Safety Precautions

•

Do not perform any electrical wiring while electric current is applied. Failure

to follow this may result in an electric shock or fire.

• Be sure to connect the grounding cable. Failure to follow this may result

in an electric shock or fire.

• Do not touch this unit within 1 minute after AC input is turned off. Failure

to follow this may result in an electric shock.

• Do not modify or repair this unit. Failure to follow this may result in an

electric shock, accident, or product failure.

• Do not touch any terminal of this unit while electric current is applied.

Use the unit with the terminal cover installed to avoid an electric shock.

• When this unit is used in a system that may cause a serious accident or

damage if the unit fails, be sure to install a safety device.

• Pay attention to prevent foreign matter such as metal particles, dust,

paper or wood chips from entering the inside of this unit. Failure to

follow this may result in a fire or product failure.

• Do not touch any metallic part while electric current is applied or

immediately after input is shut off. Failure to follow this may result in a

burn due to a high temperature.

• If a failure or abnormality occurs while this unit is in use, immediately

such off AC input and stop operation of this unit . Failure to follow this

may result in a fire or accident.

• Check that the AC input rated voltage of this unit is equal to the voltage

of the AC power supply.

• Do not connect the AC power supply to the DC output terminals.

• Do not disturb the convection of air near the vent of the casing.

■ Precautions for CE Markings

KEYENCE has evaluated the conformity of the MS2 Series with the requirements of the EMC

Directives and Low-voltage Directives under the following condition, and confirmed that the MS2

Series meets these requirements. For the Low-voltage Directives, the MS2 Series has obtained

certification from TUV Rheinland for the following standards.

● EMC Directives (2004/108/EC)

• Applicable standard (EMI) EN55011, Group 1, Class A

• Applicable standard (EMS) EN61000-6-2

● Low-voltage Directives (2006/95/EC)

• Applicable standard EN60950-1

EN50178

• Overvoltage category II

• Pollution degree 2

• The MS2 Series is designed as a Class I Equipment. Be sure to connect the protective earthing

terminal on the terminal block to the protective earthing conductor in the building installation.

• The MS2 Series is an open-type device. Be sure to install it in an appropriate enclosure rated as

IP54 or better.

• Use the MS2 Series according to the derating conditions and the installation conditions described in

this manual.

• The MS2 Series does not include a disconnecting device. Be sure to install a disconnecting device

such as a circuit breaker in the building installation wiring.

Code) in the U.S.A. (UL Category: EPBU2/EPBU8)

Installation Conditions

■ Installation environment

• Installation this unit indoors.

• Do not install this unit in locations exposed to direct sunlight.

• Do not install this unit in locations in which there is corrosive gas or flammable gas.

• Do not install this unit in locations exposed to a lot of dust, soot, or steam.

• Do not install this unit in locations in which water, oil, or chemicals may splash onto the unit.

• When installing this unit in a location subject to vibration or impact, consider the vibration proof

mounting.

■ When installing this unit in a control console

• The ambient temperature for this unit should not exceed the upper temperature limit (refer to the

derating characteristic). When the upper temperature limit may be exceeded, install a cooling fan or

cooler so that the ambient temperature is below the upper temperature limit.

• Leave a sufficient ventilation space around this unit for head dissipation.

• Do not install this unit just above a device with high head generation (transformer, inverter, servo

amplifier, etc.).

Installation

■ Space around the unit

The MS2 Series uses natural air-cooling. To ensure sufficient convection of air to dissipate heat, provide

enough space between the MS2 Series and the control panel or other nearby devices as shown below.

■ Installation orientation

Install this unit with the base A down as shown below. Do not install the unit in any other orientation.

■ Mounting bracket (optional)

Make sure that the tightening torque for the mounting screw holes of this unit is 0.5 N•m or less.
