SAFETY PRECAUTIONSThe controller described in this manual consists of electric parts and units. To prevent accidents and also failure and burning of electric parts and units due to improper interconnection ofthem and also connection of power cables, please read the manual carefully and strictly observe the itemsindicated below.

(1) Before connecting or disconnecting/removing a unit, shut off all power supplies and discharge parts inunits which have been charged. Otherwise, injury, or failure or burning of a unit may occur.

(2) Check the specifications of the power supply to be connected. Failure or burning of a unit may occur ifpower supply voltage does not match the power requirements of the unit or if the polarity is incorrect.

(3) Connect inputs and outputs of a unit correctly. If they are connected incorrectly, failure or burning of a unitmay occur.

(4) Always ground units and connect the P.E. earth cable of the electric cabinet. Otherwise, electric shockmay cause if leakage occurs.

(5) Insert an over current protection device (breaker, fuse) to the power supply which is connected to units.Otherwise, cables or units may be burnt or fire may be cause due to short circuit.

(6) When manufacturing cables used for connecting units, make sure that the size of cables matches thecarrying current. Especially, power cables must be manufactured carefully. If the current capacity of thecable is insufficient, the cable may be heated to be burnt or fire may be caused.

(7) The electric cabinet and the operation box where units are installed must be water-and dust-proofconstruction. Otherwise, injury, or failure or burning of a unit may occur.

(8) Make sure to use a thermostat incorporated in motors and units to protect devices. Otherwise, devicesmay be burnt or fire may be caused.

4. CautionsThe drip-proof bushing of MIV06, MIV08, or MPS10 used for the machine delivered before June1999 is fixed with silicone rubber for the enhancement of water tightness of the motor cable port ofthe external cooling fan. (Sufficient water tightness has been verified without silicone rubber andsilicone rubber is not used now.)For this reason, silicone rubber must be removed at the above-mentioned drip-proof bushing duringreplacement using sand paper or the like. (If old silicone rubber remains, water tightness maydeteriorate substantially after replacement.)
