Chapter 2. Installation

Power Connection

The AC powered TSU 600 is equipped with a captive eight-foot power cord, terminated by a three-prong plug which connects to a grounded power receptacle.

Power to the TSU 600 must be from a grounded 115

VAC, 60 Hz source.

DC Powered Units

The DC powered TSU 600 (1200.076L2#DC) is equipped with a terminal strip on the rear of the unit. The power source should be connected to the terminal strip according to the polarity markings on the unit. For example, a -48V source would be connected with the -48V return attached to the (+) terminal and the - 48V DC attached to the (-) terminal. Power must be from a DC source in the range of 21 to 26V DC or in the range of 40 - 56V DC.

The chassis ground connection on the rear panel is electrically isolated from the power input. The protective cover should be reinstalled over the termi- nal strip, once the power source is connected.

The DC powered TSU 600 is to be installed only in restricted areas (dedicated equipment rooms, equip- ment closets, or the like) in accordance with Articles 110-16 and 110-18 of the National Electric Code, ANSI/NFPA 70.
