Chapter 3 Setting Up the Instrument
To connect a cable to a terminal block, lift up the cover at the front and then con-
nect the cable to the terminal block.
1. Loosen the screw at the bottom of the cover with the Phillips screwdriver
and lift up the cover.
2. Loosen the screws of the terminal block, connect the input cable, and then
tighten the screws.
The connection method differs depending on the measurement object. See the
next page.
3. Reattach the cover, and tighten the screw.
Tighten the screw to no more than 0.6 Nm.
3.2.2 Connecting a Cable
• In order to prevent electric shock and short-circuit accidents, shut off the power
to the line to be measured before connecting the input cable.
• To avoid electrical accidents, confirm that all connections are secure. The
increased resistance of loose connections can lead to overheating and fire.
• Channels are isolated by semiconductor relays. Never apply a voltage in
excess of the specifications between channels as doing so could damage the
semiconductor relays by causing them to short out. Exercise particular care
concerning surge protection against lightning and other threats. If the instru-
ment yields erroneous measured values, have it inspected.
Be sure to pull out an input cable after you loosen the screws of the terminal
block. The input cable will be damaged if the screws are not loosened and
excessive force is used to pull out the input cable.
