F.3 DON'Ts
DON'T APPLY DIRECT VOLTAGE TO DIGITAL INPUTS
There are 6 switch inputs on the 269Plus; Spare, Speed, Differential, Access, Emergency Restart, and Exter-
nal Reset. These inputs are designed for dry contact connections only. By applying direct voltage to them may
result in component damage to the Digital input circuitry.
DON'T RESET 86 LOCKOUT SWITCH BEFORE RESETTING RELAY
DON'T Reset an 86 Lockout Switch before resetting the 269Plus.
If an external 86 Lockout device is used and connected to the 269Plus, ensure that the 269Plus is reset prior
to attempting to reset the lockout switch. If the 269Plus is still tripped it will immediately re-trip the lockout
switch. Also, if the lockout switch is held reset, the high current draw of the lockout switch coil may cause dam-
age to itself and/or the 269Plus output relay.
DON'T INSTALL WIRING CLOSE TO HIGH VOLTAGE AND CURRENT CARRYING CONDUCTORS
Although the 269Plus circuitry is internally shielded to minimize unwanted noise pickup and interference,
ensure that any high voltage/current carrying conductors or sources of strong electromagnetic fields are
directed away from the 269Plus or any of its input/output wiring such as control power, phase and ground CTs,
RTDs, digital inputs and output relays.
