3 Mechanical installation
3.1 Installing the SED2 after extended storage
Recharge the capacitors in the variable speed drive following an extended period of
storage. Remember to calculate the storage time from the date of manufacture,
and not from the date of delivery. The required procedure varies according to the
storage period and is described below.
Period of storage Required action Preparation time
1 year or less Recharging not required. No preparation
1 to 2 years Before issuing the “Run” command, connect the variable speed
drive to the supply voltage for one hour.
1 hour
2 to 3 years Use a variable AC power source.
1. Apply 25% of the input voltage for 30 minutes.
2. Increase the voltage to 50% for a further 30 minutes.
3. Increase the voltage to 75% for a further 30 minutes.
4. Increase the voltage to 100% for a further 30 minutes.
The variable speed drive is then ready for operation.
2 hours
3 or more years Use a variable AC power source.
1. Apply 25% of the input voltage for 2 hours.
2. Increase the voltage to 50% for a further 2 hours.
3. Increase the voltage to 75% for a further 2 hours.
4. Increase the voltage to 100% for a further 2 hours.
The variable speed drive is then ready for operation.
8 hours
3.2 Ambient conditions
IP20 IP54
Min. operating temperature –10 °C –10 °C
Max. operating temperature +40 °C* +40 °C
* Be aware of the potential increase in temperature inside the control cabinet (derating
necessary; refer to the engineering manual).
Max. 95%, non-condensing.
If you want to install the VSD at an altitude of more than 1000 m, derating is required.
(Refer to the engineering manual).
Install the VSD vertically for optimum cooling. Do not obstruct the vents on the VSD.
Additional ventilation may be required if the drive is mounted horizontally. If mounted
vertically, VSDs with a protection standard of IP20 may be installed side by side. A
minimum clearance of 100 mm is necessary above and below the VSD. VSD of class
IP54 require greater clearances. See section 3.3.4 "Mounting SED2 drives with IP54 /
NEMA 12 rating".
Do not install the VSD in the vicinity of powerful sources for electromagnetic radiation.
