INSTALLATION

2.1

GENERAL

INSTALLATION AND OPERATION OF THIS DEVICE MAY EXPOSE HAZARDOUS VOLTAGES.
The INV-1200 series inverters are designed to be installed in a standard 19" relay rack or EIA type
enclosure. A set of accessory rack "ears" are provided for this purpose. These rack mount adapter
brackets may be mounted at the front panel or in the middle of the chassis. In both cases, the
adapters are held in place using # 10-32 x 3/8 inch hardware.
WHEN INSTALLING RACK MOUNT ADAPTERS, HARDWARE USED (MACHINE SCREWS) MUST
NOT EXCEED 3/8" IN LENGTH. LONGER SCREWS MAY DAMAGE INTERNAL COMPONENTS AND
Mount the unit in a suitable location as not to block the flow of cooling air at the front, rear, and
sides of the inverter chassis. This device will pull in cool air from the front and sides and exhaust
warm air from the rear. It is recommended that a minimum clearance of 3 inches be provided at
the front and rear and 1 to 2 inches on the sides. Enclosures should be vented.
When rack mounting, it is permissible to mount the inverter by the mounting ears only. If the unit
is intended for use in a mobile or other high vibration application the use of additional support for
the rear of the chassis is highly recommended.
2.2

WIRING

Wiring to the inverter will vary depending on input voltage and any options ordered. In addition,
local electrical codes must be considered for permanent installations. The North American
National Electrical Code (NEC) requires that separately derived AC sources such as back-up
generators, inverters, etc., must have one output conductor tied to a protective earth. This may be
accomplished with the INV-1200 series by following the recommended hook up diagrams
provided here.
ALL INSTALLATIONS AND VERSIONS OF THIS DEVICE REQUIRE THE USE OF THE SAFETY
EARTH CONNECTION TO THE CHASSIS. FAILURE TO DO SO MAY CREATE A SHOCK HAZARD.
THE VOLTAGE AND CURRENT PRODUCED BY THIS ARE HAZARDOUS.
Figure 2-1 (following page) illustrates the wiring for models that do not include the bypass
options. These units have two NEMA 5-15R type receptacles located on the rear panel.
Compatible loads may be plugged into these receptacles. Non-bypass type units are also
available with a rear mounted terminal block in place of the NEMA receptacles. This is noted as
the TB option. See section three of this manual for more information.
