Safety chain or cable, rated 50 pound minimum working load, 250 pound minimum breaking strength is required
to hang the unit in a T-Grid system. Failure to correctly install unit will cause an unsafe condition!
AC Connections
CAUTION:
• All
Tucson Micro
inverter system units contain hazardous AC and DC voltages. Because of these voltages, a qualified
electrician must install the
Tucson Micro
inverter system, AC line service, and batteries. The electrician must install the
AC line service according to local, state and NEC codes and must be familiar with batteries and battery installation.
• Before installing, maintaining, or servicing the unit, always remove or shut off all sources of AC power to the
Tucson
Micro
inverter system. Disconnect the unit battery leads to make sure the unit will not supply output voltage. Turn the
AC line input circuit breaker OFF at the service panel.
• Whenever AC and/or DC voltage is applied, there will be AC voltage inside the
Tucson Micro
inverter system unit; the
unit can supply power from AC line or from its batteries. To avoid equipment damage or personal injury, always assume
that there may be voltage inside the
Tucson Micro
inverter system.
• Remove rings, watches, and other jewelry before installing the AC wiring. Always wear protective clothing and eye
protection and use insulated tools when working near batteries. Whenever servicing an energized unit with the inside
panel open, electric shock is possible; follow all local safety codes. TEST BEFORE TOUCHING!
• To reduce the risk of fire or electric shock, install the
Tucson Micro
inverter system and the batteries in a
temperature-controlled and humidity-controlled indoor area free of conductive contaminants. See the
Installation
Requirements
section on page 4 for operating environment specifications.
