DANGER
The relay connection area is
designed for only high voltage
(100–240 V ac) connections. A
shock hazard can exist if low
voltage (<30V) connections are
simultaneously made in the relay
connection area.
The product enclosure is IP65; however, achieving this protection level depends
on the use of proper hardware during installation. Use standard off-the-shelf
NEMA-approved conduit hardware. Take care to select the style of conduit
hardware that will seal to the enclosure wall when using flexible or rigid conduit.
The analyzer contains four unpowered alarm relays (3 A resistive,
100–230 V ac) designed for use with high voltage (greater than 30V-RMS). The
Normally Open and Common relay contacts are connected when an alarm
condition is active. The relay connector accepts 18–12 AWG wire. Determine wire
gauge based on load application. Less than 18 AWG is not recommended.
Note:
Current to the relay contacts
must be limited to 3 amps resistive.
Local removal of power from the
relays must be available in case of
emergency or for servicing the
product. If the relay contacts are
supplied with greater than 30 Volts,
power removal can be made with an
external switch and a 3-amp fuse or
with a switched 3-amp circuit
breaker.
1.
Remotely disconnect all instrument power before opening the analyzer door.
2.
Strip the insulation on each wire back ¼-inch.
3.
Remove the front cover. Remove the shielding plate inside the instrument.
4.
Route the wire through the back right conduit opening. Use the provided
cord-connected strain reliefs. Use appropriate NEMA sealing hardware.
5.
Insert the wire ends into the connector until the insulation seats against the
connector. Refer to
and
