Specifications

Maximum input voltage to Drive (L1, L2 and L3, i.e. main power to
thyristor bridge)
480V +10% standard
525V +10% optional
660V +10% special order
Maximum recommended motor voltage
Varm = 1.15 x Vsupply
Input power supply voltage (E1, E2 and E3, i.e. auxiliary power
supply)
Balanced 3-phase 3-wire, 45Hz to 62Hz, maximum 480V +10%.
With the higher voltage (525V, 660V) versions the maximum power
supply voltage is also 480V +10%.
The input to the control (electronic) circuits is:
Standard -2-wire, 220V - 10% to 480V +10%
With North American field bridge -3-wire, 220V - 10% to 480V +10%
NOTE
E1 & E3 must be connected to the same phases as L1 & L3
Output supplies and references (Short-circuit proof)
10V reference ±5% 10mA Drive capability.
Encoder supply 300mA Drive capability at 5V, 12V or 15V selectable.
+24V supply 200mA Drive capability for relays.
All outputs are wire-proof - unaffected by accidental short circuiting.
Ambient temperature & humidity
Rated ambient temperature 40°C (104°F)
Rated maximum altitude 1000m (3200ft).
Storage temperature range -40°C to +55°C (-40°F to 131°F)
Humidity requirement non-condensing.
Derating
Nominal ratings are affected by:
1. The altitude of the installation.
Where the site is above 1000m (3200ft), reduce the normal full load
current by 1.0% for each additional 100m (320ft), up to a maximum
of 4000m.
2. The ambient temperature.
Where the local ambient temperature is above 40°C (104°F), derate
by 1.5% per °C up to 55°C (0.75% per °F up to 131°F).
Enclosure Ingress Protection
Mentor II Drives are constructed in accordance with European IP00
specification. Mentor II Drives are suitable for mounting in NEMA
ingress-protected enclosures.
The Drive must be protected against moisture and conductive
contamination. The Drive is intended for use in pollution degree 2
environments.
