Power Wiring
- This LR/HR series pump is locked out in intercepting cooling water, the N2 gas,
and the power line. Give the system which can lock out on the host equipment.
- Material selection, installation and operation of wiring should be done
according to the rules and codes applied in your country (e.g. fire fighting law,
electric installation code, etc).
- For serious situations such as abnormal current or voltage, the products are
provided with safety devices (e.g. noise filter) with which these abnormal
situation can be avoided. To release the leaking current securely, the power
wiring (cable terminal of the host equipment) should be directly connected to
the terminal board (breaker).
- Though these products are provided with breaker (MCB1, MCB2 (LR/HR300,
LR/HR600, LR/HR1200, LR/HR1800, LR3600)), inner wiring from power
connector through the breaker (MCB1, MCB2) is keeping hot. To completely
shutoff the electricity, provide a breaker (M/D: AIC 10kAV or above) to the host
equipment.
- Heater (AC200V) is installed in the exhaust pipe. Obtain the protection cover
according to “finger safe” which are the rule and the law concerning safety in
the country.
- When to perform installation or removal of these products, the power should be
shutoff completely according to the following diagram.
Current value at the maximum load and inverter and driver’s INPUT current are shown
in the following (current which flows to inverter and driver immediately after turning on
of power supply).
Please select the electric wire, which the electric wire specification can be allowed referring
to current at the maximum load.
Please confirm that the size of the electric wire is a size of the electric wire, which the
connector can be allowed.
