1. Precautions Regarding Installation
When installing the equipment and performing the instrumentation work, take due care of the
following precautions.
1. When performing the grounding work, connect the ground wire to the ground terminal
inside the panel. Use wire with a diameter equal to or larger than the power supply wire
(AWG-12).
2. Do not install an overcurrent circuit breaker in the grounding wire.
3. Install an independent ground fault circuit breaker (with overcurrent protection) within 10 ft
(3 m) of the node point in the low-voltage interior wiring.

4. Install a ground fault circuit breaker (with overcurrent protection) for each phase (L phase
and N phase).
5. Use a power supply wire with insulation resistance of 0.1 MΩor higher.
6. Use AWG-12 wire or larger diameter for the power line. Protect the wire in a conduit.
7. Protect the steam pressure sensor and steam pressure switch wires in a conduit.
8. Ensure that the total length of each wire for the steam pressure sensor and steam
pressure switch is within 165 ft (50 m).
9. Limit the wire length between the hub and equipment to 330 ft (100 m) or less.

4. Carrying
• See the overall view for the dimensions.
* The BP-201STA is packaged in bubble wrap.
• Take care not to impart shocks during carrying the BP-201.
5. Installation
5.1 Precautions when Installing the Main Unit
• Install in a location within the equipment operating environment range (temperature and
humidity).
• Avoid the following locations, which may cause equipment failure.
1) Locations subject to direct sunlight or near equipment that generates heat
2) Hot locations or locations with large temperature fluctuations
3) Locations with high levels of moisture or dust
4) Locations subject to shocks or vibrations
5) Locations in a chemical atmosphere, or locations that may contact chemicals or water
6) Locations near power lines or near equipment that generates strong magnetic fields
7) Locations subject to severe supply voltage fluctuations
CAUTION
Wear protective equipment when carrying the BP-201.
BP-201STA: Up to approx. 132 LB (60 kg) (depending on options)
CAUTION
Observe the following precautions about installation and ensure that
the BP-201 is installed in an appropriate location. Installation in an
inappropriate location may result in equipment failure.

Document Control #: 001157

All copies of the document are uncontrolled when printed
• Firmly fix the BP-201 in a location that is free of vibrations.
• Install in a location free of water and condensation.
• During installation, do not touch any of the internal circuit boards. Do not allow dust or
metal fragments to enter inside the BP-201 main unit.
• The maximum wire length between the BP-201 and the steam pressure sensor or steam
pressure switch must not exceed 165 ft. Install the BP-201 in a location where the wires
can reach.
• Ensure adequate space to open the door for adjustment or maintenance work.
• The BP-201 is designed for indoor installation. When installing it outdoors, take
appropriate measures to protect against water, dust, and freezing, and select a location
that is not subject to direct sunlight.
CAUTION
Do not directly weld the box onto a column or wall. The BP-201
contains electrical equipment that may be damaged by the effects of
arc welding.
CAUTION
The holes in the top of the main unit are covered by seals. Remove
the seals only from the wiring hole that is used. Leaving wiring holes
open allows condensation to flow down the wires and into the
equipment.

5.3 Precautions when Installing the Steam Pressure Sensor and
Steam Pressure Switch
• Install the steam pressure sensor and steam pressure switch to the steam header
collecting the steam from each boiler.
• Connect the steam pressure sensor and steam pressure switch at a location remote from
the steam outlet piping.
• Install the steam pressure sensor and steam pressure switch in vertical pipes.
• Place in a location free of water vapor and condensation.
• Connect the wiring such that water cannot flow along pipes or wires into the steam
pressure sensor and steam pressure switch.
• Use a syphon tube to adequately cool the piping to the steam pressure sensor and
steam pressure switch. The pressure-receiving parts should not reach 176°F (80°C).
• Do not allow wires to contact hot parts such as the steam header.
Figure 5-1: Example of steam pressure sensor and steam pressure switch installation
CAUTION
Do not install a pressure-reducing valve, accumulator, or other device that
changes pressure between the boiler and the steam header on which the
steam pressure sensor and steam pressure switch are installed.
If a device such as a pressure-reducing valve or accumulator is used,
install the steam pressure sensor and steam pressure switch between the
boiler and the device.

6. Wiring Work
6.1 Precautions
(1) Wiring power supply line and installing ground fault circuit breaker (with
overcurrent protection)
• Use power supply wire AWG-12 or larger and round crimp-type terminals.
• Connect the grounding phase of the power supply line to the N phase. Always
ground the equipment ground terminal using a wire of the same or larger diameter
than the power supply wire.
• Install a ground fault circuit breaker (with overcurrent protection) in the BP-201
power supply line.
• When installing the ground fault circuit breaker (with overcurrent protection), do not
connect the overcurrent circuit breaker to the grounding wire.
(2) Wiring signal line
• See “6.4 Wires and Terminal Processing” for details about wires used for the signal
line and terminal processing.
• Separate the communication wires, sensor wires, and I/O signal wires from power
wires and power supply wires and do not pass them through the same conduit. Do
not pass wires next to high-output equipment that generates strong electrical or
magnetic fields, such as a machine tool.
• To mark the wiring, use stamped marking tubing or marking bands.
• Connect the wiring such that water cannot flow along pipes or wires into the main
unit.
(3) Frame grounding of flowmeter
• Connect the shield of the shielded cable used with the flowmeter to the terminal E
on the terminal block.
