.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.
