.OO This 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.

2 INPUT POWER REQUIREMENTS

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

2.02 An 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 DKl6, a reserve power source
(two customer-supplied 12-volt batteries) may be
connected to the system to serve as a power
failure backup.

3 SITE CONSIDERATIONS

ments for the STRATA DK8 system, and includes
the recommended mounting location and clear-
ance requirements for the optional HPFB. Figures
