Installing the Network Gateway Unit (NGU)
Installing the Network Gateway Unit (NGU)
The Network Gateway Unit (PN: 002-467) consists of a Back Box (with cover) with the following fitted on a chassis: a PSU3A
to Network Interface PCB and a Network Gateway Module (NGM) PCB. There is space for a PSU3A and two 12Ah batteries.

This basic configuration is used as an ID net Network Booster. The chassis allows a Fibre-optic PCB and RS232 PCB (for
connection of a network repeater) to be fitted.
The PSU3A provides a 28V output and a battery charger. The PSU3A to Network Interface PCB provides battery and PSU
fault monitoring, controls the battery charger and converts 28V dc to 5V dc (for the Network PCB). Alternatively, the NGU can
be powered by an external 28V supply connected at the PSU3A to Network Interface PCB.

Take suitable anti-static precautions, such as wearing a grounded
wrist strap, when following ALL instructions. Remove all packaging
from the kit and ensure that it has not been damaged in transit (and
that no items are missing - see checklist on the left) before proceeding
any further. If no damage is evident, proceed using the instructions
below. In the unlikely event that damage has occurred or items are
missing, DO NOT PROCEED, contact your supplier and refer to the
panel’s
Installation & Commissioning Manual
.
To install the Network Gateway Unit it is necessary to remove the
supplied electronics chassis (to prevent damage), fit the back box to
the wall, re-install the supplied electronics chassis, and fit any
required options. Instructions are given on the following pages.
