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 . . .
Use of Transient
Suppressors
If transient suppressors are used,
they MUST be installed across the
coils of the machine control
elements. NEVER install
suppressors directly across the
contacts of the IM-T-..A Module! It
is possible for suppressors to fail as
a short circuit. If installed directly
across the contacts of the IM-T-..A
Module, a short-circuited
suppressor will create an unsafe
condition.
!
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.
