2. Mounting
3. Gas connections
4. Electrical connections
5. Installing the Micro-Fuel Cell

3.1 Unpacking the Analyzer
The analyzer is shipped with all the materials you need to install and
prepare the system for operation. Carefully unpack the analyzer and inspect
it for damage. Immediately report any damage to the shipping agent.
3.2 Mounting the Analyzer
The Model 3020T is designed for bulkhead mounting in hazardous
environments. There are four mounting lugs—one in each corner of the
enclosure, as shown in Figure 3-1. The outline drawing, at the back of this
manual, gives the mounting hole size and spacing. The drawing also con-
tains the overall dimensions. Do not forget to allow an extra 1
3 /
8
" for the
hinges.
Be sure to allow enough space in front of the enclosure to swing the
door open—a 16 1 /
4
" radius, as shown in Figure 3-2.
All electrical connections are made via cables which enter the explo-
sion-proof housing through ports in its side. No conduit fittings are supplied.
The installer must provide two 3/4" NPT and two 1" NPT adapters and the
appropriate sealing conduit.
