3 INSTALLATION
Insure all terminating connections are clean and tight to prevent arcing and overheating.
Do not connect to a PV array capable of producing greater than 40 amps of short circuit current @ 25°C.
Do not connect to a PV array with an open circuit voltage (VOC) greater than 55 VDC.
For 12 volt battery
charging, the open circuit voltage of the PV array must be between 12-30VDC. For 24 volt battery
charging, the open circuit voltage of the PV array must be between 30-55VDC.
Important: Installations should meet all local codes and standards. Installations of this equipment should
only be performed by skilled personnel such as licensed electricians and Certified Renewable Energy (RE)
System Installers.

RECAUTIONS
All electronic circuits may be damaged by static electricity. To minimize the likelihood of electrostatic
damage, discharge yourself by touching an electrical ground (e.g.: copper pipe) prior to handling the unit and
avoid touching components on the circuit boards. The risk of electrostatic damage is highest when relative
humidity is below 40%.

OUNTING
The mounting location is important to the performance and operating life of the controller. The environment
must be dry and protected from water. If required, the controller may be installed in a ventilated enclosure
with sufficient airflow. Never install the TrakMax MPPT in a sealed enclosure. The controller may be
mounted in an enclosure with sealed batteries, but never with vented/flooded batteries. Battery fumes from
vented batteries will corrode and destroy the TrakMax MPPT circuits.
1. Place the TrakMax on a vertical surface protected from direct sun, high temperatures, and water.
The TrakMax requires at least 6 in (150 mm) of clearance above and below and at least 1 in (25
mm) on each side for proper air flow as shown in figure 3-1 below.
Figure 3-1: Required mounting clearance for airflow.
2. Place a mark on the mounting surface at the top of each keyhole (two per unit).
3. Remove the controller and drill a 3/32 in (2.5 mm) hole at the drill mark.
4. Insert a #10 screw into the pilot holes. Do not tighten the screw completely.
5. Leave a 1/4 in (6 mm) gap between the mounting surface and screw head
6. Carefully align the keyholes on the TrakMax with the screw heads and slide the TrakMax down
over the keyhole.
7. Tighten the keyhole screws.
8. Add two additional screws in the lower rectangular mounting cutouts.
Warning: Explosion/Corrosion Hazard
Do not mount on flammable surface material (e.g.: wooden wall).
