UNPACKING AND INSTALLATION
2.1
UNPACKING
After unpacking the inverter (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 / WIRING
1)
This unit is designed to be rack mounted in a standard EIA 19" cabinet but can be operated in
any location. It is preferable to operate in a location which will maintain air temperature of 0-55°C
around the ventilation ports. Therefore if the unit is to be rack mounted, it is recommended that
the enclosure be forced ventilated or air conditioned. Installation should insure that the side and
rear vents are unobstructed.
IMPORTANT
NOTE
:
The unit must have bottom support when mounting in a rack or cabinet. Do not attempt to mount
by front panels only. Chassis slides or mounting angles are available for this purpose. Consult
with the Behlman sales department.
2)
Ensure that the line circuit breaker is in the OFF position before connecting input power.
3)
Connect input/output power lines as follows:
WARNING
Ensure that input line and neutral are connected to proper AC input terminals. A protective
earth connection is required for operator safety and EMI filter return currents. Do not
operate without this connection.
a)
INPUT POWER- Is connected to the appropriate terminals on the unit's rear panel. (See
figures 2-1 & 2- 2). The proper size of input wiring is determined by the wire length and
current to be carried. The following table lists suggested wire size for lengths up to 50
feet. Longer lengths
should use larger diameter wire.
