3.4 Electrical Installation

3-4-1. Power connection

For a model with AC power supply, AC power (90~250VAC) is supplied to the

MULTIPLEXER UNIT through a standard IEC 3-prong receptacle, located on the rear of

the chassis. For a model with DC power supply, DC –48V (20~60VDC) is connected to the

terminal block, observing the proper polarity. In the AC/DC model, both IEC receptacle and

DC terminal block are provided for dual power operation. The MULTIPLEXER UNIT

should always be grounded through the protective earth lead of the power cable in AC

installations, or via the frame ground connection for DC installations.
