The APC Smart UPS SMT1000I contains internal batteries and may present a shock hazard even when disconnected from the branch circuit (mains). Before installing or servicing the equipment check that the:

• Input circuit breaker is in the OFF position.
• Internal UPS batteries are removed.

• Use tools with insulated handles.
• Do not handle any metallic connector before power has been disconnected.
• For models with a hardwired input, the connection to the branch circuit (mains) must be performed by a qualified electrician.
• The protective earth conductor for the UPS carries the leakage current from the load devices (computer equipment). An insulated ground conductor is to be installed as part of the branch circuit that supplies the UPS. The smt1000ic conductor must have the same size and insulation material as the grounded and ungrounded branch circuit supply conductors. The conductor will typically be green, with or without a yellow stripe.
• Leakage current for a pluggable, Type A UPS may exceed 3.5 mA when a separate ground terminal is used.
• The UPS smt1000ic  input ground conductor must be properly bonded to protective earth at the service panel.
• If the UPS smt1000ic input power is supplied by a separately derived system, the ground conductor must be properly bonded at the supply transformer or motor generator set.

• Check that all branch circuit (mains) and low voltage (control) circuits are deenergized, and locked out
  before installing cables or making connections, whether in the junction box or to the UPS.
• Wiring by a qualified electrician is required.
• smt1000ic Check national and local codes before wiring.
• Strain relief is required for all hardwiring (supplied with select products). Snap in type strain reliefs are recommended.
• All openings that allow access to UPS hardwire terminals must be covered. Failure to do so may result in personal injury or equipment damage
• smt1000ic Select wire size and connectors according to national and local codes.
