IMPORTANT SAFETY PRECAUTIONS
• The XM2 Series 2 Power Supply must only be serviced by qualified personnel.
• Use proper lifting techniques whenever handling power supplies, or batteries.
• The XM2 Series 2 Power Supply contains more than one live circuit. Even though AC voltage is not
present at the input, voltage may be present at the output.
• Always switch the battery circuit breaker to OFF before connecting or disconnecting the battery pack, or
whenever installing or removing the inverter module. This greatly reduces the chance of spark.
• The battery pack, used to provide backup power, contains dangerous voltages. Battery inspection or
replacement should be performed by qualified personnel.
• Remove all rings, watches and other jewelry before servicing power supply.
• The USM2 circuit board contains static-sensitive components, please follow all appropriate ESD handling
practices.
• Always verify USM2 configuration especially after upgrading or modifying the XM2 Series 2 Power
Supply.

Precautions - Handling Circuit Boards
• DO NOT attempt to install or remove any control board without first reading the XM2 power supply
manual for instructions.
• As the USM2 circuit board contains static-sensitive components, please follow all appropriate ESD
(Electro Static Discharge) handling practices. For additional safety handle the USM2 card by the edges,
and keep fingers away from card edge connectors.
