2 INSTALLATION
2.1 LOCATION
If the units are temporarily stored or machine stops for an extended length of
time, the following precautions should be taken. Store the units at pollution level
2 or less (UL standard) and under the following conditions.
• Free from rainfall and drops of water.
• Clean and dry.
• Free from corrosive gases and liquids.
• Free from dirt and dust.
• Ambient temperature: 14 to 104°F, 10 to 40°C.
• Humidity: 90% RH or less (no condensation)
• Free from vibration.
2.2 INSTALLATION
For full use of the braking resistor unit or braking unit functions, install the units
at pollution level 2 or less (UL standard) and in a location to satisfy the following
conditions:
Figs. 1 to 8 show the external dimensions and the spaces from the periphery.
• Provide the spaces shown in Figs. 1 to 8 between the units and the
periphery.
• Since the braking resistor unit generates heat, provide sufficient
spaces from devices which are weak against heat.
• Install the units at such locations that all requirements described in
Par. 2.1 “LOCATION” are satisfied.
