Power Requirements - GE Mark VIe System Manual

6.3 Power Requirements

The control cabinet can accept power from multiple power sources. Each power input source (30 A / 120 V ac, 15 A / 240 V
ac, or 30 A / 125 V dc) should feed through its own external, two-pole, thermal, magnetic circuit breaker before entering the
control system enclosure. The breaker should be supplied in accordance with required site codes. The circuit breaker must be
included in the installation. If used as the panel disconnect, it must be suitably located and easily reachable. The circuit
breaker must be marked as the disconnecting device and suitably located near the equipment for servicing.
Mark VIe control systems may use up to three mains supplies; two for redundant control power (ac and / or dc) and one
auxiliary ac supply for accessories such as cabinet lights and fans. The following are example mains power supply rating
labels used on the front cabinet door where the panel main power is to be connected.
(75 [2.95])
Referencing the designators from the rating label, AC1 and optional AC2 may be 120 V ac or 240 V ac, 50/60 Hz. DC1 and
optional DC2 are 220 V dc supplies that may be used instead of AC1 and AC2. DC is an optional floating source 125 V dc
supply, usually a battery. AUXAC is used only to supply internal auxiliary appliances, such as fans, heaters, lights, or socket
outlets. The AC1, AC2, DC, DC1, or DC2 mains supplies may feed one or more Switch Mode Power Supplies to provide 28
V dc control power, or 24 or 48 V dc wetting for contact I/O circuits.
AC1 and AC2 may also feed one or two optional DACA Line Rectified Power Supplies. Each DACA is factory-set for either
120 or 240 V ac input, and provides a floating 107 V dc output. The DACA DC output may be connected through an internal
diode with the DC optional 125 V dc supply to provide diode OR'd dc redundancy to feed Switch Mode Power Supplies,
external loads such as solenoids, and /or wetting for contact I/O circuits.
Note To comply with Low Voltage Directive 2014/35/EU, all ac and dc power supply mains must connect through a Mark

VIe Overvoltage Transient Protection and EMI Filter circuit. These OV and EMI filter circuits are built-in to the JPDB and
JPDF Power Distribution Modules. If JPDB/JPDF are not used to distribute ac and dc power supply mains to the Mark VIe

control, then a separate GE Filter Module 246B8279Gx should be used to filter the mains. Refer to Mark VIe and Mark VIeS
