is off. Otherwise, severe injury to the installer or damage to the unit may result.

Bonding (safety) ground, power and frame ground, and alarm connections and cabling are marked for ease of installation [see ground lug location (labeled BONDING WIRE MIN #10 AWG)], TB1, and TB2 on the rear panel of the HMS-318 List 3 Shelf, and the following procedures for proper safety ground, power, alarm, and optional fan (alarms) connections (see Figure 1-2 on page 1-3).

Bonding (Safety) Ground Procedure

To connect the Bonding (Safety) ground to the HMS-318 List 3 Shelf, complete the following steps:

Note: The ground wire exiting the HMS-318 List 3 Shelf is terminated with a ground lug. The lug can be either a one-hole or two-hole lug. The surface of the lug that connects to the HMS-318 List 3 Shelf should be cleaned with an antioxidant. The same should also be applied to the surface of the telco-style rack where the connection is to be made. The #12 Hexhead screw (supplied) is used to connect the grounding lug to the HMS-318 List 3 Shelf.
