ducted manually with the on/off button at any time. See section 5.2.
The UPS features user-replaceable hot-swappable batteries. Batteries can be replaced without having to re-
move power from the loads or send the UPS in for service.

agement software.
Telephone Line and Network Surge Protection

2. Safety
CAUTION!
To reduce the risk of electric shock in conditions where load equipment grounding cannot be verified,
disconnect the UPS from the AC power outlet before installing a computer interface or accessory slot
signal cable. Reconnect the power cord only after all signaling connections are made.
Connect the UPS to a two-pole, three-wire grounding AC power outlet. The receptacle must be con-
nected to appropriate branch protection (fuse or circuit breaker). Connection to any other type of re-
ceptacle may result in a shock hazard and violate local electrical codes.
