Choose the option appropriate to the application and follow instructions.
operation
The H535NS is an enclosed switching relay that is connected in series between the
power source and the motor device. It operates at amperage loads up to a maximum
of 15A, and the relay controls the on/o functioning of the motor. The H535NS
requires no additional power source for operation.

3. Relay Coil Terminal Blocks: Wire the output signal from the control panel to
actuate the relay. 24 VAC/DC; 36 mA nominal
4. Relay Status LED: For positive indication of energized coil.
CAUTION!
Do not rely on status indicators to de termine whether or n ot the relay contacts are
connected to a power source. Doing so may result in i njury or death from electrical
shock.
If the connections to the unit a re made through more than one metallic conduit, bond
the conduits to prevent the hazard of elec tric shock. A bonding plate is available (Veris
pa rt AH10 ).
NOTE: If a conduit is used, connect the conduit to the mounti ng hub before connecting it to the
device. Be sure to support the H535NS housing when nipple-mounted to another en closure, or the
unit may shift on o pening, potentially causing undue stress on the wiring a nd the terminals.
