1. Locate the 120 VAC power cord which is provided separately with the DHU. Use only

the AC power cord provided with the DHU or an equivalent UL/CUL listed 3-conductor,

18 AWG cord terminated in a molded-on plug cap rated 125 V, 15 A with a maximum

length of 6 feet (1.8 m).

Note: The DHU is intended to be used with a 3-wire grounding type plug which has a

grounding pin. Equipment grounding is required to ensure safe operation. Do not defeat

the grounding means. Verify DHU is reliably grounded when installed.

2. Place the DHU AC power ON/OFF switch, shown in Figure 24, in the OFF position

(press O).

3. Connect the receptacle end of the power cord to the AC connector on the DHU.

4. Route the plug end of the power cord to the specified AC outlet (per the system design)

and connect plug to outlet.

Warning: The current rating of the DHU is 2.0 Amps at 120 VAC. Avoid overloading circuits

which may cause damage to over-current protection devices and supply wiring.

5. Dress and secure cable per standard industry practice.

6. When all units of the Digivance ICS have been installed, refer to Section 4 of this

manual for the system power up and test procedures.

4.13 Create As-Built Drawing

Following installation, create an “as-built” drawing of the complete Digivance ICS system.

Using a drawing of the building floor plan, show the installed location of each piece of

equipment including the various Digivance electronic units, the antennas, the interface units,

and the microcell (if used). In addition, show the location and routing of all copper, coaxial,

and fiber optic cable runs used with the system. Retain the as-built drawing for reference

when troubleshooting or when planning for system expansion.
