regulations when making field connections.
•
Torque electrical connections to the values specified on labels or in the product documentation.
•
DC output cables must be dressed 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.
•
External protectors (fuses or circuit breakers) must be sized 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.
•
Insulation on field
-
wired conductors must be rated no less than 90°C. Size conductors based on
listed recommendations. Wiring internal to enclosed equipment cabinets must be rated at 105°C
(minimum).
•
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.
•
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. See the Specifications section for alarm contacts ratings.
•
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 GMT fuses provided with safety caps.
