SAFETY & WARNINGS

Read this manual carefully and understand all Warnings and Cautions before connections are
made to the Inverter. If unsure about any aspects of the installation call ICT Technical Support
at [phone], 8:00AM to 4:30PM Pacific Standard Time.

4WARNING: Check the battery polarity and voltage before connecting the unit. Incorrect

polarity will damage the unit.

4WARNING: Make sure that all the DC connections are tight. Loose connections could result

in Overheating and can be a potential hazard.

4WARNING: The AC neutral lead is internally bonded to chassis. The chassis must be

bonded to earth ground through the external ground connector located at the back of the unit.

4WARNING: Do not attempt to operate the Inverter from any power source other than a

battery.
The 12 Volt Inverter (ICT300-12SNV) must be connected to a 12 Volt battery.
The 24 Volt Inverter (ICT300-24SNV) must be connected to a 24 Volt battery.
The 48 Volt Inverter (ICT300-48SNV) must be connected to a 48 Volt battery.
Connecting the Inverter to any other battery may damage to unit.

4WARNING: Calculate the total power consumption (W) of the output load. Make sure the

total power consuption does not exceed the rated load capacity of the Inverter.

4CAUTION: No user serviceable parts inside. Only ICT personnel are authorized to service

the unit.

4CAUTION: It is the installerʼs responsibility to ensure compliance with all applicable

installation codes and regulations.

4CAUTION: Before any connections are made to the unit or system, be sure to disconnect

the battery terminals. Always disconnect the grounded battery terminal first. When
reconnecting, connect ungrounded terminal first, and grounded terminal last.

4CAUTION: Avoid mounting the unit near sources of moisture, flammable gases or fumes.

4CAUTION: Do not block the fan opening on the front of the Inverter.

4CAUTION: Follow the provided wire size recommendations provided in this manual. DC

connection cables should be as short as possible and large enough to handle the required
current in accordance with the electrical codes or regulations applicable to your installation.
Cables that are not an adequate gauge, or are too long, will result in excessive voltage drop,
decrease inverter performance, and possibly damage the unit.

4CAUTION: To ensure that the Inverterʼs safety features are not compromised, use the

Inverter as specified in the manual and do not substitute parts or make any unauthorized
modifications.

4Install an in-line fuse (not supplied) in the positive lead from the battery to the Inverter (see

page 4).

INTRODUCTION

Whether your communications site is off the grid, or designed to operate from DC power for
uninterrupted quality of service, certain components still require high quality, reliable AC sine
wave power to operate.

The ICT SITE INVERTER 300 is a low profile, high performance sine-wave inverter that
converts DC energy from your battery source into 300 watts of utility grade power for site
equipment that requires AC electricity, such as radio links, multiplexers, routers, or digital
video recorders. ICT inverters provide extremely low harmonic distortion and high efficiency,
meaning that your equipment receives extremely quiet, high quality power.

Up to three ICT SITE INVERTER 300’s can be mounted in a single 1RU 19 inch rack shelf, to
provide almost 1kW of power (non-parallel) and six AC outlets in an ultra-compact, space
saving design.

Other options include an accessory kit that provides two AC outlets on the front faceplate of
the inverter rack.

FEATURES

The ICT SITE INVERTER 300 is designed specifically for communications site applications,
and includes the following features:

- Two rear-facing AC outlets for easy access to the equipment that needs to be powered.

- Rear-mounted DC input studs for connection to the DC battery source.

- A grounding stud on the rear of the unit.

- Front mounted power switch and LED indicator lights.

- Thermo-controlled, ball bearing brushless cooling fan blowing front to back ensures the best
thermal performance and longevity for the internal components.

- Air intake is from the front of the unit.

- LED indicators provide information on AC status and on the built-in protection features,
including input voltage condition, overload, and temperature shutdown conditions.

- Operating temperature range from –20C to +60C.

- Capable of handling up to twice its rated capacity, or 600 watts, for up to three seconds.

OPTIONS

- 1RU 19” mounting rack (model number ICT-RM1U) holds 1, 2, or 3 inverters.

- Front AC Outlet Kit (ICT-ACF) provides two AC power outlets on the front of the ICT-RM1U
rack mount kit (requires one open mounting position and one Site Inverter 300). Includes AC
power cord to route AC from the Site Inverter 300 to the front facing outlets.
