Warning The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated.
The proper wiring sequence is ground to ground, positive to positive, and negative to negative. The
ground wire should always be connected first and disconnected last. Statement 239
Caution Do not overtorque the terminal block contact screws. Recommended torque is 8.0 ± 0.5 in-lb
(0.9 ± 0.05 N-m).

Step 6 Install the plastic cover over the terminals. (See Figure 3-17.)
Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover
installed. Operating the unit without the cover in place will invalidate the safety approvals and pose
a risk of fire and electrical hazards. Statement 117
