Connecting To Utility Power; Connecting The Loads - Delta M-1K User Manual

4.2 Connecting to Utility Power

1. Please read pre-connection warnings before connection.
2. Use the provided input cable to connect the UPS and a wall socket with earthing-
contact. If the wall socket does not have an earthing connection, please ground
the UPS via the ground terminal. Please see 2.5 Rear Panel for ground terminal
location.
3. Check whether the S.W.F (Site Wiring Fault) LED illuminates or not. If yes, pull
out the mains plug, turn it and plug it correctly. Please note that the left pin of
the UPS's AC input socket is L phase. If the S.W.F LED still illuminates, please
contact service personnel.
NOTE :
1. The UPS will charge its internal batteries and the Delta external battery
pack (if the Delta external battery pack is connected and its circuit breaker
is turned on) whenever the UPS is connected to an AC source. There is
an acceptable AC voltage present.
2. It is recommended that you charge the UPS's batteries for a minimum of 6
hours before use. If you don't do this, the UPS may be used immediately
but the 'On-Battery' runtime may be less than normally expected.
3. If the UPS is going to be out of service or stored for a prolonged period of
time, you must recharge the internal batteries at least 6 hours once every
3 months. If a Delta external battery pack is connected, the recharging
time should not be less than 12 hours.
4. The batteries will immediately begin charging upon availability of the input
power.
