HB21 Heater Breakdown Detector (Usable for Phase-Control Circuit)
Thank you for purchasing the Shimaden HB21 Heater Breakdown Detector. Please check that the delivered
product is exactly what you ordered, referring to the list of model codes shown below and use it correctly as
specified in the following instructions.
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 HB21.
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 This heading indicates that failure to follow instructions could cause injury or even death.
This heading indicates that failure to follow instructions could cause damage to equipment and/or facilities.
CAUTION
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.
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.
