Use this setting to install an IP20/UL Open Type drive. The applicable output current to operate the drive changes
when the ambient temperature changes:
• -10 °C to +50 °C (14 °F to 122 °F): You can operate the drive with 100% output current without derating.
• 50 °C to 60 °C (122 °F to 140 °F): Derate the output current from 100% to 80%.
Make sure that there is 60 mm (2.4 in) minimum of space between drives or between the drive and side of the
enclosure panel.
1 : Side-by-Side Mounting
Use this setting to install more than one drive Side-by-Side. The applicable output current to operate the drive
changes when the ambient temperature changes:
• -10 °C to +40 °C (14 °F to 104 °F): You can operate the drive with 100% output current without derating.
• 40 °C to 50 °C (104 °F to 122 °F): Derate the output current from 100% to 80%.
Make sure that there is 2 mm (0.08 in) minimum of space between drives.
2 : IP20/UL Type 1
Use this setting to install an IP20/UL Type 1 drive. The applicable output current to operate the drive changes when
the drive model and ambient temperature change:
• For drive models 4005 and 4008 (bypass models B003 to B007)
– -10 °C to +40 °C (14 °F to 104 °F): You can operate the drive with 100% output current without derating.
– 40 °C to 60 °C (104 °F to 140 °F): Derate the output current from 100% to 80%.
• For drive models 4011 to 4027 (bypass models B011 to B027)
– -10 °C to +50 °C (14 °F to 122 °F): You can operate the drive with 100% output current without derating.
– 50 °C to 60 °C (122 °F to 140 °F): Derate the output current from 100% to 80%.
• For drive models 4034 to 4065 (bypass models B034 to B065)
– -10 °C to +45 °C (14 °F to 113 °F): You can operate the drive with 100% output current without derating.
– 45 °C to 50 °C (113 °F to 122 °F): Derate the output current from 100% to 90%.
– 50 °C to 60 °C (122 °F to 140 °F): Derate the output current from 90% to 70%.
• For drive models 2011 to 2273 and 4077 to 4302 (bypass models D002 to D273, A002 to A248, and B302)
– -10 °C to +40 °C (14 °F to 104 °F): You can operate the drive with 100% output current without derating.
– 40 °C to 60 °C (104 °F to 140 °F): Derate the output current from 100% to 60%.
3 : IP55/UL Type 12
Use this setting to install an IP55/UL Type 12 drive. The applicable output current to operate the drive changes when
the ambient temperature changes:
• -10 °C to +40 °C (14 °F to 104 °F): You can operate the drive with 100% output current without derating.
• 40 °C to 50 °C (104 °F to 122 °F): Derate the output current from 100% to 80%.
