Use a Power Supply with an Isolating Internal Protection Circuit
− Use an isolating power supply that incorporates an internal protection circuit in order
to protect against abnormal voltages coming from the electric lines.
− The controller regulator is non−isolated.
− When using an electrical device that does not have an internal protective circuit be
sure to supply electric power to the controller only after passing it through a fuse or
other protective element.
Switch the power on and off at the primary side.
− Switch the power on and off at the primary side (100 V AC). If you switch the power
on and off at he secondary side (24 V DC), you can cause the fuses to blow.

Use a power supply that has sufficient surplus capacity!
− When you first switch the power on, the temporary in−rush current far exceeds the
rated current. Therefore, be certain to use a power supply that has sufficient surplus
capacity to handle this (i.e. rated at about three times the steady−state current), and
test it to ensure that it operates correctly.

24 V DC electric power is supplied by attach-
ing wires to the input terminal block's (+) and
(–) terminals and to the ground terminal (frame
ground).
Twist the electric wires in order to reduce the
effects of noise.
