A
“Caution”
identifies conditions and actions that may damage the power supply or associated
equipment.
WARNING
This power supply and its associated hardware (enclosure, cabling) may contain equipment(s), or
parts which have accessible hazardous voltage or currents.
To avoid injury:
• This power supply and its associated hardware must be serviced by authorized personnel only.
• Verify AC line power is de-energized prior to installation or service.
• Remove all conductive jewelry or personal equipment prior to servicing equipment, parts, connectors,
wiring, or batteries.
• Read and follow all installation, equipment grounding, usage, and service instructions included in this
manual.
CAUTION
This Power Supply may contain equipment(s) or part(s) that may be damaged or cause damage to other
equipment if improperly used.
To avoid damage:
• An agency-approved service disconnect switch with overcurrent protection must be provided by the
installer. It must be connected between the utility power source and the power supply. Subject to local
codes, the service disconnect switch must be an outdoor, NEMA 3R enclosure, rated 120/240V, with a
non-interrupted termination. The disconnect shall be a circuit breaker type provided with a dual 15A
circuit breaker for the main and neutral input lines. Due to the ferroresonant transformer, the circuit
breaker should be a high inrush magnetic type able to withstand short duration inrush currents.
• Overcurrent protection and disconnecting means for the AC output are to be supplied by the installer as
required by local codes.
• Use #16AWG (1,28mm
2
) minimum Copper, 75C, for all utility input wiring.
• Prior to installation, verify that the output voltage from the enclosure or its equipment match the voltage
requirements of the connected equipment (load).
• Verify the enclosure which houses the power supply has sufficient ventilation to maintain the power
supply in its specified operating temperature range (-40°C to +55°C).
• Do not operate the power supply in an environment containing corrosive or conductive gas, vapor,
liquid, or dust.
• When servicing the power supply, use on specified replacement parts.
• Servicing is to be performed only by authorized personnel.
