Installation
Introduction
This chapter contains unpacking, inspection and installation instructions for installing and powering up the
WRH.
Site Survey
Powerwave recommends that a site survey be performed prior to equipment ordering or installation.
Performing a detailed site survey reduces or eliminates installation and turn-up delays. Pay particular
attention to power plant capacity, cooling needs, floor space, and RF/DC cabling/breaker requirements.
Cabinet dimensions and weights are listed in Chapter 5.
Unpacking and Inspection
This equipment has been operated, tested, and calibrated at the factory. Carefully open containers to remove
equipment. Retain all packing material that can be reassembled in the event unit must be returned to the
factory. Perform the following steps:
❑ V
isually inspect equipment for damage that may have occurred during shipment. If possible, in the
presence of
the delivery person.
❑ Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous
packing material in connectors.
If equipment is damaged, file a claim with the carrier once the extent of any damage is assessed.
If equipment must be returned to factory, please contact factory for a Return Material Authorization (RMA),

WRH Location
The WRH is designed with a weather proof outdoor cabinet that can be mounted without any kind of shelter
from rain, snow or hail. The same unit can be installed indoors. A preferable site for the WRH is a location free
of obstructions, easily accessible and allows for proper air-flow and ventilation.
If a WRH is installed outdoors and can be exposed to direct sunshine, it is essential that air circulates around
th
e WRH with no obstacles
. The operating temperature must not exceed 131°F (55°C). A shelter can be used
to shade the WRH from direct sunshine.
Never open a WRH when rain, snow, hail, high humidity or high winds are present unless some kind of
te
mporary shelte
r can be erected.
Mounting
The WRH is easy to mount using the provided mounting bracket, which has 9/16-inch (14mm) holes for 3/8-
inch (10mm) or 1/2-inch (12mm) fixing screws. Clamps with C-C measurements of 3.5-inch (90mm), 5.3-inch
(135mm), 5.7-inch (144mm), 8.1-inch (205mm), 9.8-inch (250mm), and 11.8-inch (300mm) can be used as
well. The vertical C-C measurement for these is 16.2-inch (411mm). There is a 9/16-inch (14mm) single hole
in the middle of the mounting bracket, marked ‘A’ in the figure, which is intended for a locking screw to lock the
bracket into place.
