3.4 Strain reliefs installation
Close to the inverter, prepare to drill two holes (about 3 inches apart (7.6cm) in the truck’s floor to install the
two strain reliefs already installed on the DC cables. On a truck with a “sleeper”- be careful not to drill on cab
cross-members as it may weaken the cabin structure. Also, be careful not to drill into hoses (Coolant or AC).
Drill 1/8” pilot holes first to confirm you are in a convenient location to drill the larger holes. Strain reliefs vary
in size upon the inverter capacity. Make sure to use the right size hole saw.
3.5 Ground (not the negative)
The inverter housing must be connected to the chassis or to a metallic panel connected to the chassis. This
grounding procedure conforms to most electrical codes that require to derived AC sources to ground in case of
malfunctioning. Most cab structures allowing for a strong install point for an inverter are generally linked to the
chassis of the vehicle. For this reason, NO GROUNDING material is included in the CM Series installation kits.
To make sure that your inverter is grounded properly, run a 24 volt test light from the positive terminal of your
battery to your inverter mounting point; if the light comes on, your installation is OK. If not, use the lug on the
rear panel and a #8 AWG copper cable to connect the inverter to a good grounding point.
WARNING! Do not connect the ground lug to the negative input of the inverter. It will not provide the
adequate level of safety required by most electrical codes.
