and these instructions when wiring.
Improper connections and inadequate grounding
can cause
accidental injury or death
.
z
This controller is strongly recommended to be
installed with Earth Leakage Circuit Breaker
(ELCB) or Residual Current Device (RCD).
Otherwise, it may cause electrical shock
and re in case of equipment breakdown or
insulation breakdown.
Earth Leakage Circuit Breaker (ELCB) must be
incorporated in the xed wiring in accordance
with the wiring regulations. The Earth Leakage
Circuit Breaker (ELCB) must be an approved
10 A, having a contact separation by 3 mm in
all poles.
z Provide a power outlet to be used exclusively
for this controller.
z Turn off the circuit breaker of the controllers
before installation.
z
Do not supply power to the controller until all
wiring is completed or reconnected and checked.
z Fix the power supply wiring securely with the
clamper so that the power supply terminal
board is free of tension (external force) when
pulled. Loose connection of the terminal
board may cause re.
