SAFETY PRECAUTIONS
There is always a danger present when using electronic equipment.
Unexpected high voltages can be present at unusual locations in defective
equipment and signal distribution systems. Become familiar with the equipment
that you are working with and observe the following safety precautions.
•Every precaution has been taken in the design of your IMPULSE 400D to ensure
that it is as safe as possible. However, safe operation depends on you the
operator.
•Always be sure your equipment is in good working order. Ensure that all points
of connection are secure to the chassis and that protective covers are in place
and secured with fasteners.
•Never work alone when working in hazardous conditions. Always have another
person close by in case of an accident.
•Always refer to the manual for safe operation. If you have a question about the
application or operation call Sencore for assistance.
•WARNING –To reduce the risk of fire or electrical shock never allow your
equipment to be exposed to water, rain or high moisture environments. If exposed
to a liquid, remove power safely (at the breaker) and send your equipment to be
serviced by a qualified technician.
•To reduce the risk of shock the IMPULSE 400D must be connected to a mains
socket outlet with a protective earthing connection.
•For the IMPULSE 400D the mains plug is the main disconnect and should remain
readily accessible and operable at all times.
The IMPULSE 400D is equipped with an internal system battery. The IMPULSE
400D must be sent to Sencore service for replacement of this battery.
•When installing the IMPULSE 400D utilizing the DC power supply, the power
supply MUST be used in conjunction with an over-current protective device rated
at 50V, 5A, type: Slow-blo, as part of battery-supply circuit.
•To reduce the risk of shock and damage to equipment, it is recommended that the
chassis grounding screw located on the rearof the IMPULSE 400D –be connected
to the installation’s rack, the vehicle’s chassis, the battery’s negative terminal,
and/or earth ground.
CAUTION –Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type.

2.1 Rack Installation
To install the IMPULSE 400D into a rack use the following steps:
1. Determine the desired position in the rack for the
IMPULSE 400D making sure that the air intake on the
front of the unit and the exhausts on the sides of the
unit will not be obstructed.
2. Insert the rack mount clips into place over the
mounting holes in the rack.
3. Slide the IMPULSE 400D into position in the rack.
4. Secure the IMPULSE 400D to the rack by installing the
four supplied screws through the front mounting holes
and tightening.
5. If needed, secure a grounding wire use the grounding
location on the rear panel of the IMPULSE 400D. See
Section Error! Reference source not found. for
grounding location.
2.2 Power Connection
Using the proper power connections is vital to the safe operation of the IMPULSE
400D. Only use the supplied 3-prong power connector or one with equal specifications.
NEVER tamper with or remove the 3rd –prong grounding pin. This could cause
damage to the IMPULSE 400D, personnel, or property.
2.3 AC Power Connection
The IMPULSE 400D is intended for use on either 120V or 240V systems. The power
supply will automatically detect the system it is connected to. To hook up the power
use the following steps:
1. Locate the AC power cord that was included with the IMPULSE 400D.
2. Plug the female end of the power cord (end with no prongs) into the back of the
unit.
3. Locate a protected outlet (usually inside of the rack) to plug the male end of the
power cable into.

Impulse 400D –User Manual
Page 15 (87)
2.4 DC Power Connection (optional)
The IMPULSE 400D with the DC chassis option is intended for use on 48V DC
systems. A power cable is not included for this option. In order to apply power to the
unit in this configuration, simply connect the screw terminals on rear of the unit to the
rack’s DC power rails.
Be sure that the power source and cable is used in conjunction with an over-current
protective device rated at 50V, 5A, type: Slow-blo fuse as part of battery-supply circuit.
Also, to reduce the risk of shock and damage to equipment, it is recommended that
the chassis grounding screw (1.3) located on the rear of the IMPULSE 400D –be
connected to the installation’s rack, battery negative terminal, and/or earth ground.
2.5 Maintenance
The IMPSULE 400D is virtually a maintenance-free piece of equipment. There are no
user serviceable parts on the inside of the unit

The IMPULSE 400D can be setup on a network connection to allow remote
management and SNMP configuration. For these features to work, the network settings
for the IMPSULE 400D must first be configured properly for the network it is connected
to.
