4 INSTALLATION AND START UP
4.1 INSPECTION
The DC Injection unit has been packaged to protect it from damage caused by normal
handling during shipping, however mishandling may cause damage to the DC Injection unit.
Unpack the unit as soon as it is received and check for any shipping or storage damages. If damage
is found notify the carrier. Any damage claim must be filed by the customer since all shipments
are F.O.B. Cutler-Hammer plant unless otherwise specified.
If the DC Injection unit is not installed when received, store it in a clean, dry, well ventilated
area, free from heat, humidity, oil, dust and metal particles.
4.2 SAFETY PRECAUTIONS
Equipment is at line voltage when AC power is connected. Pressing "STOP"
pushbutton does not remove AC mains potential. All phases must be disconnected
before it is safe to work on machinery or touch motor terminals or control
equipment parts.
Disconnect incoming voltage from unit before opening load side during DC
injection. Failure to observe this precaution can result in damage to disconnecting
device and/or bodily injury.
The electrical code requires all equipment, starter motor, operator station, brake, etc... to be
grounded properly. An incoming circuit breaker or disconnect switch must be locked open
before wiring and servicing this electrical brake, motor, or other related equipment. This
equipment must be installed and serviced only by qualified personnel, familiar with this unit.
The user is responsible for ensuring that proper short circuit protection is provided by either a
circuit breaker or HRC fuses.
4.3 MOUNTING GUIDELINES
Standard Nema 1 DC Injection units must be installed indoors in a well ventilated area,
free from heat, humidity, oil, dust and metal particles.
One foot of clearance must be kept around the perimeter of the unit in a naturally cooled
setup. The equipment must be mounted away from any heat source. See Section 2 for
additional specifications and derating. Be aware that the heatsink may reach temperatures of
70°C / 158°F during normal operation. Do not install the unit in contact with any material
that can not accept this temperature.
The DC Injection Unit must be mounted vertically and where it will not experience excessive
shock or vibration.
