CAUTION
For supply connections, use wires suitable for at least 105 °C.
Utillser des fils convenant á une température de 105 °C pour les connexions d’allmenation.
Network Connected Equipment
The installation must provide a ground connection for the network equipment.
CAUTION Sweden: Apparaten skall anslutas till jordat uttang när deb abskuts till ett nätverk.
CAUTION Norway: Apparaten skall anslutas till jordat uttang nar deb abskuts till ett natverk.

a. These numbers are valid only for the specific configurations shown. Any upgrades may require a
change to the breaker size. A 5-wire source utilizes a 4 pole breaker and a 4-wire source utilizes a 3
pole breaker. The PE (Protective Earth) ground wire is not switched.
b. An input power source supplied from a 3-pole plus protective earth (PE), 4-wire system will always
be wired as 240 volts phase-to-phase, no neutral or common, plus a PE ground. Three phase input
voltage (240VAC) to the equipment is connected phase-to-phase. Examples of 4 wire: 200-volt
phase-to-phase, 208-volt phase-to-phase, 240-volt phase-to-phase
c. An input power source supplied from a 4-pole +PE, 5 wire system may be wired as either:
208VAC phase-to-phase voltage with a common, plus a PE ground. Three phase input voltage
(208VAC) to the equipment is connected phase-to-phase. The common is not connected to the
PDCA neutral terminal.
415VAC phase-to-phase voltage with a neutral return, plus a PE ground. Three phase input voltage
(230-240VAC) to the equipment is connected phase-to-neutral. The neutral is connected to the
PDCA neutral terminal. Examples of 5 wire: 208-volt phase-to-phase, 380-volt phase-to-phase,
415-volt phase-to-phase
