IEC-Specific Specifications

Surge Protection Device (SPD)

DANGER
Hazard of electric shock, explosion, or arc flash
This UPS is OVCII (Over Voltage Category Class II) compliant. This UPS must only be installed in an OVCII compliant environment.
  • If the UPS is installed in an environment with an OVC rating higher than II, an SPD (surge protection device) must be installed upstream of the UPS to reduce the overvoltage category to OVCII.
  • The SPD must include a status indicator to show the user if the SPD is operational or is no longer functioning according to design. The status indicator may be visual and/or audible and/or may have remote signalling and/or output contact capability in accordance with IEC 62040-1.
Failure to follow these instructions will result in death or serious injury.

Surge Protection Device Requirements

Select a surge protection device that complies with the following requirements:

Class Type 2
Rated voltage (Ur) 230/400 V, 277/480 V
Voltage protection level (Up) < 2.5 kV
Short circuit rating (Isccr)* According to installation prospective short circuit level
Earthing system* TN-S, TT, IT, TN-C
Poles 3P/4P depending on earthing configuration
Standards IEC 61643-11 / UL 1449
Monitoring Yes

Recommended Cable Sizes for 380/400/415 V

DANGER
hazard of electric shock, explosion, or arc flash
All wiring must comply with all applicable national and/or electrical codes. The maximum allowable cable size is 25 mm2.
Failure to follow these instructions will result in death or serious injury.
NOTE: Overcurrent protection is to be provided by others.

Cable sizes in this manual are based on table B.52.3 and table B.52.5 of IEC 60364-5-52 with the following assertions:

  • 90 °C conductors

  • An ambient temperature of 30 °C

  • Use of copper conductors

  • Installation method C

PE cable size is based on table 54.2 of IEC 60364-4-54.

If the ambient temperature is greater than 30 °C, larger conductors are to be selected in accordance with the correction factors of the IEC.

NOTE: Recommended cable sizes and maximum allowable cable size may vary for the auxiliary products. Not all auxiliary products support aluminum cables. Refer to the installation manual provided with the auxiliary product.
NOTE: Neutral conductor is sized to handle 1.73 times phase current in case of high harmonic content from non-linear loads. If non or less harmonic currents are expected, neutral conductor can be sized accordingly but not less than the phase conductor.

Recommended Upstream Protection for 400 V

Upstream Protection for IEC and Minimum Prospective Phase-To-Earth Short Circuit at the UPS Input/Bypass Terminals

DANGER
Hazard of electric shock, explosion, or arc flash
The upstream overcurrent protective device (and its settings) must be sized to ensure a disconnecting time within 0.2 seconds for a minimum prospective phase-to-earth short circuit current calculated or measured at the input/bypass terminals of the UPS.
Failure to follow these instructions will result in death or serious injury.
Compliance is assured with the recommended breaker (and its settings) from the table below.

NOTICE
Risk of unintentional device operation
If a residual current-operated protective device (RCD-B) is used upstream as ground fault protection, then the RCD-B shall be sized to not trip on the leakage current of this product, which can be up to 60 mA.
Failure to follow these instructions can result in equipment damage.

Recommended Upstream Protection for 400 V IEC UPS

NOTE: For local directives which require 4-pole circuit breakers: If neutral conductor is expected to carry a high current, due to line-neutral non-linear load, the circuit breaker must be rated according to expected neutral current.

IkPh-PEis the minimum prospective phase-to-earth short circuit current required at the input/bypass terminals of the UPS. The IkPh-PE in the table is based on the recommended protective device.
