SECTION 2
INSTALLATION AND ACCEPTANCE
2.1 UNPACKING
Inspect the unit for any possible shipping damage immediately upon receipt. If damage is evident, notify the carrier.
DO NOT return an instrument to the factory without prior approval. Do not destroy the packing container until the unit
has been inspected for damage in shipment.
2.2 POWER
REQUIREMENTS
The AC Power System has been designed to operate from a three-phase AC line voltage. The input line voltage may
be between 187 volts and 252 volts line-to-line for the standard product or 342 to 456 volts line-to-line for the UP option.
The frequency may be between 47 Hz and 440 Hz. Select an AC input line and hookup wire to the AC Power System
that will deliver 40 amps per phase and still supply a minimum of 187 volts line-to-line. Refer to Figure 2-2 for circuit
breaker requirements of all multichassis power system. The 6000L power system must have a minimum of 208V
L-L
for
a full rated load on the output.
2.3 MECHANICAL
INSTALLATION
The power system has been designed for rack mounting in a standard 19 inch rack. The unit should be supported from
the sides with optional rack slides. See Accessory Equipment/Rack Slides in paragraph 1.3. The cooling fan at the
rear of the unit must be free of any obstructions which would interfere with the flow of air. A 2.5 inch clearance should
be maintained between the rear of the unit and the rear panel of the mounting cabinet. Also, the air intake holes on the
sides of the power source must not be obstructed. See Figure 1-1.
2.4 INPUT
WIRING
The AC Power System must be operated from a three-wire three-phase service with a fourth wire for common. The
common wire is connected to the chassis of the AC Power System. The mains source must have a current rating
greater than or equal to the AC Power System circuit breaker, 40 amps. Refer to Figure 2-1 for the input power
connections. Refer to Figure 2-2 for all multichassis power systems.
The 2750L may also be operated from a 1-phase input. The 1-phase line input must be connected between the øB and
øC terminals of TB3 on the rear panel. These terminals are identified as terminals 2 and 3 of TB3 in Figure 2-1.
