* Installation of transient suppressors across the coils of
FSD1 and FSD2 is recommended. NOTE: Do not exceed
OSSD maximum load capacitance specification.

WARNING . . .
Proper Wiring
The generalized wiring
configurations shown are provided
only to illustrate the importance of
proper installation.
The proper wiring of the EZ-
SCREEN Grid System to any
particular machine is solely the
responsibility of the installer and
end user.

CAUTION. . .
Shock Hazard
Always disconnect all
power from the EZ-SCREEN System
and the guarded machine before
making any connections or
replacing any component. Use
extreme caution to avoid electrical
shock at all times.
Serious bodily injury or death
could result.
WARNING . . .
OSSD Interfacing
To ensure proper
operation, the EZ-SCREEN OSSD
output parameters and machine
input parameters must be
considered when interfacing the EZ-
SCREEN solid-state OSSD outputs
to machine inputs.
Machine Control circuitry must be
designed so that the maximum load
resistance value is not exceeded
and that the maximum specified
OSSD OFF-state voltage does not
result in an ON condition.
Failure to properly interface the
OSSD outputs to the guarded
machine could result in serious
bodily injury or death.
