Request
Please ensure that this instruction manual is provided to the final user of the apparatus.
Introduction
This instruction manual is meant for those who will be involved in wiring, installation, operation and routine
maintenance of the HB20.
As this manual describes matters to be attended to in its operation, wiring and installation, you are requested to
keep this manual at your work site when using the apparatus. You are also requested to follow the instructions
provided herein.
For matters concerning safety, potential damage to equipment and facilities, additional explanation and instructions
are given under the following heading:
WARNING:
Indicates that failure to follow instructions could cause injury or even death.
CAUTION:
Indicates that failure to follow instructions could cause damage to equipment and/or facilities.
WARNING
1. This apparatus must be housed, for example, in a control box to prevent the terminal board from coming into
accidental physical contact with personnel.
2. Wiring should be carried out without energizing the apparatus. Otherwise, an electric shock is probable.
3. Once wired, do not touch the terminals or other charged parts while they are energized.
CAUTION
1. The alert mark on the plate affixed to the apparatus:
On the nameplate affixed to the case of the apparatus, the alert mark is printed. This is to warn you of an
electric shock which may result if the charger is touched while it is energized.
2. A means to turn power off, a switch or a breaker, should be installed in the external power circuit to be
connected to the power terminals of this apparatus.
3. Note on Fuse
This apparatus has no built-in fuse. Install a fuse in the power circuit to be connected to the power terminals.
(0.5A, normal blow type)
4. In wiring, terminal connectors should be fastened properly.
5. Use power voltage and a frequency respectively within the ranges of their ratings.
6. Do not apply voltage and current which are out of the ranges of their ratings to the input terminals. Such an act
may shorten the life of the product or cause trouble with the apparatus.
7. In case the system is equipped with output terminals, current and voltage of a load to be connected to the
output terminals should be within the ranges of their ratings. If their ratings are exceeded, a rise in
temperature may shorten the life of the product or cause trouble with the apparatus.
8. Be sure to cut the power supply OFF before pulling the apparatus out of its surface socket. Especially in case
of using with an external CT, CT may be burnt out by pulling it out.
9. Users are prohibited from remodeling the apparatus or using it in an unauthorized manner.
10. You are requested to adhere to the matters to be attended to as described in the instruction manual in order to
use the apparatus safely and correctly and to maintain its reliability.
Note: For accidents or damage arising from failure to observe "
instruction manual, we will take no responsibility nor provide compensation.
