2.2.1 AC Outlets
120VAC output models (-N suffix) are fitted as standard with 2 x NEMA 5-15 outlet sockets, rated at 12A
maximum each.
Electrical
Hazard.
Contact with water can cause electric shock.
2.2.2 Ventilation openings.
Do not obstruct. Allow at least 3” (~75mm) for clear airflow.
2.2.3 AC mains breaker. This breaker must be operated by qualified personnel only. it must be switched on to
allow the utility AC to be fed to the outlet sockets when the unit is on bypass.
2.2.4 Alarm connector: This connector MUST NOT be connected to SELV circuits.
NO means: Normally Open
NC means: Normally Close
COM means: Common.
The alarm indicates that an external AC source is available for by-pass purposes.
When the inverter is switched on and an AC supply is available to the by-pass circuit, NC and COM are
shorted.
When the inverter is switched on and there is no AC supply available to the by-pass circuit, NO and COM
are shorted.
When the inverter is switched off, NC and COM are shorted.
See section 2.7 for details about using this function.
2.2.5 DC Input Terminals.
Used to connect to a -48V battery or other suitable DC source.
[+] must be connected to the positive terminal of the battery or DC source.
[-] must be connected to the negative terminal of the battery or DC source.
WARNING: Reverse polarity connection will blow an internal fuse and may also damage the unit
beyond repair.
Pay particular attention when connecting to a -48V battery system.
In such event the
unit will have to be returned to TRANSTECTOR for repair if possible and any remaining warranty
will be void.

2.2.6 RS232 connector, 9-way D-type.
This connector allows for connection to a PC serial port and various status information obtained.
See section 8 for more details.
2.2.7 Frame Ground.
Connect to the frame ground of the cabinet or rack in which the unit is installed using 8AWG wire.
WARNING!
Operation of this inverter without a proper ground
connection may result in an electrical safety hazard.
2.3 Installation
WARNING!
Shock Hazard. Before proceeding further, carefully check that
the unit is NOT connected to any batteries and that all wiring is
disconnected from any electrical sources.
Do not connect the output sockets to an incoming AC source.
This power inverter should be installed in a restricted access location such as a Telecommunications room or IT room,
where access is limited to service and other qualified personnel and which can only be entered by use of a tool lock or
key which is controlled by the authority that is responsible for the location. Bare parts of any terminals that present a
hazardous energy level shall be located or guarded so that unintentional bridging by conductive materials that might be
present is unlikely. A readily accessible disconnect device shall be incorporated in the building installation wiring prior to
connection to the inverter. These locations should additionally meet the following requirements:
