Power supply specifications, power supply cable and earth leakage breaker
Prepare the power supply shown in the following table. For the connection between the product and
power supply, use the power supply cable and earth leakage breaker shown below. An earth leakage
breaker must be mounted to a position where the breaker is easily accessible and close to the
thermo-chiller.

*1. A specified earth leakage breaker is installed for option B, option B1, option S of each model. If
the product is not option B, option B1, option S, please prepare an earth leakage breaker on the
user’s side. A specified earth leakage breaker and handle are installed for HRSH--40-
*2. Cable specifications are the examples when using the product at a continuous allowable
operating temperature of 70
o
C, with an operating voltage of 600 V and two kinds of plastic
insulated wires at an ambient temperature of 30
o
C. Please select the proper size cables
according to the actual condition.
Installation/operation in accordance with the UL standard (for the optional UL
compliant model)
For operation of the UL compliant model (available as an option, HRSH--20-S) in the UL
compliant conditions, the conditions shown below must be satisfied:
- Use power supply of overvoltage category 2 (transient overvoltage 2500 V
or less)
*1
.
- Bending radius of the power supply cable must be 38.1 mm or more.
*1. When using a power supply in the overvoltage category 3, take measures such as mounting an
isolation transformer between the product and the power supply or keep the transient
overvoltage of the power supply to 2500 V or less by using a varistor, etc.
