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
!
IMPORTANT
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 assembled in an EIA standard rack cabinet. It consists of a removable control chassis and
integral DC power supply. Connections to the DC supply are factory provided. External connection are
made through an access hole located at the bottom rear of the cabinet. The installation site must
provide proper cooling air circulation. Cool air is drawn in through the rear of the control chassis and
heated air is exhausted out of the lower exhaust fan mounted to the rear door. The cabinet rear door
must be installed and closed during normal operation. Door Locks and keys are provided for safety.
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 blocks.
Turning or removing the upper screws will loosen internal hardware and will cause damage to the unit.
4)
All wiring should enter through the access hole in the bottom rear of the cabinet. Strain relief and
mechanical protection for wiring must be supplied by the end user. 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 rear panel terminals designated ,
N
A,
N
B,
N
C, and neutral ( required for all inputs above 240V L-N ) on the AC INPUT
terminal block at the bottom of the power chassis. Re-install all provided safety covers.
b)
OUTPUT POWER- Output power lines are connected to designated terminals,
N
A,
N
B,
N
C,
and neutral provided on the control chassis ( or on the output chassis supplied with “T”
option). Refer to figure 2-1. Re-install all provided safety covers.
c)
Interconnection between chassis:
Standard units have hardwired DC connections and are factory connected to the control
chassis.
d)
On all units, a chassis mounted stud is provided to connect a protective 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-x . Consult local codes and a licenced electrician.
