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.

Recommended Cable Sizes 400 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 150 mm². Failure to follow these instructions will result in death or serious injury.

The maximum number of cable connections per busbar: Two on input/output/bypass busbars; Four on DC+/DC- busbars; Six on N/PE busbars.

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 or aluminum 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: For the scalable UPS (GVSUPS50K150HS), always size the cables for a UPS rating of 150 kW.

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: The DC cable sizes given here are recommendations – Always follow the specific instructions in the battery solution documentation for DC cable sizes and DC PE cable sizes and ensure that the DC cable sizes match the battery breaker rating.

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.

NOTE: 20-40 kW: DC cables are sized according to 32 battery blocks. 50-100 kW: DC cables are sized according to 40 battery blocks.

Recommended Upstream Protection 400 V

DANGER
Hazard of electric shock, explosion, or arc flash For parallel systems, instantaneous override (Ii) values must not be set higher than 1250 A. Place the label 885-92556 adjacent to the upstream circuit breaker to inform about the hazard. For UPS rating 20-120 kW: In parallel systems with three or more UPSs, a circuit breaker must be installed on the output of each UPS. The unit output breaker (UOB) instantaneous override (Ii) values must not be set higher than 1250 A. For UPS rating 150 kW: In parallel systems with two or more UPSs, a circuit breaker must be installed on the output of each UPS. The unit output breaker (UOB) instantaneous override (Ii) values must not be set higher than 1250 A. Failure to follow these instructions will result in death or serious injury.

Failure to follow these instructions will result in death or serious injury.

NOTE: Only 3-pole circuit breakers are listed in the table below. For countries where local directives require 4-pole breakers in all positions, the listed references for breakers must be revised for ordering of breakers.

NOTE: For 4-pole breakers in bypass and 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.

NOTE: For the scalable UPS (GVSUPS50K150HS), always size the upstream protection for a UPS rating of 150 kW.

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 91 mA. Failure to follow these instructions can result in equipment damage.
