POINTS OF CAUTION
■AUXILIARY POWER
• M5XWTU does not have input terminals for auxiliary
power. The power for operation is generated from the
voltage input terminals P1 - P2, with consuming 3 VA be-
tween these terminals.
■GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the input
signal for safety.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -20 to +65°C
(-4 to +149°F) with relative humidity within 30 to 90%
RH in order to ensure adequate life span and operation.
■WIRING
• 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.
• Install lightning surge protectors for those wires connect-
ed to remote locations.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
