POINTS OF CAUTION

■ CONFORMITY WITH EU DIRECTIVES

•This equipment is suitable for Pollution Degree 2 and
Installation Category II (transient voltage 2500V). Re­inforced insulation (input or RS-232-C/RS-485 to power:
300V) and basic insulation (input to RS-232-C/RS-485:
300V) are maintained. Prior to installation, check that
the insulation class of this unit satisfies the system re­quirements.

•Altitude up to 2000 meters.

•The equipment must be mounted inside a panel.

•Insert noise filters. Okaya Electric Industries Model

SUP-E1H or equivalent for the power source connected to
the unit, and TDK Model ZCAT 3035-1330 or equivalent
for the RS-232-C cable are recommended.

•The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con­form to CE requirements. Failure to observe these re­quirements may invalidate the CE conformance.

•The actual installation environments such as panel con­figurations, connected devices, connected wires, may af­fect 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 conform­ity.

•Install lightning surge protectors for those wires connect­ed to remote locations.

■ POWER INPUT RATING & OPERATIONAL RANGE

•Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz, approx. 10VA

24V DC rating: 24V ±10%, approx. 7W

■ GENERAL PRECAUTIONS

•Before you remove the module, turn off the power supply
and input signal for safety.

■ ENVIRONMENT

•Indoor use.

•When heavy dust or metal particles are present in the air,

install the module inside proper housing with sufficient
ventilation.

•Do not install the module where it is subjected to continu­ous vibration. Do not subject the unit to physical impact.

•Environmental temperature must be within -5 to +60°C
(23 to 140°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.

•Be sure that the ventilation slits are not covered with ca­bles, etc.

■ WIRING

•Wrong connection may damage the module.

•Do not connect cables to moving parts or pull them tightly.

•Do not install cables close to noise sources (relay drive

cable, high frequency line, etc.).

•Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

■ AND ....

•The module is designed to function as soon as power is
supplied, however, a warm up for 10 minutes is required
for satisfying complete performance described in the data
sheet.
