(Note 1) The total length of the SH21 cable must be within 30m.
(Note 2) The connection method will differ according to the used motor.
(Note 3) When not using a battery unit, connect the terminal connector (R-TM).
(Note 4) The main circuit (
) and control circuit ({) are safely separated.

1. Always use one AC reactor per power supply unit. Failure to observe this
could lead to unit damage.
2. When sharing a breaker for several power supply units, of a short-circuit
fault occurs in a small capacity unit, the breaker could trip. This can be
hazardous, so do not share the breaker.
CAUTION
3. Be sure to use the breaker of proper capacity for each power supply unit.

CAUTION
Do not apply a voltage other than that specified in Instruction Manual on each
terminal. Failure to observe this item could lead to rupture or damage, etc.
