Installing the Power Max Level 2 Charging Station
1. See Figure 4-1. Secure the Level 2 Charging Station mounting bracket to the wall using appropriate screws and
bracket holes, as shown in Figure 4-1. Thread 1/4-in. expansion bolts through bracket offset holes into masonry
walls as shown and torque to 78 lb·in (8.8 N·m). Thread 2-in., or longer, No. 8 wood screws through bracket
inline holes into finished walls supported by wood studs and torque to 26 lb·in (3 N·m).
Note:
The Level 2 Charging Station must be mounted at a sufficient height from grade such that the height of the plug
dock is located between 24–48 in. (0.6–1.2 m) from grade per NEC Article 625.
Figure 4-1. Mounting bracket use on masonry wall (left) and finished wall (right)
2. See Figure 4-2. Choose appropriate conduit in accordance with all applicable state, local, and national electrical
