Page 6 Safety Precautions WARNING Do not use this device in an environment with conductive pollution, or with dry non- conductive pollution which can become conductive due to condensation, etc. Otherwise, problems such as tracking phenomena may damage parts, resulting in fire. When wiring the power for this device, be sure to mount a shutoff switch for the main power to this unit within reach of the operator.
Page 7 CAUTION There is no isolation between control outputs 1 and 2. When necessary, use an appropriate isolator. Do not connect multiple loader cables to multiple units from one personal computer. The current coming from other circuits might cause an error in the indication of the PV. When wiring RS-485 communications, do not connect a terminating resistor to either end of the communication path.
