Electrical Installation Instructions
Before installing the unit, please read carefully the Safety Instructions at the
beginning of this manual.
Make sure that all the switches on the M359 front panel are in the OFF position.
Verify that the Plug-in Battery Pack is properly installed and secured (see
Paragraph 6.3).
Verify that the electrical outlet that is powering the UPS is 115Vac/60Hz,
protected by a double-pole circuit breaker (or fuses) rated to between 32 to
46Amp.
Verify that the circuit breaker is off.
Verify that the cables that will interface with the UPS are wired in accordance
with Figure 2 (see next page).
Ground the UPS Chassis to your rack by using at least one of the GND
connections on the back-panel of the UPS. The GND conductor should be
AWG #8 or thicker. (For best EMI performance use wide and short low-
inductance braids).
Connect the AC cable coming from the 115Vac-wall outlet to the Input
Connector J1.
Connect the AC cable that feeds your equipment to the Output Connector J2.
Connect the monitoring and control cables from your server to the appropriate
connectors on the UPS back panel (RS-232, Ethernet SNMP, or Dry-contacts,
as applicable).
Turn on the 115Vac circuit-breaker that provides power to the outlet that feeds
the UPS.
The UPS now is ready for operation (see Paragraph 5).
