Toshiba DK8, DK 16 manual General, Input Power Requirements, Site Considerations

1GENERAL

1.00This chapter defines the installation site re- quirements necessary to ensure a proper operat- ing environment for the STRATA DK8 and DK16. Also included are grounding requirements.

2INPUT POWER REQUIREMENTS

2.00The system requires an input power source of 117VAC nominal (85VAC ~ 135VAC), 50/60 Hz, 15 amps. The AC outlet is recommended to be dedicated and unswitched, with a solid third wire ground (refer to Paragraph 4). This is to eliminate interference from branch circuit motor noise or the like, and to prevent accidental power-off.

2.01To avoid accidental power turn-off, it is rec- ommended that an ON/OFF wall switch not be used on this dedicated AC circuit.

2.02An option Reserve Power Battery and Charger (HPFB) is available for use with the STRATA DK8 to serve as a power failure backup. For the STRATA DK16, a reserve power source (two customer-supplied 12-volt batteries) may be connected to the system to serve as a power failure backup.

3SITE CONSIDERATIONS

3.00Clearance and Location Requirements

3.01The key service units must be wall mounted. Figure 2-1 shows the minimum clearance require- ments for the STRATA DK8 system, and includes the recommended mounting location and clear- ance requirements for the optional HPFB. Figures 2-2 (Base Key Service Unit) and 2-3 (Base and Expansion Key Service Unit together) show the minimum clearance requirements for the standard
