Fixed-tilt system using Purlin Bracket Kit
For fixed tilt systems, the Purlin Bracket Kit (PBK) is attached to a purlin or rail. ARES then mounts directly to this rail
if there is no correction needed to ensure the measurement plane is parallel to that of the array. The Purlin Bracket
Kit contains the hardware listed at the bottom of this section and is installed in the following steps:
1. Mount the angle bar to the racking using the self-tapping screws provided. Ensure that the ARES mounting
holes are aligned to the edge of the module so that the ARES unit sits flush to the module edge.
Note: the height from the top of module to the top of the bracket should measure 1.4”
2. Mount the ARES device using the ¼-20 button head screws to the bracket at approximately 10 in-lbs
torque. See Figure 7-3.
Hardware list:
• (1) 18” Aluminum angle bar
• (2) #8 5/8” Hex head self-drilling screw, stainless steel
• (2) 1/4-20 x 1/2" bolts
• (2) 1/4” fender washers
• (2) 1/4” split-lock washers

SMA antenna connection
A gold-plated SMA RF connector is located on the bottom-side of ARES. The supplied
cellular di-pole whip blade antenna must be threaded onto the SMA connector to
send/receive cellular data. If the antenna is not connected, ARES will not output data or
functional properly.
The antenna is omni-directional with uniform power in all directions. The optimum
antenna orientation is
straight (not bent)
for highest signal power and quality, as seen
in Figure 8-1.
