Chapter 2 — Installation and Wiring
Operator Safety Instructions and Symbols
It is very important that these safety instructions and operation instructions are read and
understood prior to the installation and use of this electronic load. Failure to follow these basic
guidelines could result in serious injury or death.
This electronic load is inherently safe by design. It cannot produce any hazardous voltages or
currents; however, when in use it may expose the operator to the hazards of the DC source to
which the load is connected. This equipment is intended for use by trained personnel and there
are no operator serviceable parts inside. All service and calibration must be performed by
authorized personnel. Table B describes the safety symbols and their definitions. Safety symbols
are placed to ensure the safety of Dynaload operators and should never be covered or removed
from the equipment.
WARNING:
Ensure that all AC and DC power for both the load, the test source, and any
peripheral equipment are OFF prior to making any connections to the load.
Also ensure that the proper AC input range is selected before attaching the
line cord; and that the load selected is properly rated for the voltage and
current generated by the DC source; and that all connections are correct
and secure, and that all safety covers are in place before applying power.
If the unit is to be mounted, please consider the weight and position of the
equipment to prevent the rack from becoming top heavy. A top-heavy rack
can create a tip over hazard. All air intake and exhaust ports should be kept
clear of obstructions.
