• Avoid leaving the battery in high tem-

perature places such as direct sunlight,

inside a sun-heated car, near water, or

near a heater. Doing so may cause

battery leakage, or reduce the battery

functions and lifetime.

• The battery can be recycled. To recycle

your used battery, follow the regula-

tions and instructions in your area.

External Interfaces

• This PL unit’s serial port is not isolated.

When the host (PLC) unit is also not

isolated, and to reduce the risk of dam-

aging the RS-232C/RS-422/RS-485

circuit, be sure to connect pin #5 SG

(Signal Ground) terminal.

• Never connect NC to COM1.

• Connect FG to housing.

• COM2 is not available on the built-in

battery unit version because that ver-

sion uses COM2 exclusively as an

interface for battery output.
