2-2 TSU 600 User Manual 61202076L1-1
Power Connection
The AC- powered TSU 600 is equipped with a captive, 8-foot power
cord, terminated by a 3-prong plug which connects to a grounded pow-
er receptacle.
Power to the TSU 600 must be from a grounded 90-120 VAC, 50/
60Hz source.
DC Powered Units
The DC-powered TSU 600 (1202076L1#DC or 1202076L2#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 mark-
ings on the unit.
Example:
A -48V source would be connected with the -48V return attached to the
(+) terminal and the -48VDC attached to the (-) terminal. Power must be
from a DC source in the range of 21 to 26 VDC or in the range of 40 to
56VDC.
The protective cover should be reinstalled over the terminal strip once
the power source is connected.
The DC-powered TSU 600 is to be installed only in restricted areas (ded-
icated equipment rooms, equipment closets, etc.) in accordance with Ar-
ticles 110-16 and 110-18 of the National Electric Code, ANSI/NFPA 70.
Backup Power Supply (600e only)
The TSU 600e has two power supply slots on the right side of the chassis.
The base unit is shipped with a single power supply. The TSU 600e is
fully operational with only a single power supply, which may be in-
stalled on either the left (power supply A) or the right (power supply B).
You can install a backup supply in the unused slot. The red System
Alarm LED on the front panel will indicate failure of either supply.
