• To minimize the in fl uence of noise on the output, use a 2-core
shielded wire or a twisted-pair wire to connect the control ter-
minals and Rext. If using a shielded wire, connect the shield
to the + (pos.) output terminal.
Note that longer lengths of wiring result in more susceptibil-
ity to the effects of noise; use of cables with anti-noise mea-
sures may not solve the problem.
• Approx. 1 mA of current always fl ows in Rext. For Rext, use
a 1/2 W or larger metal fi lm or wire-wound type resistor with
a good temperature coef fi cient and small aging effect.
5. Re-check that the connections on the terminal board and
the switch settings are correct.
Before controlling output voltage using the external resistor, re-adjust
the voltage system of the unit. For the adjustment procedure, see "6.3
Adjustment".
