WARNING
Risk of serious personal injury or damage to equipment and property! Always observe the
following:
•Install and operate unit in a restricted access location. A restricted access area is an area to
which access can be gained only by service personnel using a special tool, lock and key, or
other means of security and which is controlled by the authority responsible for the location.
•Install unit in locations where children are likely not to be present.
•Due to potential high leakage currents, install earth connection to the unit before connecting
AC input
•Use caution when handling unit under load as surface can reach high temperatures.
•Operate the supply from a grounded 3-wire 120Vac or 230/240Vac source (50 or 60Hz) with a
branch circuit breaker (see chart on page 14 for breaker rating).
Always observe the following for applications requiring a backup battery:
•Use only a Lead-Acid or Lithium-Ion battery with rating and capacity appropriate for the model
of supply in use
•If a Lithium-Ion battery is used, it must have an integrated battery management system (BMS)
to protect the battery cells from inappropriate voltage or current levels
•Use an appropriate DC over-current protection device in line with the back-up battery
connection
•Use a disconnect switch or circuit breaker in series with the battery connection, to ensure
installation and service is done with the battery de-energised
•Use wire and connectors rated for the load current and size of battery fuse or circuit breaker
•Ensure battery polarity is correct before connecting
•Do not attempt to charge a frozen battery
•Handle batteries with care, never short circuit battery terminals
•Always install batteries in a well-ventilated area
•Always consult with battery manufacturer and observe all battery manufacturer
recommendations
CAUTION
Risk of personal injury or damage to equipment! Always observe the following:
•Install in a protected environment, keep sources of moisture away from unit
•Ensure the total power consumption of the load does not exceed the continuous rated
capacity of the power supply output
•Do not block air inlet or outlet openings in the unit
•Do not place the power supply directly above or below an exposed battery, due to possible
presence of corrosive and/or flammable gasses
NOTE
Due to the breaker detection circuitry internal to the load distribution module, it may be possible to
measure a voltage on the output terminal(s) even if that output’s breaker is open (with no load
connected). This is normal operation. The detection circuitry is a high-impedance circuit, and while a
voltage may be present on the output terminal, it is purely a signal voltage and does not support
loading. Any load device connected to the output will immediately pull this voltage to zero volts.
