SECTION 2
UNPACKING AND INSTALLATION
2.1 UNPACKING
After unpacking the AC Source (unit), carefully conduct a thorough inspection of controls, indicators and
chassis. If the unit shows signs of damage, do not attempt to operate. File a damage claim with the carrier
responsible. Notify Behlman immediately.
2.2 INSTALLATION
! WARNING
1) This device must be installed and operated by qualified persons only. The content of this manual
must be reviewed prior to use.
2) This unit is designed to be rack mounted. The unit must have bottom support when mounting in a rack
or a cabinet. Do not attempt to mount by front panels only. These units, when stacked, require proper
cooling air circulation, one inch clearance between units and a six inch clearance at the rear of the
units.
3) Ensure that the line circuit breaker and all other unit controls are in the OFF position before connecting
input power. Use
only the lower screws when connecting wires to the control chassis terminal block.
Turning the upper screws will loosen internal hardware and may cause damage to the unit.
4) Connect 3 phase units as follows: ( refer to inter-connect diagrams provided on following pages.)
a) INPUT POWER- Connect 47-63 Hz, power lines to the designated terminals, N A, N B, N C,
and Neutral ( required for all inputs above 240V L-N ) on the INPUT terminal strip of the
power chassis. See additional info for single phase inputs.
b) OUTPUT POWER- Output power lines ( load ) are connected to the N A, N B, N C, and
Neutral provided on the AC OUTPUT terminal strip of the control chassis. For T option units
the load is connected to the AC OUTPUT optional transformer chassis.
c) Interconnection between chassis:
Connect HI, GND, and LOW of power chassis to HI, GND, and LOW of control chassis with
cable provided. Connect the two chassis together by connecting their GND studs with cable
provided. Units supplied with rack cabinet are inter-connected at the factory .
d) On all units, a chassis connected stud is provided to connect a safety earth to each metal
chassis.
This connection is required to provide operator safety and reduce EMI emissions.
!
IMPORTANT NOTE:
If this unit is to be installed as part of a permanent power source with wiring distributed in a building the
user is responsible for conformance to local electrical codes . The National Electrical Code (NEC),
section 250 , requires that all separately derived AC power sources ( generators, inverters, etc.) must
have one conductor tied to earth. This is similar to the concept of the neutral conductor in domestic
power distribution systems. This connection may be provided by connecting the input neutral to the
output neutral or connecting the output neutral to the chassis ground ( assuming the chassis is tied to
earth). See figure 2-4 . Consult local codes and a qualified electrician.
