- 2 - PDS8 / PDS8CB
Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, with Canadian Electrical Code
CSA C22.1, and with all local codes and authorities having jurisdiction. Product is intended for indoor use only and should be installed
by qualified personnel.
1. Mount PDS8/PDS8CB in the desired location/enclosure.
2. Ensure all output jumpers [OUT1 - OUT8] are placed in the OFF (center) position marked [•].
3. Connect low voltage AC or DC power supplies to terminals marked [+ IN1 -- ], [+ IN2 -- ] (Fig. 1, pg. 2, Fig. 2 pg. 2).
Note: You can not combine AC and DC power supplies.
4. Set each output [OUT1 - OUT8] to route power from power supply 1 or 2 (jumper position 1 or 2) (Fig. 1, pg. 2, Fig. 2 pg. 2).
Note: Measure output voltage before connecting devices. This helps avoiding potential damage.
5. Turn power off before connecting devices.
6. Connect devices to terminal pairs 1 to 8, marked [P (Positive) - OUT1-OUT8, N (Negative)] (Fig. 1, pg. 2, Fig. 2 pg. 2).
Note: For DC devices carefully observe polarity. For AC devices polarity is not observed.
7. Turn main power on after all devices have been connected.
Fig. 1a - Connector plug facilitates quick installation with optional VR6 voltage regulator module (see pg. 2).
CAUTION: To avoid risk of electric shock or fire hazard, replace fuses with the same type and rating:
Input fuses: 10A/32V, Output fuses: 3A/32V.
