CONFORMITY WITH EU DIRECTIVES OR UL
• This equipment is suitable for Pollution Degree 2, Meas-
urement Category III (input, transient voltage 6000V)
and Installation Category II (auxiliary power, transient
voltage 2500V).
And insulation class of this unit is as following.
Input to Auxiliary power supply: Reinforced insulation (550V)
Output to Auxiliary power supply: Reinforced insulation (300V)
Output to Input: Basic insulation (550V)
Prior to installation, check that the insulation class of
this unit satisfies the system requirements.
• The equipment must be mounted inside a panel.
• Altitude up to 2000 meters.
• Insert a noise filter for the power source connected to the
unit. Cosel Noise Filter Model NAC-06-472 or equivalent
is recommended.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE/UL requirements. Failure to observe these
requirements may invalidate the CE/UL conformance.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conform-
ity.
• For safety, be sure to install a circuit breaker switch as
part of the building installation that conforms to IEC
60947-2 near the 53U so as to be operated easily, and
clearly indicate that the device is used to de-energize the
53U. The circuit breaker must be provided on both side of
the line or must be “common trip” type.

AUXILIARY POWER SUPPLY RATING & OPERATIONAL
RANGE
• Locate the auxiliary power supply rating marked on the
product and confirm its operational range as indicated
below:
100 – 240V AC rating: 85 – 264V AC, 47 – 66 Hz, < 8 VA
110 – 240V DC rating: 99 – 264V DC, < 4 W (UL ap-
proval is not available)
• For UL approved model, power input terminals are
marked with L and N instead of U(+) and V(–).
■
GENERAL PRECAUTION
• Before you remove or mount the unit, turn off the power
supply and input signal for safety.
