2.2 Mechanical installation and location requirements
It is essential that you read and understand this section before beginning the installation .
CAUTION : To prevent equipment damage, be certain that the input power has correctly rated
protective devices installed.
CAUTION : To prevent equipment damage, be certain that input and output signals are
powered and referenced correctly.
CAUTION : To ensure reliable performance of this equipment be certain that all signals to/from
the MintDrive are shielded correctly.
CAUTION : Avoid locating the MintDrive immediately above or beside heat generating
equipment, or directly below water steam pipes.
CAUTION : Avoid locating the MintDrive in the vicinity of corrosive substances or vapors,
metal particles and dust.
The safe operation of this equipment depends upon its use in the appropriate environment.
The following points must be considered:
H
The MintDrive must be installed indoors, permanently fixed and located so that it is not accessible
by the operator and can only be accessed by service personnel using tools.
H
The maximum suggested operating altitude is 3300ft (1000m).
Above 3300ft (1000m) de-rate output current 2% per 1000ft (300m).
H
The MintDrive must be installed in an ambient temperature of 32°F to 104°F (0°C to 40°C).
De-rate output current 2.5% per 1.8°F (1°C) from 104°F (40°C) to 122°F (50°C) maximum.
H
The MintDrive must be installed in relative humidity levels of less than 80% for temperatures up to
87°F (31°C) decreasing linearly to 50% relative humidity at 104°F (40°C) (non-condensing).
H
The MintDrive must be installed where the pollution degree according to IEC664 shall not exceed 2.
H
For MintDrives that require an external 24VDC for the logic supply, it must be installed so that the
24VDC supplied to the unit is isolated from the mains using double or reinforced insulation.
H
The inputs and outputs of the control circuit must be confined to Safety Extra Low Voltage circuits.
H
Both the mains supply and the external 24VDC supply must be fused.
H
The atmosphere shall not contain flammable gases or vapors.
H
There shall not be abnormal levels of nuclear radiation or X-rays.
H
The MintDrive must be secured by the slots in the flange, with the protective earth stud bonded to a
safety earth by either a 25A conductor or a conductor of three times the peak current rating -
whichever is the greater.
H
For effective cooling and maintenance, the MintDrive should be mounted on a smooth,
non-flammable vertical surface. The power handling capability is affected by the temperature of the
left hand side of the unit. Ensure a free flow of air is available to maintain the control electronics at a
suitable temperature.
H
At least 2” (50mm) top and bottom clearance of the MintDrive must be provided for airflow.
