Module Rotation Feature
Installation lead wire length must be minimized because longer leads hurt performance. Lead length may be
reduced by rotating the module inside the enclosure. SPD ships with terminals pointing down. If installation
lends itself toward other orientation, the module’s aluminum backplane can be unscrewed and reoriented.
For example, if leads enter from top, rotate module assembly such that leads are shortest. Be careful with
ribbon cable connector and take care to retighten screws and secure ribbon cable. Mounting screws are in four
corners. Rectangular enclosures may be rotated up or down only.
Wiring
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E,
CSA Z462 or NOM-029-STPS.
• This equipment must only be installed and serviced by qualified electrical personnel.
• Turn off all power supplying this equipment before working on or inside equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors and covers before turning on power to this equipment.
• This equipment must be effectively grounded per all applicable codes. Use an equipment-grounding conductor to
connect this equipment to the power system ground.
• Confirm the SPD voltage rating on the module or nameplate label is not less than the operating voltage.
Failure to follow these instructions will result in death or serious injury.
The SPD200K/300K Series
Follow steps 1 through 7 to make wiring connections to units with rotary disconnect switch:
1. Turn off all power supplying this equipment before working on or inside any enclosure containing this
equipment.
2. Confirm SPD is rated for your system by comparing voltage measurements to the Line Voltage (L-L, L-N) on
the product label.
3. Identify proper location for surge protective device. Locate as close as possible to the panel being
addressed so the wires are as short as possible. Mount unit securely.
Note: The surge protective device must be installed in an accessible location as described in the NEC.
