CHAPTER 2 CONNECTING POWER AND SURGE 23
e Click 200 contains three terminal connectors on both the top and the bottom of the
module (see Figure 2.3). e terminal connectors are removable and are red-keyed, al-
lowing each connector to plug into only one specic jack. is both simplies the wiring
process and reduces the possibility of wiring errors.
