• The DC input power positive pin must be at positive potential relative to the DC negative pin
for the Gateway to function. If the polarity is reversed, the unit will not sustain damage but
will not operate until the polarity is corrected.
• The Pearl Gateway DC power source must meet SELV requirements.
2.2 Unpacking and Inspection
The following should be considered during the unpacking of a new Pearl Gateway.
1. Inspect the shipping carton and report any significant damage to TEKTELIC.
2. Unpacking should be conducted in a clean and dry location when possible.
3. Do not discard the shipping box or foam inserts as they will be required if a unit is
returned for repair or re-configuration.
2.3 Required Equipment for Installation
The following tools are required to install the Pearl Gateway system:
1. An imperial and a metric socket with Torx set and a torque wrench.
2. Anti-oxidant compound (NO-OX-ID, Penetrox, Noalox, Ox-Gard or equivalent).
3. A small wire brush or emery cloth.
4. A clean cloth.
5. Weatherproofing tape kit for the RF connectors (Scotch Wireless Weatherproofing Kit,
WK-101 recommended).
6. Four M4 screws with locking hardware for Gateway mounting (length according to
application, see next section).
7. Four M8 screws with locking hardware for TTU mounting according to application (see
next section).
2.4 Pearl Gateway Mounting
The Pearl Gateway Modules are designed to be mounted to a flat surface using site supplied
M4 x 0.7 stainless screws with locking hardware, one at each of the four mounting points as
illustrated in Figure 6 for the Mobile Gateway Module and Figure 7 for the Fixed Gateway
Module. These four mounting screws are to pass through pre-drilled holes in the mounting
surface. The mounting drill-hole pattern is on a square as indicated in Figure 6 and Figure 7. The
dill size shall be selected for a slight clearance to M4 screws.
Mounting the Gateway module requires access to both sides of the mounting surface; this may
require two persons in cases where the mounting surface is large.
