CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the power
terminals.
3) Installation & environment
POINTS OF CAUTION
■ ENVIRONMENT
• When heavy dust or metal particles are present in the air,
install the installation base inside proper housing and venti-
late it.
• Do not install the base where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• Environmental temperature must be within 0 to 55°C or 32
to 131°F (0 to 50°C or 32 to 122°F for AC power) 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
• Do not install cables (power supply, input and output) 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 unit 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.
MAINTENANCE
For maintaining AC power supply types, Power Supply Units
are available as follows:
• 85 – 132V AC single power supply: HDC6-1
•
85 – 132V AC two independent power sources: HDC4-K-R
• 170 – 264V AC single power supply: HDC4-L-R
Power units' standard life is expected for 10 years with
average ambient temperature 35°C (95°F) and 1.0A load.
Contact M-System for use in extremely different conditions.
