E1 (+)
• Terminals 12 and 41 are connected internally. When connecting
• Connect terminals 21 and 22 and terminals 51 and 52 in series
• In the following connection example, terminals 21 and 22 and
• Direct opening contacts used as safety-circuit inputs are indicated
• Connect the indicators in parallel to the auxiliary circuits or
• Do not switch circuits for two or more standard loads at the same
• DC solenoids have polarity. Confirm terminal polarity before wiring.

when using as safety-circuit inputs (redundancy circuit for
terminals 11 and 12 and terminals 41 and 42 below). Connect the
terminals individually when using as auxiliary-circuit inputs (e.g.,
terminals 21 and 22 for safety-door open/closed monitoring and
terminals 51 and 52 for monitoring the lock status).

Connecting to contacts with direct opening mechanisms may result
in short-circuit current flowing if the indicator is destroyed, possibly
resulting in incorrect equipment operation.
