WARNING

To avoid an electric shock or damage to the equipment, always observe the

following precautions when connecting your external equipment to external

control terminals.

• Always turn off the instrument and any equipment to be connected before

making connections.

• Be careful to avoid exceeding the ratings of the external control terminals.

• Properly isolate the devices and systems to be connected to the external

control terminals from one another.

Always turn both devices off before connecting and disconnecting an interface

connector. This may cause an electric shock.

CAUTION

• Use a common ground to both the instrument and the connected equipment. Using

different ground circuits will result in a ground potential difference between the

instrument and the connected equipment. If the communications cable is connected

while such a potential difference exists, it may result in equipment malfunction or

failure.

• Before connecting or disconnecting any communication cable, always turn off the

instrument and your device to be connected. Failure to do so could result in an

equipment malfunction or damage to the equipment.

• After inserting the connector, securely tighten the screws of the connector. Failure to

do so could result in an equipment malfunction or damage to the equipment.

• To prevent damage to the equipment, use the recommended type of wires to connect

your external equipment to the external control terminal, or otherwise ensure that the

wires have sufcient withstand voltage and current capacity.

Refer to “2.3 Connecting the External Control Terminals” (p. 53).
