WARNING
Risk of serious personal injury or damage to equipment and property! Always
observe the following:
Use an appropriately rated over-current protection device in line with the
main battery connection to the Inverter
Use an appropriately rated over-current protection device in line with the ac
input connection to the Inverter (if transfer relay option is installed)
Use an appropriately rated disconnect switch or circuit breaker in line with
the Inverter dc and ac inputs to enable installation and service with the
battery and ac power source disconnected
Shut off or disconnect the dc and ac power sources before connecting or
disconnecting wiring
Use wire and connectors rated for the maximum load current and size of
fuse or circuit breaker, and keep cable lengths as short as practical
Ensure battery voltage matches the rating of the model of inverter in use
Carefully observe wiring polarity when making input connections
Securely tighten all connections
Install the wiring box and cover and use appropriate wiring strain relief
devices on all wires
The ac NEUTRAL line may be internally bonded to the chassis (if ground
bonding screw is installed). Ensure chassis is connected to earth ground
before use
Batteries can explode or arc! Wear suitable face and hand protection and
use insulated tools when working with batteries
Do not attempt to service any internal parts. Refer all product service to an
authorized ICT Ltd. service facility
CAUTION
Risk of personal injury or damage to equipment! Always observe the following:
Install in a protected environment, keep sources of moisture away from unit
Ensure the total power consumption of the load does not exceed the rated
load capacity of the inverter
Do not block air inlet or outlet openings in the inverter

INSTALLATION
Perform a quick physical check of the unit as it is being taken out of the box to
ensure it has not been damaged during shipping. Check for the included parts
and accessories shipped with your unit:

Innovative Circuit Technology Ltd. 5
3 pin Form-C alarm connector plug
Wall mounting bracket, with mounting screws (4), installed
Instruction Manual
Bus bar connection 5/16 inch bolt, nut, and washer set (2)
Mount the optional wiring junction box base (part of the Wiring Junction Box kit
ICT-DCWB) to the back of the inverter with 4 supplied screws, as shown in Figure
1. Knockout the plugs and install conduit fittings or wire strain relief clamps in
the wiring box openings to be used for the installation, as required. The inverter
must be installed in a restricted access environment such as an enclosed
equipment rack if the back panel wiring junction box is not used.
Figure 1: Wiring Junction Box Installation
Mount the inverter using the wall mount bracket (included) or the optional 19
inch rack-mount tray (ICT-RMK4) using the 4 mounting screws on the bottom of
the inverter, as illustrated in Figure 2. Keep the distance to the battery bank as
short as practical to minimize power loss in the high current wiring. (see DC Wire
Sizing Guide table)
Figure 2: Inverter Wall Bracket Mounting
6 Innovative Circuit Technology Ltd.
The inverter may be mounted horizontally on a shelf, or the ICT rack tray, or in a
vertical wall mounted orientation. Install the unit with either side located on top
(as shown in Figure 3) when wall mounting to ensure proper cooling and long
term safe operation of the inverter. (Mounting hardware not included)
Figure 3: Approved Mounting Orientations
Connect the chassis ground stud on the back panel to a reliable earth ground
point.
Ensure the inverter switch is in the off position, then connect the dc input wiring
from a suitable deep-cycle lead-acid battery to the inverter using appropriately
rated wire size (see DC Wire Sizing Guide), and an in line over current protection
device/disconnect switch or breaker (with disconnect switch in “off” position).
Terminate wire with appropriate size of ring tongue to fit the 5/16” input bus bar
mounting bolts.

CAUTION
Risk of personal injury or damage to equipment!
Ensure the nominal battery voltage is correct for the model of inverter, and that
the battery positive is connected to the inverter input positive (+) terminal,
battery negative is connected to the inverter negative (-) terminal.
Table 1 : DC Wiring Minimum Sizing Guide, Recommended Minimum Battery Size
Connect the AC loads to be powered by the inverter to the AC OUT wire clamp
connector (Line, Neutral and Ground) located on the back panel, (see Figure 4)
using wire rated for 15A. (14 – 12AWG) Alternatively cord connected devices
may be directly plugged in to the AC outlets located on the inverter front panel.
On units with the Transfer Relay (option “T”) connect the external AC power
source (grid power, or AC generator) to the AC IN wire clamp connector on the
back panel of the inverter, using wire rated for at least 15A (14 – 12AWG), with
the AC power source switched off.

CAUTION
Risk of personal injury or damage to equipment!
AC input wiring from the grid or other power source to the inverter must be
protected using a branch rated circuit breaker of 15A or lower value.
Connect the external alarm monitoring wiring to the Form-C alarm contact
output if desired. (See Alarm Output Contacts table, below) Plug the Ethernet
network (CAT-5) cable in to the optional Network port on the back panel (option
“C” equipped units only), routing the alarm and network cable through the
plastic bushing immediately adjacent to the connector on the side of the optional
wiring box tray.

Check that all connections to the inverter are correct and tight, then tighten the
wire strain relief clamps in the wiring junction box (if used), and install the wiring
box cover.
Set the external battery disconnect switch or breaker to “on”.
OPERATION
With the unit mounted, wired, and powered as described in the INSTALLATION
section, turn the front panel power switch to the ON position and check that the
green AC indicator on the front panel is flashing slowly, indicating the inverter
battery powered AC output is on.
Switch the external ac source disconnect device to ON (if an external AC source is
being used, Transfer Switch option “T” only), and observe that the green AC
indicator on the front panel is now on continuously, indicating the external AC
source is present and powering the load. The inverter output will now be
powered directly from the external AC source.
The connected AC loads should now be operating normally, powered with up to
1500W (3000W momentary peak) of battery backed AC power.
