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.
