MOUNTING
The NSI DDS 3600R relay packs are designed to be mounted vertically. Each pack pack is provided with a reversible hangar
bracket that can be hung on up to 1 15/16" tubing, or may accept a pipe clamp. BE SURE TO USE A SAFETY CABLE TO
PREVENT INJURY IF PACK FALLS.
Since the DDS 3600R depends upon convection cooling, room air flow must be insured. Keep the air vents located on each side
of the pack pack clear of dust or any obstructions. In order for unit to cool properly the surface containing the control receptacles
must be orientated towards the floor.
If several units are to be operated in a small enclosed room, adequate ventilation must be provided to prevent the room temperature
from exceeding 100 degrees Fahrenheit
AC POWER CABLE.
This is the main power cord for your relay pack which ultimately carries all of the ac power consumed by lights connected to the
relay pack. The DDS 3600R with the NEMA 5-15 plug is limited to 1800 watts max., while the unit with the NEMA 5-20 plug
will support the full 2400 watts. It must be connected to a power source capable of supplying the total power drawn by the lights.
(See specifications for details on maximum power capability.)
WARNING: Do not remove grounding prong of AC plug. To do so may allow exposure to potentially lethal voltage levels
and will void the warranty on this product.
AC OUTPUT RECEPTACLES
The DDS 3600R has one AC receptacle for each channel. These receptacles provide power to the lamps in your lighting system.
The amount of power supplied to these outlets controls the operation of the lamps connected.
The total lamp wattage connected to each channel must not exceed the rating of each channel (see specifications). Most 120VAC
lamps and fixtures and some transformer type low-voltage fixtures may be connected to these outlets.
NOTE: Some inductive type loads such as transformers, ballasts, and motors with poor power factor may cause the relay
to output D.C. type current. This may cause the load to draw excessive current and overheat, causing damage to the
transformer, ballast, or motor. For this reason, it is necessary to insure any inductive loads are fused individually for their
respective normal operating current.
