Electrical Operating Conditions
Transients
The general purpose switch modules described in this manual are designed to
safely withstand occasional transient voltages up to 1500 Vpeak. Typically, these
transient overvoltages result from switching inductive loads or from nearby
lighting strikes.
High Energy Sources
These modules are designed to handle inputs up to their rated currents or their
rated powers, whichever is less. Under certain fault conditions, high energy
sources could provide substantially more current or power than a module can
handle. It is important to provide external current limiting, such as fuses, if the
module inputs are connected to high energy sources.

.
To avoid electric shock, Turn off the chassis and disconnect
or de-energize all field wiring to the modules before
installing or removing any module or chassis slot cover.
Not for connection to mains. Do not connect any of the
modules directly to a mains power outlet. If it is necessary
to switch a large inductive load, you must add signal
conditioning elements to reduce the potential transients
before they reach the modules.
Install current limiting devices between high energy sources and
the module inputs.
