1. SAFETY SUMMARY
ÕWARNING:
-This product is used for BMS connection adapter for HITACHI Water Chilling Units.
-Do not place the adapter in a place where flammable gas, or oil mist may stay exit, it will
cause a fire, a fire disaster, deformation of machines, corrosion or breakage
-a place where oil mist or steam drifts.
-a place where sulfide gas form as hot spring drifts.
-In the case that a medical equipment generating electro-magneticwaves is installed near
the Water Chillers, pay an attention to the radiation direction does not occur.
-It is recommended that a space of 3 m or more between HARC70-CE and the medical
equipment, radios, etc. be provided.
-Do not place the adapter in a place to be exposed to direct sunlight.
-Install action:
-Install properly this adapter by following this manual to avoid any electric shock, fire
disaster and injury by falling down HARC70-CE1.
-Check to ensure that the adapter is fixed firmly to avoid injury by falling.
-To avoid the fire or fire disaster, do not install the adapter in a place where there is
possibility of generation or flow of flammable gases.
-Electrical Work:
-To avoid any electric shock, ask for the work to the shop having qualification for
electrical works.
-To avoid any electric shock and disaster, perform electrical wiring according to local
regulations.
-To avoid electric shock, and fire disaster, use the prescribed cable to connect of Water
Chiller units, (model HARC70-CE1)
-Turn off electrical power before electric wiring work when the cover of HARC70-CE1
is opened.
